摘要： System and methods of controlling diversion for stimulation treatments in real time are provided. Input parameters are determined for a stimulation treatment being performed along a wellbore within a subsurface formation. The input parameters include selected treatment design parameters and formation parameters. A step-down analysis is performed to identify friction components of a total fracture entry friction affecting near-wellbore pressure loss during the stimulation treatment. Efficiency parameters are determined for a diversion phase of the stimulation treatment to be performed along a portion of the wellbore, based on the input parameters and the friction components. An amount of diverter to be injected during the diversion phase of the stimulation treatment is calculated based at least partly on the efficiency parameters. The diversion phase of the stimulation treatment is performed by injecting the calculated amount of diverter into the subsurface formation via perforations along the portion of the wellbore.

摘要： A method of treating a subterranean formation includes combining self-degrading particles with a carrier fluid, placing the self-degrading particles and the carrier fluid into a zone in a formation, said zone comprising fractures, allowing the self-degrading materials to penetrate and plug off the connection to existing fractures and to bridge off fracture propagation near the wellbore, and initiating a re-fracture treatment comprising re-fracture fluids and proppant materials prior to the degradation of the self-degrading particles.
