Hydraulic Fracture Cross-Layer Propagation in Multicyclic Sandstone: Experimental Investigation of Driving and Resisting Stress Competition for Reservoir Stimulation

Efficient stimulation of heterogeneous sandstone reservoirs requires a comprehensive understanding of cross-layer hydraulic-fracture propagation and its controlling mechanisms. Taking the Jurassic Lianggaoshan Formation in the Sichuan Basin as the geological prototype, 300 mm cubic artificial specimens containing coars...

Discrete element simulation and dimensionless parameter-based optimization of near-wellbore fracture propagation during perforation fracturing of tight sandstone.

Perforation fracturing is essential for stimulating unconventional reservoirs such as shale and tight sandstone. However, field monitoring techniques has revealed that many perforation clusters contribute little to post-fracturing production, indicating inefficient fracture initiation and limited stimulation effect. Th...
