Publication number: 20130248188Abstract: An aqueous viscoelastic solution for use in a modified water alternating gas (WAG) hydrocarbon production method includes a viscoelastic surfactant and a salt in an aqueous base solution. A modified water alternating gas (WAG) method for producing hydrocarbons from a hydrocarbon-bearing formation includes the step of introducing the aqueous viscoelastic solution into the hydrocarbon-bearing formation. The method also includes the step of introducing a service gas into the hydrocarbon-bearing formation. The aqueous viscoelastic solution and the service gas are introduced separately and sequentially into the hydrocarbon-bearing formation. The hydrocarbon-bearing formation produces a production fluid in response to each introduction. The production fluid contains both water and hydrocarbons.Type: ApplicationFiled: March 22, 2013Publication date: September 26, 2013Applicant: Saudi Arabian Oil CompanyInventors: Fawaz M.
