Patent number: 11111430Abstract: Gas hydrates are formed in treatment fluid in situ within the wellbore. Foaming of the treatment fluid can occur both during the introduction of the gas treatment fluid to form hydrates and downhole near the subterranean reservoir where the heat of the reservoir will cause the gas hydrates to revert back to a gaseous state. The method involves preparing a treatment fluid comprising an aqueous base fluid, and a viscosifying agent at the surface. This treatment fluid is then introduced into the wellbore. Also, at the surface, a liquefied natural gas is pressurized and then vaporized to produce a vaporized natural gas. The vaporized natural gas is introduced into the wellbore so as to mix with the treatment fluid also being introduced. The introduction is such that gas hydrates are formed from the natural gas in the treatment fluid in situ within the wellbore.Type: GrantFiled: February 5, 2018Date of Patent: September 7, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Stanley V.
