Title: Michael M Epstein: Innovator in Subterranean Formation Technologies
Introduction
Michael M Epstein is a notable inventor based in Columbus, OH (US). He has made significant contributions to the field of subterranean formation technologies, holding a total of 3 patents. His work primarily focuses on improving methods for sealing casing perforations in wellbores and reducing the permeability of subterranean formations.
Latest Patents
One of Epstein's latest patents is titled "Use of degradable ball sealers to seal casing perforations in well." This invention involves plugging perforations in casing within a wellbore that penetrates a subterranean formation using degradable ball sealers. The ball sealer is composed of a polyester polymer that is substantially insoluble in the wellbore fluid. This polymer degrades in the presence of water at elevated temperatures, forming small molecules that are soluble in the fluid of the subterranean formation. After degradation, the flow through the perforation returns to its initial value.
Another significant patent by Epstein is "Composition for reducing the permeability of subterranean formations." This invention relates to a composition and method for reducing the permeability of subterranean formations penetrated by a wellbore. The composition comprises a wellbore fluid containing a fluid loss control agent made of a polyester polymer, which is also substantially insoluble in the wellbore fluid. Similar to his other patent, this polymer degrades in the presence of water at elevated temperatures, allowing for effective permeability reduction.
