However, the gas flow behavior at the nanoscale is significantly different from that occurring at larger scales. In this work, we focus on a real gas effect, stemming from a strong gas intermolecular interaction force at high pressure and an un-negligible gas molecule volume at the nanoscale, on gas flow through nanoporous shale. An analytical and unified model is developed and validated with the published results of the Lattice-Boltzmann equation and experiments. This unified model covers all gas flow mechanisms, including viscous flow, slip flow and transition flow, and captures the real gas effect, which enhances flow capacity through nanoporous shale. This unified model is a ready-to-use tool for fast and accurately modeling gas flow through nanopores, and provides a basic foundation for numerical simulation and production prediction in shale gas reservoirs.

The previously proposed structural smoothing operator can effectively attenuate artifacts for relatively simple reflection structures during least-squares inversion, but it will cause damage to complicated reflection events such as discontinuities. To preserve discontinuities in a seismic image, we apply the singular spectrum analysis (SSA) operator to attenuate artifacts during least-squares inversion. Considering that global SSA cannot deal with over-complicated data very well, we use local SSA to remove noise and to better preserve the steeply dipping components. The local SSA operator corresponds to a local low-rank constraint applied in the inversion process. The migration operator used in the study is the reverse time migration (RTM) operator. Tests using the Marmousi model showed the superior performance of the proposed algorithm in preserving the discontinuities of seismic images.","[Chen, Yangkang] Univ Texas Austin, Bur Econ Geol, John A & Katherine G Jackson Sch Geosci, Austin, TX USA; [Chen, Yangkang] Oak Ridge Natl Lab, Natl Ctr Computat Sci, One Bethel Valley Rd, Oak Ridge, TN 37831 USA; [Chen, Hanming; Xiang, Kui; Chen, Xiaohong] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing, Peoples R China","Chen, YK (reprint author), Oak Ridge Natl Lab, Natl Ctr Computat Sci, One Bethel Valley Rd, Oak Ridge, TN 37831 USA.","ykchen@utexas.edu; huichanming@126.com; xiangkui15@126.com; chenxh@cup.edu.cn","Chen, Yangkang/C-3826-2016","Chen, Yangkang/0000-0001-9843-3995","Texas Consortium for Computational Seismology (TCCS); National Natural Science Foundation of China [U1262207, 41174119]; National Engineering Laboratory of Offshore Oil Exploration; 973 Program of China [2013CB228603]; National Science and Technology Program [2016ZX05010002-002]; Shell scholarship","We would like to thank S.

One of the physical origins of the above instability of reversible pump turbines is the rotating stall phenomenon generated at off-design conditions in generating mode. In this review, recent studies on the rotating stall of reversible pump turbines are critically reviewed with a focus on the generating mode. In reversible pump turbine, the rotating stall initiates at runaway and is fully developed at low discharge condition with characteristic rotating frequency being 50-70% of the impeller rotational frequency. Notorious effects induced by rotating stall include generation of large pressure fluctuation, channel blockage, and strong backflow, all of which contribute significantly to the instability of reversible pump turbine. Methods for identification of rotating stall are also introduced with plenty of examples. Finally, several suggestions on the future work are given and discussed.","[Zhang, Yuning] North China Elect Power Univ, Key Lab Condit Monitoring & Control Power Plant E, Minist Educ, Beijing 102206, Peoples R China; [Zhang, Yuning] China Univ Petr, Coll Mech & Transportat Engn, Beijing, Peoples R China; [Wu, Yulin] Tsinghua Univ, Dept Thermal Engn, Beijing, Peoples R China","Zhang, YN (reprint author), North China Elect Power Univ, Key Lab Condit Monitoring & Control Power Plant E, Minist Educ, Beijing 102206, Peoples R China.","y.zhang@ncepu.edu.cn",null,null,"National Natural Science Foundation of China [51506051]; Science Foundation of China University of Petroleum Beijing [2462016YJRC003]; Fundamental Research Funds for the Central Universities [2014ZD09]; Open Research Fund Program of State key Laboratory of Hydroscience and Engineering [sklhse-2015-E-01]; Open Research Fund Program of State key Laboratory of Water Resources AMP; Hydropower Engineering Science [2014SDG01]; Open Research Fund Program of State Key Laboratory of Power Systems [SKLD15KZ06]","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was financially supported by National Natural Science Foundation of China (Project No.: 51506051), Science Foundation of China University of Petroleum Beijing (Project No.: 2462016YJRC003), Fundamental Research Funds for the Central Universities (Project No.: 2014ZD09), Open Research Fund Program of State key Laboratory of Hydroscience and Engineering (Project No.: sklhse-2015-E-01), Open Research Fund Program of State key Laboratory of Water Resources & Hydropower Engineering Science (Project No.: 2014SDG01), and Open Research Fund Program of State Key Laboratory of Power Systems (Project No.: SKLD15KZ06).",null,71,10,11,19,21,"SAGE PUBLICATIONS LTD","LONDON","1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND","0954-4062","2041-2983",null,"P I MECH ENG C-J MEC","Proc.

Considering their unique characteristics, a set of two-dimensional industry metrics were developed to evaluate offshore O&G projects across five categories: cost, schedule, safety, production, and quantity. The project data and the results of a survey taken by industry experts were used to validate the credibility of the metrics. In addition, the drivers of each metric are discussed or verified with first principle and were confirmed by industry experts. Finally, the practice for using these metrics is recommended.

Firstly, the heated area after superheated steam (SHS) injection is distributed into three sub-areas whose heated radius are derived respectively. Next, a semi-analytical model for production performance analysis is proposed by using time discretization technique. After validation of the proposed model, production performance of CSHSS wells is analyzed in detail. The results indicate that the positive effect of residual heat on cyclic productivity improvement is offset by pressure drop and oil saturation drop. The constant pressure production (CPP) is found to be only a special case of the constant oil production (COP). Both of the cumulative oil production and thermal efficiency increase with the increase of constant oil production rate (COPR). The higher the COPR, the steeper the average pressure curve at its early stage.

