摘要
Methods of fracturing a subterranean formation that include the steps of placing a stabilizing fluid comprising a formation stabilizing agent and a degradable fluid loss controlling agent into the subterranean formation at a pressure sufficient to create or enhance at least one fracture therein, wherein the degradable fluid loss controlling agent at least partially covers a face of the fracture; placing a treatment fluid comprising proppants into at least a portion of the fracture; bridging the fluid loss controlling agent, the proppants, or both at or near the tip of the fracture to induce a tip screenout; allowing the proppants to form a proppant pack in the portion of the fracture; and allowing the degradable fluid loss controlling agent to degrade.
