Title: Innovations by David C Berkshire
Introduction
David C Berkshire is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of well treatment technologies, holding a total of 5 patents. His work focuses on innovative methods to enhance the efficiency and effectiveness of oil extraction processes.
Latest Patents
Among his latest patents, one is titled "Treating wells with self-precipitating scale inhibitor." This invention addresses the issue of scaling in producing wells by injecting a self-reacting alkaline aqueous solution. This solution contains a pH-lowering reactant, a compound with scale-inhibiting anions, and a compound with multivalent cations. The solution precipitates a slightly soluble scale inhibitor within the reservoir, thereby inhibiting scaling. Another significant patent is "Chemical process for backsurging fluid through well casing perforations." This process chemically induces a backsurge of fluid through perforations in a well casing by injecting a solution that contains nitrogen gas-generating reactants, a reaction-retarding alkaline buffer, and a pH-reducing reactant. The rapid production of gas and heat from this reaction causes a backsurging of fluid into the wellbore.