Although there has been a sustained effort to reconstruct the dynamics of the phosphorus cycle over the past 3.5 billion years(2-5), it remains uncertain whether phosphorus limitation persisted throughout Earth's history and therefore whether the phosphorus cycle has consistently modulated biospheric productivity and ocean-atmosphere oxygen levels over time. Here we present a compilation of phosphorus abundances in marine sedimentary rocks spanning the past 3.5 billion years. We find evidence for relatively low authigenic phosphorus burial in shallow marine environments until about 800 to 700 million years ago. Our interpretation of the database leads us to propose that limited marginal phosphorus burial before that time was linked to phosphorus biolimitation, resulting in elemental stoichiometries in primary producers that diverged strongly from the Redfield ratio (the atomic ratio of carbon, nitrogen and phosphorus found in phytoplankton). We place our phosphorus record in a quantitative biogeochemical model framework and find that a combination of enhanced phosphorus scavenging in anoxic, iron-rich oceans(6,7) and a nutrient-based bistability in atmospheric oxygen levels could have resulted in a stable low-oxygen world. The combination of these factors may explain the protracted oxygenation of Earth's surface over the last 3.5 billion years of Earth history(8). However, our analysis also suggests that a fundamental shift in the phosphorus cycle may have occurred during the late Proterozoic eon (between 800 and 635 million years ago), coincident with a previously inferred shift in marine redox states(9), severe perturbations to Earth's climate system(10), and the emergence of animals(11,12).","[Reinhard, Christopher T.; Ozaki, Kazumi] Georgia Inst Technol, Sch Earth & Atmospher Sci, Atlanta, GA 30332 USA; [Planavsky, Noah J.; Cole, Devon B.] Yale Univ, Dept Geol & Geophys, POB 6666, New Haven, CT 06511 USA; [Gill, Benjamin C.] Virginia Tech, Dept Geosci, Blacksburg, VA 24061 USA; [Ozaki, Kazumi] Univ Tokyo, Ctr Earth Surface Syst Dynam, Kashiwanoha 2778561, Japan; [Robbins, Leslie J.; Konhauser, Kurt O.] Univ Alberta, Dept Earth & Atmospher Sci, Edmonton, AB T6G 2E3, Canada; [Lyons, Timothy W.] Univ Calif Riverside, Dept Earth Sci, Riverside, CA 92521 USA; [Fischer, Woodward W.] CALTECH, Div Geol & Planetary Sci, Pasadena, CA 91125 USA; [Wang, Chunjiang] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing 102249, Peoples R China","Reinhard, CT (reprint author), Georgia Inst Technol, Sch Earth & Atmospher Sci, Atlanta, GA 30332 USA.; Planavsky, NJ (reprint author), Yale Univ, Dept Geol & Geophys, POB 6666, New Haven, CT 06511 USA.","chris.reinhard@eas.gatech.edu; noah.planavsky@yale.edu","Gill, Benjamin/B-8047-2012","Gill, Benjamin/0000-0001-7402-0811","NSF-EAR; NASA Astrobiology Institute; Alfred P.

Existing tools typically require users to select and brush geospatial regions on a map when retrieving and exploring taxi trajectories and passenger trips. To answer seemingly simple questions such as \"What were the taxi trips starting from Main Street and ending at Wall Street in the morning?\" or \"Where are the taxis arriving at the Art Museum at noon typically coming from?\", tedious and time consuming interactions are usually needed since the numeric GPS points of trajectories are not directly linked to the keywords such as \"Main Street\", \"Wall Street\", and \"Art Museum\". In this paper, we present SemanticTraj, a new method for managing and visualizing taxi trajectory data in an intuitive, semantic rich, and efficient means. With SemanticTraj, domain and public users can find answers to the aforementioned questions easily through direct queries based on the terms. They can also interactively explore the retrieved data in visualizations enhanced by semantic information of the trajectories and trips. In particular, taxi trajectories are converted into taxi documents through a textualization transformation process. This process maps GPS points into a series of street/POI names and pick-up/drop-off locations. It also converts vehicle speeds into user-defined descriptive terms. Then, a corpus of taxi documents is formed and indexed to enable flexible semantic queries over a text search engine. Semantic labels and meta-summaries of the results are integrated with a set of visualizations in a SemanticTraj prototype, which helps users study taxi trajectories quickly and easily. A set of usage scenarios are presented to show the usability of the system. We also collected feedback from domain experts and conducted a preliminary user study to evaluate the visual system.","[Al-Dohuki, Shamal; Kamw, Farah; Zhao, Ye; Ma, Chao; Wu, Yingyu] Kent State Univ, Dept Comp Sci, Kent, OH 44240 USA; [Yang, Jing] UNC Charlotte, Dept Comp Sci, Charlotte, NC USA; [Ye, Xinyue] Kent State Univ, Dept Geog, Kent, OH USA; [Wang, Fei; Chen, Wei] Zhejiang Univ, Dept Comp Sci, Hangzhou, Zhejiang, Peoples R China; [Li, Xin] China Petr Univ, Beijing, Peoples R China","Zhao, Y (reprint author), Kent State Univ, Dept Comp Sci, Kent, OH 44240 USA.","sadohuki@kent.edu; fkamw@kent.edu; zhao@cs.kent.edu; cma1@kent.edu; ywu23@kent.edu; jyangl3@uncc.edu; xye5@kent.edu; wolflyecn@gmail.com; chenwei@cad.zju.edu.cn",null,null,"US NSF [1535031, 1535081, 1416509]; 973 Program of China [2015CB352503]; NSFC [61232012, 61422211]","We thank the reviewers for their highly constructive feedback and suggestions.

We first flatten the primary reflections in common midpoint gather using the automatically picked normal moveout velocities that correspond to the primary reflections and then randomly permutate all the traces. Next, we remove the spatially distributed random spikes that correspond to the multiple reflections using the EMD-based smoothing approach that is implemented in the f-x domain. The trace randomization approach can make the spatially coherent multiple reflections random along the space direction and can decrease the coherency of near-offset multiple reflections. The EMD-based smoothing method is superior to median filter and prediction error filter in that it can help preserve the flattened signals better, without the need of exact flattening, and can preserve the amplitude variation much better. In addition, EMD is a fully adaptive algorithm and the parameterization for EMD-based smoothing can be very convenient.","[Chen, Wei] Yangtze Univ, Minist Educ, Key Lab Explorat Technol Oil & Gas Resources, Wuhan 430100, Peoples R China; [Chen, Wei] Hubei Cooperat Innovat Ctr Unconvent Oil & Gas, Wuhan 430100, Peoples R China; [Xie, Jianyong; Zu, Shaohuan; Gan, Shuwei] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing 102200, Peoples R China; [Xie, Jianyong] Univ Alberta, Dept Phys, Edmonton, AB T6G 2E1, Canada; [Chen, Yangkang] Univ Texas Austin, Jackson Sch Geosci, Austin, TX 78713 USA; [Chen, Yangkang] Oak Ridge Natl Lab, Oak Ridge, TN 37830 USA","Chen, W (reprint author), Yangtze Univ, Minist Educ, Key Lab Explorat Technol Oil & Gas Resources, Wuhan 430100, Peoples R China.","chenwei2014@yangtzeu.edu.cn; xjyshl@sina.com; shaohuanzu@gmail.com; gsw19900128@126.com; chenyk2016@gmail.com","Chen, Yangkang/C-3826-2016","Chen, Yangkang/0000-0001-9843-3995","Sinopec Key Laboratory of Geophysics [33550006-15-FW2099-0017]; Texas Consortium for Computational Seismology","This work was supported in part by the Sinopec Key Laboratory of Geophysics under Grant 33550006-15-FW2099-0017 and in part by Texas Consortium for Computational Seismology.",null,38,11,11,7,10,"IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC","PISCATAWAY","445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA","1545-598X","1558-0571",null,"IEEE GEOSCI REMOTE S","IEEE Geosci.

