Abstract:
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 introducing a low-viscosity diversion fluid pill (LVDF) pill through the opening to create a fluidic seal therein.

Claim (Index 11):
A method comprising:\n (a) isolating a first treatment zone comprising a first opening through a wellbore and into a subterranean formation,\n wherein the first treatment zone has been previously fractured and hydrocarbons produced therefrom; \n (b) introducing a high-viscosity treatment fluid (HVTF) into the subterranean formation through the first opening, the HVTF comprising a base fluid and a gelling agent; (c) applying incrementally increased fracturing rate steps (IIFRSs) to the HVTF to create or enhance a dominate fracture, the IIFRSs each above about a fracture gradient pressure, below about a near-wellbore apparent fissure opening pressure, and below about a far-field apparent fissure opening pressure,\n wherein between each IIFRS a downhole pressure slope over time will increase, decline, or stabilize at a measured pressure slope; \n (d) evaluating the measured pressure slope to determine whether an increasing pressure slope, a stabilizing pressure slope, or a declining pressure slope exists,\n wherein if the stabilizing pressure slope or the declining pressure slop exists, a subsequent IIFRS is applied, or \n wherein if the increasing pressure slope exists, a decreased fracturing rate step (d1) is applied or a constant rate is maintained until the stabilizing pressure slope exists, followed by applying the subsequent IIFRS; \n (e) repeating one or more of steps (c) and (d) at the first treatment zone, thereby increasing a volume of the dominate fracture due to efficient dominate fracturing with generated back pressure until a maximum fracturing rate is reached; (f) introducing a low-viscosity treatment fluid (LVTF) into the subterranean formation through the first opening at the first treatment zone at the maximum fracturing rate and at a pressure above the far-field apparent fissure opening pressure to create or enhance a secondary azimuth fracture extending from the dominate fracture, the LVTF comprising a second base fluid and particulates,\n and placing the particulates into at least one of the dominate fracture and/or the secondary azimuth fracture; and \n (g) introducing a low-viscosity diversion fluid pill (LVDF pill) comprising a third base fluid and degradable particulates into the subterranean formation through the first opening at the first treatment zone to create a fluidic seal therein.
