The gas flow in shale matrix is of great research interests for optimized shale gas extraction. The gas flow in the nano-scale pore may fall in flow regimes such as viscous flow, slip flow and Knudsen diffusion. A 3-dimensional nano-scale pore network model was developed to simulate dynamic gas flow, and to describe the transient properties of flow regimes. The proposed pore network model accou...

Large gas reserves have been found in the Permian platform margin of Kaijiang-Liangping area Sichuan Basin SW China. They are assumed to be a widely developed reef–shoal reservoir. However, tight matrix reservoir cannot support high production using conventional development technology at deep subsurface. In this contribution, we analyze fractured reservoirs along strike-slip fault zones compile...

Besides biotechnology, nano-CT, the ideal technology, can also be used to observe three-dimensional nanostructures in intact cells as part of research into characteristics tight oil characteristics. There are few applications process and it is still early stage development, but advantages shown by 3D nanostructure technology very strong have applicability. Even face reservoirs with poor physica...

Pengrowth has targeted East Bodo (Alberta side) and Cosine (Saskatchewan side) for waterflood optimization and subsequent enhanced oil recovery applications. Currently, the most practical EOR technology for this heavy oil reservoir seems to be the polymer flood technology in combination with horizontal wells. Several investigators(1-4) have demonstrated the potential of the polymer flood techno...

A thermodynamic and hydrocarbon composition model based on VTFlinc software was conducted the homogenization temperature of fluid inclusions gas-to-liquid ratio, inclusions’ trapped pressure calculated. This does not require determination individual inclusions, simulation procedure is simple, result has certain reliability. The used to calculate oil in Fuyu tight reservoir Sanzhao area Songliao...

Shale oil and source rock samples of the Carboniferous Keluke Formation from well Chaiye 2 in Delingha Depression were analyzed by gas chromatography–mass spectrometry. Source rocks highly mature at generation stage with vitrinite reflectance (Ro) 1.45–1.88%. However, produced shale reservoir was characterized abundant biomarkers but low abundance diamondoid hydrocarbons estimated Ro ca. 0.78%,...

Abstract Calcite is a highly abundant mineral in the Earth’s crust and occurs as cement phase numerous siliciclastic sediments, where it often represents most reactive component when fluid percolates through rock. Hence, objective of this study to derive calcite dissolution rates on different scales reservoir sandstone using surface experiments combined with vertical scanning interferometry (VS...
