    摘要: Method including the steps of providing a treatment fluid that comprises a base fluid and polymeric particulates and introducing the treatment fluid into a subterranean formation having a temperature above about 65° C. The polymeric particulates comprise a degradable polymer and a plasticizer and exhibit a Tg above about −15° C. When the polymeric particulates are placed into a subterranean formation having a temperature above about 65° C. they transform from rigid form to malleable form and are able to provide fluid loss, seal the rock surfaces for fluid diversion, or plug an area along the annulus of a well bore. The malleable particulates then degrade over time in the subterranean formation.

    摘要: A method for diverting fluids across a perforation tunnel in high-rate water pack operations may include providing a wellbore extending into a subterranean formation, wherein a perforation tunnel provides a fluid connection between the wellbore and the subterranean formation; providing a diverting particulate that comprises a degradable plasticized polymer coating on a particulate; placing the diverting particulate into the perforation tunnel, wherein the step of placing the diverting particulate forms a particulate pack within the subterranean formation and the perforation tunnel; allowing the degradable plasticized polymer coating to deform and fill the interstitial spaces within the particulate pack in the perforation tunnel such that the fluid conductivity between the wellbore and the subterranean formation is substantially blocked; and allowing the plasticized polymer coating to degrade over time thereby substantially restoring the fluid conductivity between the wellbore and the subterranean formation.
