METHODS FOR GENERATING HIGHLY CONDUCTIVE CHANNELS IN PROPPED FRACTURES |
摘要 |
Methods of forming conductive channels in a subterranean formation including providing a subterranean formation having a threshold fracture gradient; introducing a fracturing fluid at a rate above the threshold fracture gradient so as to enhance or create at least one fracture in the subterranean formation; introducing a proppant slurry into the at least one fracture at a rate above the threshold fracture gradient so as to propagate the at least one fracture and deposit the proppant slurry therein; wherein the proppant slurry comprises a base fluid and proppant particulates; injecting a substantially proppant-free resilient viscous fluid into the proppant slurry deposited in the at least one fracture at a rate below the threshold fracture gradient so as to generate a continuous channel within the proppant slurry; setting the proppant slurry; and removing the substantially proppant-free resilient viscous fluid from the at least one fracture in the subterranean formation. |
