Organic matter (OM) type critically controls the hydrocarbon generation potential and organic pore development in black shales. However, maceral variation lacustrine shales its control on are not yet well understood. In this study, 15 Chang 7 Member shale samples of Yanchang Formation, Ordos Basin, were investigated with petrography, Rock-Eval pyrolysis, a scanning electron microscope to study ...

In this study, we identified the luminescent layers containing a significant amount of alginite in Upper Jurassic–Lower Cretaceous Bazhenov Formation named “the alginite-rich layers”. Lithological and geochemical methods were used to determine distinctive features these evaluate their impact on total petroleum generation potential Formation. We have shown that composition differs significantly ...

The purpose of this study is to characterize the relationship between organic material and thermal maturity during the process of evaluation of hydrocarbon potential. Samples studied include Miocene high volatile bituminous coal and coaly shale collected from outcrops and exploration wells in Hsinchu-Miaoli area, NW Taiwan, density centrifuge separated macerals, bituminous coal and anthracite f...

A total of 183 core and cutting samples from seven exploratory wells were selected to be analyzed by Rock-Eval pyrolysis. These cores have been drilled through the Lam and Meem Members of the Madbi Formation and contain the major source rocks of Yemen´s sedimentary basins. Contents of total organic carbon were measured and Rock-Eval pyrolysis was performed to evaluate the hydrocarbon potential ...

A pH-sensitive membrane for colon-specific drug delivery was synthesized by the covalent bonding of glycine on the poly(ethylene-co-vinyl alcohol) (EVAL) membrane via isocyanation of surface hydroxyl groups and subsequent conversion to activated ester. The processes of surface modification would not change the membrane structure under the observable detection sensitivity of the scanning electro...

The study of organic matter content and composition in source rocks using the methods geochemistry is an important part unconventional reservoir characterization. aim this work was structural group analysis directly rock combination with a quantitative assessment surface distribution sample by FTIR spectroscopy microscopy. We have developed new experimental procedures for semi-quantitative cont...

PURPOSE To evaluate the feasibility and effectiveness of transcatheter embolization by forcible intraarterial injection of a mixture of ethylene vinyl alcohol copolymer (EVAL) and ethanol under microballoon occlusion compared with conventional transcatheter arterial embolization methods in nontumoral swine liver. MATERIALS AND METHODS Nine swine were divided into three groups: embolization wi...

The current study is devoted to the determination and interpretation of geochemical trends reflecting hydrocarbon generation, migration accumulation in unconventional reservoirs; performed on Bazhenov shale rock formation (Western Siberia, Russia). Results are based more than 3000 Rock-Eval analyses samples from 34 wells drilled central part West Siberian petroleum basin, which characterized by...

The lacustrine shale in the second member of Kongdian Formation (Ek2) is most significant target oil exploration Cangdong Sag, Bohai Bay Basin, China. To investigate occurrence mechanisms and to reveal influencing factors mobility Ek2, a series analyses (X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), total organic carbon (TOC) analysis, Rock-Eval pyrolysis, low-t...