This study aims to evaluate the promotion impact of the response capability of smart home consumers on the distributed PV penetration using non-cooperative game theoretical analysis. In the analysis, the Nash equilibrium can be found for consumers with different levels of demand response capability in an electricity market with real-time pricing (RTP) mechanism under different PV installed capacities and battery capacities. As a case study, 5 levels of consumers' response capability, 32 combinations of PV installed capacities and battery capacities were analyzed and inter-compared using the developed model. The results show that: (i) the consumers with higher response capability are able to accept larger PV capacity because the marginal revenue of new installed PV for smart consumers decreases much more slowly compared to that of a common consumer; (ii) the consumers with higher response capability need less batteries to promote PV economic acceptability; (iii) the consumers with higher response capability can meet the electricity demand in real-time with least expenditure, so they get more ultimate benefit from the games.

The desorption characteristics and origin of in-situ shale gas extraction in the lower Cambrian Shuijingtuo Formation of the Sichuan Basin are studied via in-situ gas desorption tests. Tests are conducted at both reservoir (35 degrees C) and high temperatures (90 degrees C). The results indicate that most in-situ shale gas is quickly desorbed within 300 min at both the reservoir temperature desorption stage and the high temperature desorption stage. In both instances, the in-situ gas desorption rates decrease rapidly over time. In addition, the desorbed gas content and desorption rate at the reservoir temperature desorption stage are both clearly lower than the equivalent measures at the high temperature desorption stage. The in-situ desorbed gas from the reservoir temperature desorption stage is mainly free gas; the in-situ desorbed gas from the high temperature desorption stage, on the other hand, is mainly sorbed gas, which is the dominant form in the in-situ shale gas. The percentage of in-situ desorbed gas at these two stages is mainly controlled by gas adsorption, pore volume, and specific surface area. The desorption rate of in-situ shale gas is likely controlled primarily by average pore size and methane adsorption. (C) 2016 Elsevier Ltd.

The relationship between anisotropic permeability and fracture structure as characterised by micro-computed tomography (CT) and scanning electron microscope (SEM) Maps was also investigated. At confining pressure of 3 MPa, permeability parallel to bedding of the three shales varies between 37.6 and 3042.4 nanodarcies (nd), while permeability perpendicular to bedding varies between 3.6 and 17.3 nd, using helium and methane. The permeability anisotropy ratio between the parallel and perpendicular to bedding directions varies from 5.2 to 510.5 for the three samples using the two gases. Moreover, permeability in two parallel to bedding directions also shows strong anisotropy. The CT and SEM Maps results suggest that microfractures are critical to permeability in the parallel to bedding direction; they also lead to a higher anisotropy ratio between the parallel and perpendicular to bedding directions, while reducing the anisotropy ratio between the parallel to bedding directions. The helium permeability is 1.4 to 3.3 times that of methane permeability, while the helium to methane permeability ratio decreases with the sample's total organic carbon content: an observation that requires further investigation.

The classic version of Cadzow rank-reduction method arranges the 4-D spatial data into a level-four block Hankel/Toeplitz matrix and then applies truncated singular value decomposition (TSVD) for rank reduction. When the observed data are extremely noisy, which is often the feature of real seismic data, traditional TSVD cannot be adequate for attenuating the noise and reconstructing the signals. The reconstructed data tend to contain a significant amount of residual noise using the traditional TSVD method, which can be explained by the fact that the reconstructed data space is a mixture of both signal subspace and noise subspace. In order to better decompose the block Hankel matrix into signal and noise components, we introduced a damping operator into the traditional TSVD formula, which we call the damped rank-reduction method. The damped rank-reduction method can obtain a perfect reconstruction performance even when the observed data have extremely low signal-to-noise ratio. The feasibility of the improved 5-D seismic data reconstruction method was validated via both 5-D synthetic and field data examples. We presented comprehensive analysis of the data examples and obtained valuable experience and guidelines in better utilizing the proposed method in practice.

However, this signal subspace actually still contains residual noise. We have derived a new formula of low-rank reduction, which is more powerful in distinguishing between signal and noise compared with the traditional TSVD. By introducing a damping factor into traditional MSSA to dampen the singular values, we have developed a new algorithm for random noise attenuation. We have named our modified MSSA as damped MSSA. The denoising performance is controlled by the damping factor, and our approach reverts to the traditional MSSA approach when the damping factor is sufficiently large. Application of the damped MSSA algorithm on synthetic and field seismic data demonstrates superior performance compared with the conventional MSSA algorithm.","[Huang, Weilin; Wang, Runqiu; Li, Huijian; Gan, Shuwei] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing, Peoples R China; [Chen, Yangkang] Univ Texas Austin, Bur Econ Geol, John A & Katherine G Jackson Sch Geosci, Austin, TX USA","Huang, WL (reprint author), China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing, Peoples R China.","cup_hwl@126.com; wrq@cup.edu.cn; ykchen@utexas.edu; lihuijian1117@163.com; gsw19900128@126.com","Chen, Yangkang/C-3826-2016","Chen, Yangkang/0000-0001-9843-3995","National Council for Scientific and Technological Development (CNPq-Brazil); National Institute of Science and Technology of Petroleum Geophysics (INCT-GP-Brazil); Center for Computational Engineering and Sciences (Fapesp/Cepid, Brazil) [2013/08293-7]; Wave Inversion Technology (WIT) Consortium","The authors thank SMAART-JV for providing the Sigsbee2B-NFS data set.

We have also devised a new form of the iterative method to remove interference generated from the simultaneous source acquisition. In each iteration, we have estimated the interference using the blending operator following the proposed formula and then subtracted the interference from the pseudodeblended data. To further eliminate the incoherent interference and constrain the inversion, the data were then transformed to an auxiliary sparse domain for applying a thresholding operator. During the iterations, the threshold was decreased from the largest value to zero following an exponential function. The exponentially decreasing threshold aimed to gradually pass the deblended data to a more acceptable model subspace. Two numerically blended synthetic data sets and one numerically blended practical field data set from an ocean bottom cable were used to demonstrate the usefulness of our proposed method and the better performance of the periodically varying code over the traditional random dithering code.","[Zu, Shaohuan; Zhou, Hui; Zou, Xiaofeng] China Univ Petr, State Key Lab Petr Resources & Prospecting, CNPC, Key Lab Geophys Explorat, Beijing, Peoples R China; [Chen, Yangkang] Univ Texas Austin, Bur Econ Geol, John A & Katherine G Jackson Sch Geosci, Austin, TX USA; [Qu, Shan] Delft Univ Technol, Dept Imaging Phys ImPhys, Lab Acoust Wavefield Imaging, Delft, Netherlands; [Chen, Haolin; Liu, Renwu] BGP Inc, CNPC, Dagang Dept, Tianjin, Peoples R China","Zu, SH (reprint author), China Univ Petr, State Key Lab Petr Resources & Prospecting, CNPC, Key Lab Geophys Explorat, Beijing, Peoples R China.","zushaohuan@qq.com; huizhou@cup.edu.cn; ykchen@utexas.edu; S.Qu@tudelft.nl; 731891645@qq.com; chenhaolin@bgp.com.cn; liurenwu@bgp.com.cn","Chen, Yangkang/C-3826-2016","Chen, Yangkang/0000-0001-9843-3995","973 Program of China [2013CB228603]; National Major Science and Technology Program [2016ZX05010001-002]; Texas Consortium for Computational Seismology (TCCS)","We thank Dagang seismic exploration company (BGP, CNPC) for providing the marine data sets.

