Abstract
A hydrocarbon reservoir is treated with heat to induce gasification, water-gas shift, and/or aquathermolysis reactions to generate gases including hydrogen. The hydrogen alone is produced to the surface by using hydrogen-only membranes in the production wells.
Claims11
A method for producing hydrogen from a petroleum reservoir, the method comprising:
- a. providing a well from surface to the reservoir;
- b. locating in the well at least one hydrogen-permeable membrane;
- c. heating the reservoir to facilitate at least one of gasification, water-gas shift, and aquathermolysis reactions to occur between petroleum hydrocarbons and water within the reservoir to generate a gas stream comprising hydrogen;
- and
- d. allowing the gas stream to enter the well and engage the at least one hydrogen-permeable membrane, such that the at least one hydrogen-permeable membrane permits passage of only the hydrogen in the gas stream to the surface.
