Quantitative characterization and optimization of fracability in continental shale reservoirs. [PDF]
Sci RepRecent exploration has confirmed the potential of Jurassic continental shales in the Sichuan Basin, yet hydraulic fracturing quality remains a key challenge for their commercial development. This study establishes a quantitative model to evaluate and optimize shale fracability, with application to Middle-Lower Jurassic shales in the Yuanba area.

Optimization Analysis of In-Situ Conversion and Displacement in Continental Shale Reservoirs. [PDF]
ACS OmegaIn the context of growing global energy demands and the need for efficient extraction techniques, this research, based on numerical analysis, addresses the high-energy demands of in situ conversion by introducing a two-stage development strategy. The strategy begins with an initial continuous heating stage, followed by a thermal stabilization stage. It

Water imbibition of shale and its potential influence on shale gas recovery—a comparative study of marine and continental shale formations [PDF]
Journal of Natural Gas Science and Engineering, 2016 Abstract A large volume of fracturing fluid is pumped into a well to stimulate shale formation. The water is imbibed into the reservoir during this procedure. The effect of the imbibed water on gas recovery is still in debate. In this work, we study the spontaneous imbibition of water into marine shale samples from the Sichuan Basin and continental ...

A review of commercial development of continental shale oil in China
Energy Geoscience, 2022 Continental shale oil is an important strategic supplement to the sustainable development of petroleum industry in China. Based on the thermal maturity of organic matter, most shale oil in China is medium-high or medium-low mature oil with relatively high density that is usually stored in thin layers and difficult to extract due to strong fluid flow ...

Development potential and technical strategy of continental shale oil in China
Petroleum Exploration and Development, 2020 Continental shale oil is a general term for liquid hydrocarbons and many kinds of organic matter in continental organic-rich shale series with vitrinite reflectance of more than 0.5% at buried depth of more than 300 m, and is an important type of source-rock oil and gas. Based on the evolution model of oil generation and expulsion in organic-rich shale

Advances in understanding imbibition characteristics of shale using an NMR technique: a comparative study of marine and continental shale [PDF]
Journal of Geophysics and Engineering, 2018 Studying the imbibition characteristics of shale contributes to understanding the low flowback efficiency (< 20%) and its potential effects on gas production. Previous studies have mainly focused on imbibition characteristics of marine shale, but few investigations have been conducted on continental shale to explore the microscopic imbibition mechanism.
