Abstract:
Methods including introducing a high-viscosity treatment fluid into a subterranean formation through an opening and applying incrementally increased fracturing rate steps (IIFRSs) to create or enhance a dominate fracture, wherein between each IIFRS a downhole pressure slope over time will increase, decline, or stabilize at a HVTF measured pressure slope. Further evaluating the HVTF measured pressure slope prior to applying a subsequent IIFRS. Performing a particulate sequence transport operation with a first, second, and third low-viscosity treatment fluid (LVTF), wherein the LVTFs collectively create or enhance at least one near-wellbore secondary azimuth fracture and at least one far-field secondary azimuth fracture extending from the dominate fracture, and further propping the dominate fracture, near-wellbore, and far-field secondary azimuth fractures with the particulates.
