Method and composition for enhancing coverage and displacement of treatment fluids into subterranean formations

摘要

A method of injecting a treatment fluid into a portion of a subterranean formation, comprising providing a treatment fluid having a viscosity; determining the breakdown pressure of the portion of the subterranean formation; calculating the maximum sustainable flow rate for the treatment fluid; and, injecting the treatment fluid into the portion of the subterranean formation at a flow rate less than or equal to the maximum sustainable flow rate for the treatment fluid. A method of injecting a treatment fluid into a portion of a subterranean formation, comprising providing a treatment fluid having a viscosity; determining the breakdown pressure of the portion of the subterranean formation; calculating the maximum allowable treatment fluid viscosity; adjusting the viscosity of the treatment fluid to a viscosity less than or equal to the maximum allowable treatment fluid viscosity; and injecting the treatment fluid into the subterranean formation at the selected treatment fluid flow rate.