However, previous research concerning shales has predominantly focused on marine shales and barely on continental shales. In this study, geochemical and mineralogical analyses, high-pressure mercury intrusion and low-pressure adsorption were performed on 18 continental shale samples obtained from a currently active shale gas play, the Chang 7 member of Yanchang Formation in the Ordos Basin. A comparison of all these techniques is provided for characterizing the complex pore structure of continental shales. Geochemical analysis reveals total organic carbon (TOC) values ranging from 0.47% to 11.44%, indicating that there is abundant organic matter (OM) in the study area. Kerogen analysis shows vitrinite reflectance (Ro) of 0.68%-1.02%, indicating that kerogen is at a mature oil generation stage. X-ray diffraction mineralogy (XRD) analysis indicates that the dominant mineral constituents of shale samples are clay minerals (which mainly consist of illite, chlorite, kaolinite, and negligible amounts of montmorillonite), quartz and feldspar, followed by low carbonate content. All-scale pore size analysis indicates that the pore size distribution (PSD) of shale pores is mainly from 0.3 to 60 nm. Note that accuracy of all scale PSD analysis decreases for pores less than 0.3 nm and more than 10 gm. Experimental analysis indicates that mesopores (2-50 nm) are dominant in continental shales, followed by micropores (<2 nm) and macropores (50 nm-10 gm). Mesopores have the largest contribution to pore volume (PV) and specific surface area (SSA). In addition, plate- and sheet-shaped pores are dominant with poor connectivity, followed by hybrid pores. Results of research on factors controlling pore structure development show that it is principally controlled by clay mineral contents and Ro, and this is different from marine systems. This study has important significance in gaining a comprehensive understanding of continental shale pore structure and the shale gas storage seepage mechanism. (C) 2016 Elsevier Ltd.

In this study, pores are classified as intergranular, intraparticle, and organic pores based on the location of their occurrence. The heterogeneities of the three pore types and their effects on the occurrence of shale gas, which is of utmost practical importance for shale gas exploration and development, are discussed. In this study, the three types of pores are quantitatively characterized using fractal and multifractal methods. The mean fractal dimension and mean width of the multifractal spectrum of these pores are found to be different, i.e., 1.5985 and 1.665 for intraparticle pores, 1.5869 and 1.475 for intergranular pores, and 1.6 and 13725 for organic pores. Intraparticle pores have the highest heterogeneity, intergranular pores have intermediate heterogeneity, and organic pores have the lowest heterogeneity. SEM images show that organic pores have good connectivity, homogeneous distribution, and small range of aperture change but have the lowest heterogeneity even where pores are abundant; thus, they provide the largest shale gas occurrence space. In contrast, intergranular pores are less abundant, have lower connectivity, and have higher heterogeneity than organic pores, thereby providing a relatively smaller shale gas occurrence space. Finally, intraparticle pores are the least abundant and possess the poorest connectivity, largest range of aperture change, and highest heterogeneity of the three pore types, thereby providing the smallest shale gas occurrence space. We conclude that organic pores are crucial to the occurrence of shale gas and can provide a new index for the evaluation of shale gas exploration and development. (C) 2016 Elsevier Ltd.

Pore structure characteristics of Lower Silurian Longmaxi shales from southern Sichuan Basin were investigated. The combination of field emission scanning electron microscope (FE-SEM) and argon ion beam milling was utilized to describe the nanometer-to micrometer-scale (>1.2 nm) pore systems. The shales were characterized by organic geochemical and mineralogical analyses. Total porosity, pore size distribution (PSD), specific surface area, and gas content were determined. Controls of organic matter richness, thermal maturity, and mineralogy on porosity were examined. The contribution of individual mineral components to total porosity was analyzed quantitatively. Total gas contents of the shales determined from canister desorption data were compared with theoretical (sorptive and volumetric) gas storage capacities. The total organic carbon (TOC) content of the shale samples ranges between 0.1 and 8.0 wt.% and helium porosity varies between 0.7 and 5.7%. Maturity in terms of equivalent vitrinite reflectance of bitumen (R-eqv) ranges from 1.8 to 3.2%. TOC content is a strong control for the pore system of these shales, and shows a positive correlation with porosity. Porosity increases with increasing thermal maturity when R-eqv is less than 2.5%, but decreases for higher thermal maturity samples. FE-SEM reveals four pore types related to the rock matrix that are classified as follows: organic matter (OM)-hosted pores, pores in clay minerals, pores of framework minerals, and intragranular pores in microfossils. Pores in clay minerals are always associated with the framework of clay flakes, and develop around rigid mineral grains because the pressure shadows of mineral grains prevent pores from collapsing. Pores of framework minerals are probably related to dissolution by acidic fluids, and the dissolution-related pores promote porosity of shales. A unimodal PSD exists in the micropore range of TOC-rich samples, while the PSD of carbonate-rich samples are bimodal. A PSD maximum in the micropore range is attributed by OM and another maximum in the range of mesopore-macropores is probably caused by the dissolution of carbonate minerals. Quantitative evaluation of the contribution of individual mineral components to porosity shows that the organic matter contributes approximately 62% to the total porosity. Framework minerals (quartz, feldspar, and carbonates, et al.) and clay minerals contribute 25% and 13%, respectively. The total gas content of these shales ranges from 0.4 to 62 m(3)/t, and the total gas contents of selected samples determined from canister desorption tests agree with the theoretically estimated original gas-in-place (OGIP).

In this paper, we focus on the velocity analysis of simultaneous-source data using the normal moveout-based velocity picking approach. We demonstrate that it is possible to obtain a precise velocity model directly from the blended data in the common-midpoint domain. The similarity-weighted semblance can help us obtain much better velocity spectrum with higher resolution and higher reliability compared with the traditional semblance. The similarity-weighted semblance enforces an inherent noise attenuation solely in the semblance calculation stage, thus it is not sensitive to the intense interference. We use both simulated synthetic and field data examples to demonstrate the performance of the similarity-weighted semblance in obtaining reliable subsurface velocity model for direct migration of simultaneous-source data. The migrated image of blended field data using prestack Kirchhoff time migration approach based on the picked velocity from the similarity-weighted semblance is very close to the migrated image of unblended data.","[Gan, Shuwei; Wang, Shoudong; Zu, Shaohuan] China Univ Petr, State Key Lab Petr Resources & Prospecting, Fuxue Rd 18th, Beijing 102200, Peoples R China; [Chen, Yangkang] Univ Texas Austin, Bur Econ Geol, John A & Katherine G Jackson Sch Geosci, Univ Stn, Box X, Austin, TX 78713 USA; [Qu, Shan] Delft Univ Technol, Fac Sci Appl, Dept Imaging Phys, NL-2600 CD Delft, Netherlands","Gan, SW (reprint author), China Univ Petr, State Key Lab Petr Resources & Prospecting, Fuxue Rd 18th, Beijing 102200, Peoples R China.","wangshoudong@163.com",null,null,"National Natural Science Foundation of China [41274137]; National Science and Technology of Major Projects of China [2011ZX05019-006]; National Engineering Laboratory of Off-shore Oil Exploration; Texas Consortium for Computational Seismology (TCCS)","We would like to thank Pan Deng and Keling Chen for helpful discussions about similarity-weighted semblance, Jiang Yuan, Zhaoyu Jin, Ray Abma, Min Zhou, Araz Mahdad and Sergey Fomel for inspiring discussions about simultaneous-source acquisition.

