DEGRADABLE FLUID SEALING COMPOSITIONS INCORPORATING NON-DEGRADABLE MICROPARTICULATES AND METHODS FOR USE THEREOF

摘要

It can sometimes be desirable to form a temporary fluid seal in a subterranean formation in conjunction with performing various subterranean operations. Methods for forming a temporary fluid seal in a subterranean formation can comprise: providing a sealing composition that comprises a plurality of degradable particulates and a plurality of water-insoluble microparticulates; introducing the sealing composition into a subterranean formation; and forming a degradable fluid seal with the sealing composition in the subterranean formation, the water-insoluble microparticulates being substantially non-degradable. The temporary fluid seal can block or divert fluid flow in the subterranean formation.
