POLYMERIC MICROSPHERES AS DEGRADABLE FLUID LOSS ADDITIVES IN OILFIELD APPLICATIONS |
摘要 |
A method of plugging a fracture in a subterranean formation which includes placing into the fracture a composition comprising microspheres or microbeads, wherein the microspheres are created by surface crosslinking of droplets in a water-in-water emulsion. Such microspheres may form a filter cake in the formation. The microspheres may include a chemical agent to be released when the microspheres dissolve. |
