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...