The force between gas molecules and the volume of the gas molecules themselves cannot be negligible in shale gas reservoirs with high pressure and nanoscale pores, influences gas transport and must be taken into account as a real gas effect. During depressurization development of shale gas reservoirs, the adsorbed gas desorption and a decrease in an adsorption layer influence gas transport. Meanwhile, due to the stress dependence, decreases in intrinsic permeability, porosity and a pore diameter also influence gas transport. In this work, a unified model for gas transport in organic nanopores of shale gas reservoirs is presented, accounting for the effects of coupling the real gas effect, stress dependence and an adsorption layer on gas transport. This unified model is developed by coupling a bulk gas transport model and an adsorbed gas surface diffusion model. The bulk gas transport model is validated with published molecular simulation data, and the adsorbed gas surface diffusion model is validated with published experimental data. The results show that (1) in comparison with the previous models, the bulk gas transport model developed on the basis of a weighted superposition of slip flow and Knudsen diffusion can more reasonably describe bulk gas transport, (2) surface diffusion is an important transport mechanism, and its contribution cannot be negligible and even dominates in nanopores with less than 2 nm in diameter, and (3) the effect of stress dependence on fluid flow in shale gas reservoirs is significantly different from that in conventional gas reservoirs, and is related to not only the shale matrix mechanical properties and the effective stress but also the gas transport mechanisms.

Compared with TiO2 nanowire/graphene and N-doped TiO2 nanowire/graphene composites, the N-TiO2/NG heterostructures demonstrate a better photocatalytic performance for the degradation of methylene blue under visible light irradiations, as well as displaying a better recyclability. It is found that the nitrogen atoms originated from the decomposition of urea were not only entered into the lattice of TiO2 nanowires but also doped into the skeleton of graphene nanosheets.

The high resolution of the time-frequency representation is of great importance to depict geological structures. In this letter, we propose a novel seismic time-frequency analysis approach using the newly developed empirical wavelet transform (EWT). It is the first time that EWT is applied in analyzing multichannel seismic data for the purpose of seismic exploration. EWT is a fully adaptive signal-analysis approach, which is similar to the empirical mode decomposition but has a consolidated mathematical background. EWT first estimates the frequency components presented in the seismic signal, then computes the boundaries, and extracts oscillatory components based on the boundaries computed. Synthetic, 2-D, and 3-D real seismic data are used to comprehensively demonstrate the effectiveness of the proposed seismic time-frequency analysis approach. Results show that the EWT can provide a much higher resolution than the traditional continuous wavelet transform and offers the potential in precisely highlighting geological and stratigraphic information.","[Liu, Wei; Cao, Siyuan] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing 102249, Peoples R China; [Chen, Yangkang] Univ Texas Austin, Jackson Sch Geosci, Austin, TX 78713 USA","Liu, W (reprint author), China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing 102249, Peoples R China.","liuwei_upc@126.com; csy@cup.edu.cn; ykchen@utexas.edu","Chen, Yangkang/C-3826-2016","Chen, Yangkang/0000-0001-9843-3995","Australian Government; Western Australian Government; North West Shelf Joint Venture Partners; Western Australian Energy Research Alliance","The authors would like to thank J.

We observe strong low S-wave velocity beneath the Changbaishan volcano in the upper mantle to at least 200-km depth, which is interpreted as a mantle upwelling beneath the Changbaishan volcano that is consistent with the body wave tomographic image. The Songliao Basin is dominated by a high velocity extending to at least 200-km depth. Built upon the observed velocity anomalies, we propose a sub-lithosphere mantle convection model for NE China in which the upwelling of upper mantle materials from the mantle transition zone to the Changbaishan volcano could induce a local sub-lithosphere convection in the upper mantle and the strong high velocity of the upper mantle beneath the Songliao Basin corresponds to the downwelling limb of this convection cell. The downwelling beneath the Songliao Basin could also induce secondary local convection in the asthenosphere to the west, leading to local asthenospheric upwelling beneath the Abaga and Halaha volcanoes in the Xing'an-Mongolia Orogenic Belt.

The principle of the proposed approach is to first flatten the seismic record in local spatial windows and then to apply a traditional median filter (MF) to the third flattened dimension. The key component of the proposed approach is the estimation of the local slope, which can be calculated by first scanning the NMO velocity and then transferring the velocity to the local slope.

The results suggest that the N-MWCNT is favorable for the dispersion of few layer MoS2 nanosheets due to the strong interaction between the N-containing groups and Mo precursor. The N-MWCNT coated with few layer MoS2 (MoS2/N-MWCNT) exhibits the highest HER activity: onset potential of 90 mV vs. reversible hydrogen electrode, Tafel slope of 40 mV dec(-1), high current density of 80.3 mA cm(-2) at overpotential 0.2 V, together with excellent stability during 10,000 cycles. Such high HER activity is superior to most of MoS2 based catalysts reported so far, and attributed to the intimate contacts between highly conductive network of N MWCNT and thin MoS2 nanosheets, the high quantity of unsaturated sulfur atoms or the bridging S-2(2-), and high pyridinic and graphitic N concentrations. This work shows that the few-layer MoS2 nanosheets coated on conductive N-doped MWCNT has a great potential for electrocatalytic hydrogen evolution.

The effect of total organic carbon content, temperature, thermal maturity, mineral composition, and pore structure on methane sorption capacity has been investigated. A linear combination approach has been developed to predict the Langmuir sorption capacity of shales based on the mass fractions of their organic and inorganic components. This information can be used to estimate the in situ sorption capacity of shale layers as a function of burial depth (formation pressure and temperature), and composition. Methane sorption capacity of the dry shales shows a positive relationship with TOC and specific surface area. The Langmuir pressure decreases with increasing maturity, but the TOC-normalized Langmuir sorption capacity of over-mature shales also decreases with increasing thermal maturity. This may be related to the carbonization of highly over-mature organic matter. For the samples investigated, approximately 16.3%-46.7% (average 28.6%) of the methane sorption can be attributed to clay minerals and 46.5%-81.5% to (average 67.6%) organic matter in these shales, respectively. Using the linear combination approach, the calculated Langmuir sorption capacity function matches the measured values reasonably. Methane sorption capacity computed as a function of depth (for a mean hydrostatic pressure gradient of 0.01 MPa/m and a geothermal gradient of 0.03 degrees C /m) shows a rapid increase and reaches a maximum between 900 and 1800 m followed by a slow decrease with increasing depth. At shallow burial depths (<900-1800 m), the sorption capacity is controlled by the combination of hydrostatic pressure and geothermal gradients. At deeper burial (>900-1800 m) sorption capacity is controlled by the geothermal gradient. Higher geothermal gradients result in a steeper decline of sorption capacity. (C) 2015 Elsevier B.V.

