Polymeric microspheres as biodegradable Additives against loss of Fluid in Oil Field applications

摘要

A method for plugging a fracture in a Subterranean formation in the fracture, which involves placing a composition comprising microglobulos beads or microspheres, which are created by cross linking surface water droplets in an emulsion in water. These microspheres can form a Filter cake in the formation.The microspheres may include a Chemical Agent to be released when the microspheres are dissolved.
