发明名称 Complex fracturing using a straddle packer in a horizontal wellbore
摘要 A method of inducing fracture complexity within a fracturing interval of a subterranean formation is provided. The method comprises defining a stress anisotropy-altering dimension, providing a straddle-packer assembly to alter a stress anisotropy of a fracturing interval, based on defining the stress anisotropy-altering dimension, isolating a first fracturing interval of the subterranean formation with the straddle-packer assembly, inducing a fracture in the first fracturing interval, isolating a second fracturing interval of the subterranean formation with the straddle-packer assembly, inducing a fracture in the second fracturing interval, wherein fracturing the first and second fracturing intervals alters the stress anisotropy within a third fracturing interval, isolating the third fracturing interval with the straddle-packer assembly, and inducing a fracture in the third fracturing interval. The straddle-packer assembly comprises a first packer, an injection port sub-assembly above the first packer, and a second packer above the injection port sub-assembly.