The working fluid selection and system parameters optimization are the main approaches to improve geothermal ORC systems performance. Zeotropic mixtures are showing promise as ORC working fluids due to the better match between the working fluid and the heat source/sink temperatures. This study optimizes the cooling water temperature rise as well as the evaporation and condensation pressures of isobutane/isopentane (R600a/R601a) mixtures for various mole fractions to maximize the net power output of a geothermal ORC for geothermal water temperatures of 110 degrees C, 130 degrees C and 150 degrees C and reinjection temperatures not less than 70 degrees C. Two mole fractions maximize the turbine power generation, while the maximum net power output occurs for R600a mole fractions from 0.7 to 0.9 due to the variation of the parasitic power consumed by the working fluid feed pump and the cooling water circulating pump. A geothermal ORC using R600a/R601 can generate 11%, 7% and 4% more power than an ORC using pure R600a for geothermal water inlet temperatures of 110 degrees C, 130 degrees C and 150 degrees C, respectively. Both the evaporator and condenser area per unit power output using R600a/R601a are higher than that using pure R600a or R601a due to the reduction in the heat transfer coefficient and the temperature difference between the mixture working fluid and the heat source/sink. The total heat transfer area per unit power output increases to a maximum at an R600a mole fraction of 0.5 and then decreases with increasing R600a mole fraction. The total heat transfer area can be reduced for the same power output with higher geothermal source temperatures. The turbine using R600a/R601a with higher R600a mole fractions is nearly the same size as a turbine using pure R600a. (C) 2015 Elsevier Ltd.

The effect of the variation in material composition on the heterogeneous pore structure of high-maturity shale of the Silurian Longmaxi formation was analyzed based on fractal geometry using field emission scanning electron microscopy (FE-SEM), low-pressure N-2 adsorption, and high-pressure mercury intrusion porosimetry (MIP). The results show that abundant micro- and nano-scale pores were distributed in all shale samples, with the majority of pores composed of ink-bottle-shaped organic pores and slit-shaped mineral matrix pores. Samples with different total organic carbon (TOC) contents and mineral compositions showed distinct differences in pore structure. Organic matter and clay mineral primarily affected the mesopore structure, and the heterogeneity of the mesopore structure increased with the clay mineral content. Plastic minerals, such as quartz and carbonate, primarily affected the macropore structure. The increase in the quartz content could reduce the heterogeneity of the macropore structure, and an increase in the carbonate mineral content could increase the heterogeneity of the macropore structure. Finally, organic matter could strengthen the heterogeneity of the macropore structure only when the TOC content was greater than 1.1 wt. %. (C) 2015 Elsevier B.V.

The scenarios were developed using Geologic Resources Supply-Demand Model (GeRS-DeMo). The Low and Best Guess (BG) scenarios suggest that world fossil fuel production may peak before 2025 and decline rapidly thereafter. The High scenario indicates that fossil fuels may have a strong growth till 2025 followed by a plateau lasting approximately 50 years before declining. All three scenarios suggest that world coal production may peak before 2025 due to peaking Chinese production and that only natural gas could have strong growth in the future. In addition, by converting the fossil fuel projections to greenhouse gas emissions, the projections were compared to IPCC scenarios which indicated that based on current estimates of URR there are insufficient fossil fuels to deliver the higher emission IPCC scenarios A1Fl and RCP8.5.

In this area, the tectonic condition is complex and the organic matter is over-matured, so conventional oil and gas exploration have not previously been considered. During a recent shale gas exploration, canister-desorbed gas contents of more than I m(3)/t were detected from 490 to 825 m depth, with a maximum value of 3.18 m(3)/t at 762 m. Hence to understand the mechanism of preservation of the gas is important. The gas shales have a total organic carbon (TOC) content of between 0.44% and 6.91%, and vitrinite-like macerals reflectance (R-o) between 33% and 43% with type II kerogen. The porosity of 22 gas shale samples ranges between 0.4% and 2.29%, and their permeability is between 6.9 x 10(-5) and 3.8 x 10(-1) mD. To investigate the shale's pore structure and its relation to gas storage behavior, we studied the microscopic mechanism of gas preservation using a combination of pore characterization techniques, including focused ion beam-scanning electron microscope (FIB-SEM) imaging, and comparison of gas sorption and free gas storage capacity. Folding, thrusting and subsequent rapid uplifting movements occurred after most of the dry gas had been originally generated, and the present gas is a mixture originated from the cracking of liquid hydrocarbons at high maturity and kerogen pyrolysis in the early hydrocarbon-generation phase. SEM observations, combined with low temperature gas adsorption and mercury injection capillary pressure analyses, show that pores within the organic matter or the mineral particles in the Lujiaping Shale are rare, while the nanometer-sized pores (1-4 nm) between organic matter and clay mineral particles, especially in cleavage domains, are greatly developed. Thus the gas in these shales is mainly adsorbed gas due to the limited free gas storage space. This is unlike most other shale gas reservoirs, pores within the organic matter and pores between or within mineral particles are dominant. Moreover, the desorbed gas content correlates well with TOC content and the microporous and mesoporous specific surface area determined bylaw temperature CO2 and N-2, respectively, suggesting that the nanometer-sized pores associated with the organic matter make up the fundamental storage space for this shale. The calculations based on FIB-SEM observation showed that the nanometer-sized intergranular pores have large specific surface areas, with their small pore throat diameters resulting in high capillary pressure. These characteristics have contributed to the preservation of shale gas in this complex tectonic area. (C) 2014 Elsevier B.V.

The obtained products were characterized by means of X-ray diffraction, FT-IR transmission spectroscopy, electron microscopy, UV-vis diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, etc. Compared with g-C3N4 and commercial P25, the as-prepared photocatalysts exhibit enhanced photocatalytic performance for photoreduction of CO2 in the presence of water vapor at room temperature. It was found that the mass ratios of urea to Ti(OH)(4) in precursors play a role in formation of the composites, and the high ratios of urea to Ti(OH)(4) result in the composites of g-C3N4 and N-doped TiO2, while low ratios only result in N-doped TiO2. An interesting selectivity of photocatalytic products displayed that N-doped TiO2 samples were related to CH4 and CO generation, while g-C3N4 and N-TiO2 composites were related to CO generation, and the product selectivity may originate from the formed g-C3N4. The highest amount of CO (14.73 mu mol) was obtained on the optimized photocatalyst under 12 h light irradiation, which is four times of that over commercial P25. Based on these results, a possible mechanism for the enhanced photocatalytic performance was proposed. (C) 2014 Elsevier B.V.

