Patent number: 12005806Abstract: Systems and methods for dynamic control of a configuration of electrical circuits are provided. An example system includes a plurality of electric power sources and a plurality of switches configured to connect and disconnect some of the electric power sources. The system may include a controller coupled to the switches. The controller may be configured to enable and disable the switches to cause a change in a configuration of the connections between the electric power sources. The electric power sources can include at least one generator and at least two batteries. The controller can be further configured to cause a change in the configuration to connect the two batteries in series to a load for discharging and connect the two batteries in parallel to the generator for recharging.Type: GrantFiled: August 13, 2021Date of Patent: June 11, 2024Assignee: Premergy, Inc.Inventors: Richard Edward Botts, Lanier M. Davenport, Andrew L. Thomas

Publication number: 20220380658Abstract: The present disclosure provides a method of treating a hydrocarbon-containing reservoir. The method involves introducing into the reservoir a surfactant composition. The surfactant composition includes an alpha olefin sulfonate or an isomerized olefin sulfonate. The alpha olefin sulfonate or the isomerized olefin sulfonate is synthesized by i) oligomerizing a monomer comprising a C3 to C6 mono-olefin to form an oligomerization product and ii) sulfonating the oligomerization product.Type: ApplicationFiled: August 31, 2020Publication date: December 1, 2022Applicant: CHEVRON ORONITE COMPANY LLCInventors: Curtis B. CAMPBELL, Andrew R. GIBBS, Andrew M. THOMAS
