Reservoir energy response mechanism during shale gas accumulation in Longmaxi Formation

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In order to explore the microscopic energy response mechanism of the shale gas accumulation process in the Longmaxi Formation, the energy balance theory is taken as the core. Based on the tectonic evolution and hydrocarbon generation history simulation, the elastic energy and gas elasticity of the Longmaxi Formation shale ...

Study on the Mechanical Properties and Fracturing Damage Process of Shale With Preexisting Fractures Under Fluid–Solid Coupling Effects

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
To investigate the influence of fractures on the hydraulic fracturing extraction of shale gas, this study conducted a fluid–solid coupling analysis of shale with preexisting fractures. Initially, the mineral composition and the distribution of microfractures and pores in the shale were analyzed using X‐ray diffraction (XRD) and argon ion scanning ...

NMR‐Based Quantitative Characterization of Water Imbibition in Deep Shale Rocks Under Different Pressures and Temperatures

Geofluids, Volume 2025, Issue 1, 2025.
Unconventional tight/shale gas reservoirs have gained significant attention in the energy sector. The importance of temperature and pressure in shale imbibition lies in their profound influence on the kinetics, rate, and ultimate amount of water uptake, which directly impacts the efficiency of gas production.

Characteristics of shale nanopore system and its internal gas flow: A case study of the lower Silurian Longmaxi Formation shale from Sichuan Basin, China

Journal of Natural Gas Geoscience, 2017
The gas flow in shale nanopores undergoes a transition from continuum-transition flow regimes to Knudsen diffusion, rather than the traditional Darcy flow, due to the dynamic properties of shale gas.

Research and Application of Personalized PDC Bits for Longmaxi Formation in Changning, Sichuan Basin

Academic Journal of Science and Technology
The Longmaxi Formation in the Changning Block of the Sichuan Basin has a large reservoir thickness and is a high-quality shale for the main shale gas bearing target layer. However, problems such as high rock strength, high drillability level, and large horizontal drilling length in the Longmaxi Formation have led to rapid failure of the drill bit and ...

Tectonic Impact on Organic Matter Enrichment in Paleozoic Marine Shales from the Yangtze Block, SW China

Journal of Marine Science and Engineering
The enrichment of organic matter in marine shale is a complex process involving tectonic–sedimentary interactions. The tectonic setting exerts critical control over sediment provenance, marine biota, and subaqueous environmental conditions in shale ...
