  • Patent number: 12031413
    Abstract: A method for increasing CO2 sequestration efficiency in depleted reservoirs using a CO2 thickener is provided. The method may include the steps of introducing a thickened CO2 mixture into the depleted reservoir, where the thickened CO2 mixture comprises a mixture of CO2 and a CO2 thickener. The method may include using CO2 is in a liquid or supercritical state upon introduction into the depleted reservoir. The method may also include the step of using a CO2 thickener comprising a methyl acrylate-based copolymer, a CO2 solvent, and a solvent.

  • Patent number: 12006794
    Abstract: A method of enhancing heat transfer and energy efficiency in a geothermal reservoir includes injecting a carbonated fluid to the reservoir, injecting a first salt solution and a second salt solution into the reservoir, and increasing the temperature of the reservoir by reacting the first salt solution with the second salt solution to provide heat. The carbonated fluid injection decreases a temperature of the reservoir. The second salt solution is reactive with the first salt solution under the conditions in the reservoir after the injecting. A system of enhancing heat transfer and energy efficiency in a geothermal reservoir includes an injection system in fluid communication with an injection well. The injection system is configured to alternate the injection of the carbonated fluid and the first salt solution and second salt solution.

  • Publication number: 20240165556
    Abstract: A method for treating a basaltic formation includes providing a CO2-rich fluid in the basaltic formation, generating one or more metal ions from a metal ion source in the basaltic formation with the CO2-rich fluid, providing heat from a thermogenic reaction between a first salt solution and a second salt solution in the basaltic formation, and enhancing a reaction between the one or more metal ions and the CO2-rich fluid with the heat, thereby treating the basaltic formation. A system for treating a basaltic formation including a metal ion source includes a CO2-rich fluid that includes a source of carbon dioxide dissolved in a first aqueous fluid, a first salt solution that includes a first thermogenic agent dissolved in a second aqueous fluid, and a second salt solution that includes a second thermogenic agent dissolved in a third aqueous fluid.

  • Patent number: 11867036
    Abstract: A method for recovering hydrocarbons from a hydrocarbon bearing formation includes introducing a first solution having a first salt into the hydrocarbon bearing formation. A second solution is also introduced into the hydrocarbon bearing formation, wherein the second solution has a second salt and a foaming agent. The first salt and the second salt produces a nitrogen gas, and the nitrogen gas and the foaming agent produces a foam formed in-situ within the formation. The foam forms a foam barrier, and carbon dioxide is introduced into the formation to form a gas cap, wherein the carbon dioxide gas cap has a gas front that is separated from the hydrocarbons by the foam barrier.

  • Patent number: 11739620
    Abstract: A method to improve the efficiency of a gravity drainage CO2 gas injection process includes the steps of: (a) injecting a slug proximate to an underground reservoir, wherein the slug comprises a polymer component and an inorganic metal ion type crosslinking agent that are configured to form an in situ weak gel in the reservoir to block high permeability channels in a pay zone of the reservoir; and (b) continuously injecting CO2 gas at a top of the pay zone to form a gas cap at the top of the reservoir and to cause the gas cap to advance rapidly towards a producing well located below to provide a uniform sweep of the gas cap.

  • Patent number: 11668171
    Abstract: Described is a method for treating hydrocarbons in a reservoir. A foaming surfactant solution and a foaming gas are introduced into the upper portion of a reservoir such that barrier foam bubbles form. Then, super/critical carbon dioxide is introduced such that a CO2 cap forms. The CO2 cap is formed above a foam barrier of aggregated barrier foam bubbles positioned at an interface between hydrocarbons to be treated in the reservoir and the CO2 cap. The super/critical carbon dioxide is introduced into the reservoir at an injection rate that is greater than a pre-treatment critical gas injection rate. Hydrocarbons are recovered from a lower portion of the reservoir.
