Mechanisms of Fault Activation and Casing Deformation Control During Hydraulic Fracturing in Deep Shale Gas Reservoirs

Junjie Hu, Cong Lu, Jihong Sun, Jianchun Guo et autres

Abstract Deep shale gas reservoirs (e.g., the Wufeng–Longmaxi formations) in the southern Sichuan Basin hold vast potential but face severe casing deformation due to the complex geologic conditions, including multi-directional in situ stresses, high brittleness, micro-fracture networks, and high-temperature/high-pressure environments. This study …

Research and Application of Low-Velocity Nonlinear Seepage Model for Unconventional Mixed Tight Reservoir

Li Ma, Cong Lu, Jianchun Guo, Bo Zeng et autres

Due to factors such as low porosity and permeability, thin sand body thickness, and strong interlayer heterogeneity, the fluid flow in the tight reservoir (beach-bar sandstone reservoir) exhibits obvious nonlinear seepage characteristics. Considering the time-varying physical parameters of different types of sand …
