ENHANCING COMPLEX FRACTURE GEOMETRY IN SUBTERRANEAN FORMATIONS, NET PRESSURE PULSING |
摘要 |
Methods including introducing a first high-viscosity treatment fluid (HVTF) into a subterranean formation through an opening and applying incrementally increased fracturing rate steps (IIFRSs) to the first HVTF to create or enhance a dominate fracture, wherein between each IIFRS applied to the first HVTF a downhole pressure slope over time will increase, decline, or stabilize at a first HVTF measured pressure slope. Evaluating the first HVTF measured pressure slope prior to applying a subsequent IIFRS to the first HVTF. Introducing a first low-viscosity treatment fluid (LVTF) through the opening to create or enhance a secondary azimuth fracture extending from the dominate fracture, and performing a first net pressure operation after the first LVTF is introduced. |