However, the formation mechanism of effective fracture network has not been well understood. The mechanism of fracture propagation in shale with hydraulic fracturing needs to be further explored, in order to realize the control on morphology of fracture network with SRV and increase the single well production of shale gas. In this article, the true triaxial test system was deployed for horizontal well hydraulic fracturing simulation experiments of shale outcrops for the first time. The effects of multiple factors on propagating rules of fractures of horizontal well in shale with SRV were studied, and the fracture morphology of post- fracturing rock cores was observed for the first time by high- energy CT scanning using the large- scale non- destructive testing system based on linear accelerator. The results show that the influence of flow rate (for SRV) on fracture complexity differs when its value falls in different intervals. When the horizontal in situ stress difference is less than 9 MPa, the hydraulic fracture easily propagates along the natural fractures, forming a fracture network. In this range, when the stress difference is increased, the appearance of the main hydraulic fracture contributes to interconnecting more natural fractures, forming a relatively more complex fracture system. Under the condition of the same horizontal stress difference, if the coefficient of stress difference K-h > 0.25, there is an obvious trend to form single main fracture. The effects of viscosity of fracturing fluid and flow rate on the fracture propagation can be expressed by the parameter q mu . When the order of magnitude of q mu value is 10 (9) N m, it is favorable to the generation of fracture network, but too small or too large values are both harmful. The development and cementing strength of depositional beddings seriously affect the propagating complexity of fracture network with hydraulic fracturing. Refracturing helps to produce some new fractures which are different from the initial ones, and better fracturing effect is achieved. The fracture initiation morphology in perforation fracturing is closely related to the distribution of natural fractures (depositional bedding) around the perforations. If the pressure curve fluctuates significantly, it is indicated that the shale core contains a large number of opened natural fractures or depositional beddings before fracturing, which causes the serious loss of fracturing fluid in the propagation process.

Here we use seismic images and three-dimensional waveform modelling results obtained from the NECESSArray experiment to identify a slow, continuous seismic anomaly in the mantle beneath Changbaishan. The anomaly extends from just below 660 km depth to the surface beneath Changbaishan and occurs within a gap in the stagnant subducted Pacific Plate. We propose that the anomaly represents hot and buoyant sub-lithospheric mantle that has been entrained beneath the sinking lithosphere of the Pacific Plate and is now escaping through a gap in the subducting slab. We suggest that this subduction-induced upwelling process produces decompression melting that feeds the Changbaishan volcanoes. Subductioninduced upwelling may also explain back-arc volcanism observed at other subduction zones.","[Tang, Youcai; Niu, Fenglin] China Univ Petr, State Key Lab Petr Resource & Prospecting, Beijing 102249, Peoples R China; [Tang, Youcai; Niu, Fenglin] China Univ Petr, Unconvent Nat Gas Inst, Beijing 102249, Peoples R China; [Tang, Youcai; Grand, Stephen P.] Univ Texas Austin, Jackson Sch Geosci, Austin, TX 78712 USA; [Obayashi, Masayuki; Tanaka, Satoru] Japan Agcy Marine Earth Sci & Technol, Inst Res Earth Evolut, Yokosuka, Kanagawa 2370061, Japan; [Niu, Fenglin] Rice Univ, Dept Earth Sci, Houston, TX 77005 USA; [Chen, Yongshun John; Ning, Jieyuan] Peking Univ, Inst Theoret & Appl Geophys, SESS, Beijing 100871, Peoples R China; [Kawakatsu, Hitoshi] Univ Tokyo, Earthquake Res Inst, Tokyo 1130032, Japan; [Ni, James F.] New Mexico State Univ, Dept Phys, Las Cruces, NM 88003 USA","Niu, FL (reprint author), China Univ Petr, State Key Lab Petr Resource & Prospecting, Beijing 102249, Peoples R China.","niu@rice.edu","Grand, Stephen/B-4238-2011","Obayashi, Masayuki/0000-0003-4026-2649","NSF; JSPS","We thank all the people in the NECESSArray project fOr installing and servicing the seismic array Discussimss with H.

One of the most widely used methods for suppressing random noise was f-x predictive filtering. When the subsurface structure becomes complex, this method suffered from higher prediction errors owing to the large number of different dip components that need to be predicted. We developed a novel denoising method termed f-x empirical-mode decomposition (EMD) predictive filtering. This new scheme solved the problem that makes f-x EMD ineffective with complex seismic data. Also, by making the prediction more precise, the new scheme removed the limitation of conventional f-x predictive filtering when dealing with multidip seismic profiles. In this new method, we first applied EMD to each frequency slice in the f-x domain and obtained several intrinsic mode functions (IMFs). Then, an autoregressive model was applied to the sum of the first few IMFs, which contained the high-dip-angle components, to predict the useful steeper events. Finally, the predicted events were added to the sum of the remaining IMFs. This process improved the prediction precision by using an EMD-based dip filter to reduce the dip components before f-x predictive filtering. Synthetic and real data sets demonstrated the performance of our proposed method in preserving more useful energy.","[Chen, Yangkang] Univ Texas Austin, Bur Econ Geol, John A & Katherine G Jackson Sch Geosci, Austin, TX 78712 USA; [Ma, Jitao] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing, Peoples R China","Chen, YK (reprint author), Univ Texas Austin, Bur Econ Geol, John A & Katherine G Jackson Sch Geosci, Austin, TX 78712 USA.","ykchen@utexas.edu; majitao1983@126.com","Chen, Yangkang/C-3826-2016","Chen, Yangkang/0000-0001-9843-3995",{"$nulls":3},27,66,67,4,10,"SOC EXPLORATION GEOPHYSICISTS","TULSA","8801 S YALE ST, TULSA, OK 74137 USA","0016-8033","1942-2156",null,"GEOPHYSICS","Geophysics","MAY-JUN",2014,79,3,{"$nulls":4},"V81","V91",null,"10.1190/GEO2013-0080.1",{"$nulls":3},11,"Geochemistry & Geophysics","Geochemistry & Geophysics","AK3KP","WOS:000338322900045",null,null,"Y","N","2018-01-15"]

The synergetic effect between Co3O4 and g-C3N4 plays an important role in promoting photo-generated carrier separation.

