Well Orientation Effects on Hydraulic Fracturing in Tight Sandstone: A True Triaxial Experimental Study
To clarify the controlling effects of the well deviation angle and azimuth angle on the breakdown pressure, propagation morphology, and fracture-network complexity of hydraulic fractures in tight sandstone, true triaxial hydraulic fracturing physical simulations were systematically conducted on Chang 7 Member sandstone...
