RE-FRACTURING A FRACTURE STIMULATED SUBTERRANEAN FORMATION

摘要

Embodiments herein include a method comprising providing a subterranean formation having a first treatment interval comprising at least one preexisting perforation through which at least one preexisting fracture has been formed; providing a temporary sealant slurry comprising a slurry base fluid, non- degradable particulates, degradable particulates, and a stabilizing agent; placing the temporary sealant slurry into the preexisting perforation at the first treatment interval so as to at least partially seal the preexisting perforation; forming at least one new perforation; injecting a fracturing fluid comprising a fracturing base fluid and proppant particulates into the new perforation at a rate and pressure sufficient to create or enhance at least one new fracture in the formation; placing the proppant particulates into the new fracture so as to form a proppant pack therein; and degrading the degradable particulates so as to remove at least a portion of the seal in the preexisting perforation.
