  • COMPLETION FLUID
    Publication number: 20150354298
    Abstract: An aqueous well completion/workover fluid, including a surfactant, at least one salt and an alkaline material, wherein the surfactant comprises a mixture of a phosphate ester and a non ionic ethoxylated alcohol, wherein the fluid has a pH between 6 and 8, and wherein the fluid generates an interfacial tension with crude oil of less than or equal to 1 dyne/cm. The fluid is not harmful to a formation if it penetrates the formation, and further exhibits an excellent detergency which can be beneficial as well.
    Type: Application
    Filed: May 29, 2015

  • Reversible gelling system and method using same during well treatments
    Patent number: 7994100
    Abstract: An all-oil reversible gelling system includes a polymer, a crosslinker, a gel accelerator, and an oxidant, wherein temperature activates the crosslinker so as to cause the system to form a gel, and the oxidant subsequently decomposes the gel. This gel is designed to seal temporarily portions of oil-producing or water or gas injecting subterranean formations.