Such structures in shale samples from the Lower Cambrian strata of the Sichuan Basin of China have been investigated using X-ray diffraction, total organic carbon content (TOC) tests, porosity and permeability tests, nitrogen adsorption, and methane adsorption experiments. Fractal dimensions were obtained from the nitrogen adsorption data using the Frenkel-Halsey-Hill method. The relationships between TOC, clay minerals, pore structure parameters and fractal dimension have been investigated. Based on the physical description of the fractal surfaces, the impact of fractal dimension on adsorption capacity has also been discussed. The results showed that the shale samples had fractal geometries with fractal dimensions ranging from 2.68 to 2.83. The organic matter is a controlling factor on fractal dimension, shown by positive correlation between TOC and fractal dimension. Fractal dimension increases with increasing surface area and pore volume, and also increases with decreasing pore diameter because of the complicated pore structure. Micropores have a greater impact on fractal dimension than mesopores and macropores. A negative correlation between fractal dimension and permeability was observed, especially for shales with high TOC and micropores counts. The fractal dimension can be used to evaluate adsorption capacity. Shale samples with larger fractal dimensions have higher methane adsorption capacity. Fractal analysis leads to a better understanding of the pore structure and adsorption capacity of a shale gas reservoir. (C) 2013 Elsevier Ltd.

At a given temperature and pressure, the gas sorption capacities of organic-rich shales are primarily controlled by the organic matter richness but may be significantly influenced by the type and maturity of the organic matter, mineral composition (especially clay content), moisture content, pore volume and structure, resulting in different ratios of gas sorption capacity (GSC) to total organic carbon content for different shales. In laboratory experiments, the GSC of organic-rich shales increases with increasing pressure and decreases with increasing temperature. Under geologic conditions (assuming hydrostatic pressure gradient and constant thermal gradient), the GSC increases initially with depth due to the predominating effect of pressure, passes through a maximum, and then decreases because of the influence of increasing temperature at greater depth. This pattern of variation is quite similar to that observed for coals and is of great significance for understanding the changes in GSC of organic-rich shales over geologic time as a function of burial history. At an elevated temperature and pressure and with the presence of moisture, the gas sorption capacities of organic-rich shales are quite low. As a result, adsorption alone cannot protect sufficient gas for high-maturity organic-rich shales to be commercial gas reservoirs. Two models are proposed to predict the variation of GSC and total gas content over geologic time as a function of burial history. High contents of free gas in organic-rich shales can be preserved in relatively closed systems. Loss of free gas during postgeneration uplift and erosion may result in undersaturation (the total gas contents lower than the sorption capacity) and is the major risk for gas exploration in marine organic-rich shales in China.","[Hao, Fang; Lu, Yongchao] China Univ Geosci, Minist Educ, Key Lab Tecton & Petr Resources, Wuhan 430074, Peoples R China; [Hao, Fang; Zou, Huayao] China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing, Peoples R China","Hao, F (reprint author), China Univ Petr, State Key Lab Petr Resources & Prospecting, Beijing, Peoples R China.","haofang@cug.edu.cn; huayaozou@cup.edu.cn; yclu@cug.edu.cn",null,null,"China Geological Survey","This research was supported by China Geological Survey.

To determine if the coal tar could be refined and upgraded to produce clean transportation fuels, detailed investigation of its composition is necessary, particularly for identifying the acidic components that account for about one-quarter of the weight of the coal tar. A middle-temperature coal tar (MTCT) and its fractions were characterized by gas chromatography-mass spectrometry (GC-MS) and negative-ion electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) with different ion transmission modes for high- and low-mass ions. Analytical results of narrow distillation fractions from FT-ICR MS agreed reasonably well with those from GC-MS, although each technique has its own advantages and disadvantages. In this work, FT-ICR MS was demonstrated to be capable of characterizing small molecules of <100 Da using appropriate operation conditions, thus yielding mass distributions to compare to GC-MS results. A continuous distribution in double bond equivalent (DBE) and carbon number was observed with the distillates of increasing boiling point, while the composition of the distillation residue was much more complex than that of distillates. Acidic compounds containing 1-7 oxygen atoms were observed in the MTCT by FT-ICR MS, with O-1 and O-2 classes being dominant.

Meanwhile, fossil fuel depletion has also been identified as a future challenge. This chapter reviews the connection between these two issues and concludes that limits to availability of fossil fuels will set a limit for mankind's ability to affect the climate. However, this limit is unclear as various studies have reached quite different conclusions regarding future atmospheric CO2 concentrations caused by fossil fuel limitations. It is concluded that the current set of emission scenarios used by the IPCC and others is perforated by optimistic expectations on future fossil fuel production that are improbable or even unrealistic. The current situation, where climate models largely rely on emission scenarios detached from the reality of supply and its inherent problems are problematic. In fact, it may even mislead planners and politicians into making decisions that mitigate one problem but make the other one worse. It is important to understand that the fossil energy problem and the anthropogenic climate change problem are tightly connected and need to be treated as two interwoven challenges necessitating a holistic solution.

The crude oil and its subfractions were analyzed by negative-ion electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). The results show that neutral nitrogen and acidic heteroatom compounds in the crude oil contain 15-55 carbon atoms with double-bond equivalent (DBE) values of 1-27, containing N-1, N-2, N1O1, N1O2, N1O3, N1O4, O-1, and O-2 heteroatom classes. No molecules in the saturate fraction can be ionized by ESI. The aromatic fraction contains N-1 and N1Ox with high molecular weights but low DBE values. The resin and asphaltene fractions contain highly aromatic and acidic class species, which are enriched in oxygen- and nitrogen-containing compounds with lower molecular weights than those found in the aromatic fraction. The distribution patterns of N-1, N1O1, and O-1 class species in the resins and asphaltenes are similar. The mass spectrum of the neutral nitrogen fraction differs from those for the bulk crude oil and its SARA fractions; the neutral nitrogen fraction is enriched with N-1 and N1O1 class species. Neutral nitrogen compounds with molecular weights lower than 200 were discriminated in the FT-ICR MS spectrum under the chosen operating conditions. However, the nitrogen species detected by gas chromatography only accounted for a small amount of that found in the neutral nitrogen fractions. Some of the neutral nitrogen species were entrained in asphaltenes during the deasphalting step of sample fractionation.","[Shi, Quan; Xu, Chunming; Zhao, Suoqi; Zhang, Yahe] China Univ Petr, State Key Lab Heavy Oil Proc, Beijing 102200, Peoples R China; [Hou, Dujie] China Univ Geosci, Fac Energy Resources, Beijing 100083, Peoples R China; [Chung, Keng H.] Well Resources Inc, Edmonton, AB, Canada","Xu, CM (reprint author), China Univ Petr, State Key Lab Heavy Oil Proc, Beijing 102200, Peoples R China.","xcm@cup.edu.cn","Zhang, Yahe/E-4823-2013","Zhang, Yahe/0000-0003-2573-568X; Shi, Quan/0000-0002-1363-1237",{"$nulls":3},61,132,144,8,97,"AMER CHEMICAL SOC","WASHINGTON","1155 16TH ST, NW, WASHINGTON, DC 20036 USA","0887-0624","1520-5029",null,"ENERG FUEL","Energy Fuels","APR",2010,24,4,{"$nulls":4},2545,2553,null,"10.1021/ef901564e",{"$nulls":3},9,"Energy & Fuels; Engineering, Chemical","Energy & Fuels; Engineering","581YZ","WOS:000276563300045",null,null,"Y","N","2018-01-15"]
