  • Reversible Mechanically Triggered Nanosilica Gels
    Publication number: 20230118725
    Abstract: A reversible gel composition including nanosilica and polyethylene oxide, the nanosilica and polyethylene oxide present at concentrations operable to allow for the reversible gel composition to be a flowable liquid at pH greater than about 8 and operable to allow for the reversible gel composition to be a substantially solid gel at pH less than about 8.
    Type: Application
    Filed: December 15, 2022
    Publication date: April 20, 2023
    Applicant: Saudi Arabian Oil Company
    Inventors: Peter Boul, Abeer Mohammad Al-Olayan, Diana Rasner

  • Reversible aminal gel compositions, methods, and use
    Patent number: 11230658
    Abstract: A well treatment composition for use in a hydrocarbon-bearing reservoir comprising a reversible aminal gel composition. The reversible aminal gel composition includes a liquid precursor composition. The liquid precursor composition is operable to remain in a liquid state at about room temperature. The liquid precursor composition comprises an organic amine composition; an aldehyde composition; and a polar aprotic organic solvent. The liquid precursor composition transitions from the liquid state to a gel state responsive to an increase in temperature in the hydrocarbon-bearing reservoir.
    Type: Grant

  • Reversible aminal gel compositions, methods, and use
    Patent number: 10662362
    Abstract: A well treatment composition for use in a hydrocarbon-bearing reservoir, optionally as a kill pill, and comprising a reversible aminal gel composition. The reversible aminal gel composition includes a liquid precursor composition. The liquid precursor composition is operable to remain in a liquid state at about room temperature. The liquid precursor composition comprises an organic amine composition; an aldehyde composition; a polar aprotic organic solvent; and a metal salt composition. The liquid precursor composition transitions from the liquid state to a gel state responsive to an increase in temperature in the hydrocarbon-bearing reservoir.
