Title: The Innovative Contributions of Everett L Johnston
Introduction
Everett L Johnston is a notable inventor based in Bartlesville, OK (US). He has made significant contributions to the field of polymer science, particularly in the development of crosslinked swellable polymers. With a total of 6 patents to his name, Johnston's work has had a profound impact on various industries, including hygiene, medical arts, and petroleum production.
Latest Patents
One of Johnston's latest patents focuses on stable crosslinked water-soluble swellable polymers. This invention encompasses methods for creating these polymers and their diverse applications. The composition involves expandable polymeric microparticles that contain both labile and stable crosslinkers. When mixed with a fluid and an unreacted tertiary crosslinker, these microparticles can form a stable gel upon degradation of the labile crosslinker. A particularly important application of this technology is in petroleum production, where the expandable polymeric particles are injected into wells. The heat and/or pH conditions in the well cause the labile crosslinker to degrade, allowing the tertiary crosslinker to stabilize the gel. This process effectively diverts water to lower permeability regions, thereby enhancing oil recovery.
