NOVEL METHOD FOR ENHANCING FRACTURE CONDUCTIVITY

摘要

The present invention relates to compositions and methods for enhancing fracture conductivity. One embodiment of the present invention provides a method of providing a fracturing fluid and a flowable propping composition having a hardenable external phase and an internal phase where the internal phase is immiscible with the external phase; introducing the fracturing fluid into a subterranean formation; introducing the flowable propping composition into a fracture in the subterranean formation; allowing the hardenable external phase to form a hardened external phase in the fracture in the subterranean formation; and allowing the presence of the internal phase to be reduced from the hardened external phase thereby leaving a void volume in the hardened external phase.
