Title: The Innovative Contributions of Leslie Bretherick
Introduction
Leslie Bretherick is a notable inventor based in Ascot, GB. She has made significant contributions to the field of oil recovery through her innovative patents. With a total of 2 patents, her work focuses on enhancing oil recovery processes and environmental protection.
Latest Patents
Bretherick's latest patents include compositions for use in oil recovery and a method for creating an inflatable barrier for oil spills on water. The first patent involves betaines containing the morpholine nucleus, which are dissolved in sea water or formation water. The concentration of betaine ranges from 200 to 100,000 ppm, resulting in a surfactant solution that effectively displaces crude oil during enhanced oil recovery processes. This solution also includes an anionic surfactant with an ethoxylated benzene ring, which synergistically lowers the interfacial tension against oil. Notably, these betaines exhibit high tolerance towards divalent metal cations and maintain high temperature stability compared to previously proposed alternatives.
The second patent addresses the environmental challenge of oil spills. It describes an inflatable barrier designed to contain oil spills on water. This barrier consists of an air chamber and a water chamber, which, when inflated, form a figure-of-eight cross-section. A pilot air tube is attached to the air chamber to facilitate laying the barrier, ensuring it does not sink or twist before full inflation.
