Numerical Study on Hydraulic Fracture Propagation in a Layered Continental Shale Reservoir [PDF]
Energies, 2022 The distribution of beddings varies greatly in shale reservoirs. The influence of beddings on hydraulic fracture propagation has often been studied using simplified geological models, i.e., uniformly distributed bedding models. However, the propagation processes of hydraulic fractures in shale reservoirs with complicated distributed beddings remains ...

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

Geometric Heterogeneity of Continental Shale in the Yanchang Formation, Southern Ordos Basin, China. [PDF]
Sci Rep, 2017 AbstractFavorable prospects for the exploration of shale gas have been demonstrated in the Ordos Basin, China. Outcrop and core observations indicate that there are abundant laminas in the shale strata, which exert a great influence on hydro-fracture propagation, gas storage and fluid flow.

Influence of Natural Fractures and Laminae on Fracture Propagation and Failure Mode of Continental Shale. [PDF]
Materials (Basel)Natural fractures and laminae are well-developed in continental shale, which greatly affects the fracture propagation and failure mode. Based on the natural fractures and laminae developed in the outcrops of Triassic continental shale from the southern Ordos Basin, China, four different types of shale models are constructed in this research.

N2 influences on CH4 accumulation and displacement in shale by molecular dynamics [PDF]
Scientific ReportsN2 is generally employed as a displacement agent to enhance gas recovery in shale gas-bearing reservoirs. However, the primary displacement mechanism in the subsurface still needs to be clarified due to the characteristics of shale reservoirs with low ...

Shale Tectonics in the Hyperextended Continental Margin of the Niger Delta
TectonicsAbstractBased on the interpretation of a large seismic data set, we provide a comprehensive description of the structures affecting the entire Niger Delta, from the onshore domain to the deep‐offshore. The shale‐dominated delta lies on a divergent segment of the west African passive margin.
