Title: Innovations by Larry J Douglas in Petroleum Recovery
Introduction
Larry J Douglas is an accomplished inventor based in Denver, CO (US). He has made significant contributions to the field of petroleum recovery, holding 2 patents that focus on optimizing micellar systems for enhanced oil extraction. His work is instrumental in advancing techniques that improve the efficiency of petroleum recovery processes.
Latest Patents
Douglas's latest patents include innovative methods for optimizing petroleum recovery micellar systems utilizing zeta potential. This invention reveals that by varying the composition of micellar systems, the point of maximum zeta potential aligns with the point of minimum sulfonate adsorption on formation rocks. This correlation is crucial as it also corresponds with the maximum oil recovery achieved by the micellar system. Another notable patent involves designing micellar displacement systems to minimize adsorption. This method ensures that when a micellar displacement fluid interacts with reservoir rock, it produces a negative surface potential, leading to reduced surfactant adsorption and enhanced fluid integrity.
