Abstract
A system for generating hydrogen and enhancing wellbore injectivity and hydrocarbon recovery includes at least one wellbore having hydrocarbons, an injector for injecting an enriched aqueous fluid into the wellbore, a fluid sensor located at a target zone of the wellbore, an ignition source located at the target zone, and a hydrogen-permeable membrane located at the target zone. A method for generating hydrogen and enhancing wellbore injectivity and hydrocarbon recovery includes dissolving oxygen into an aqueous fluid to produce an enriched aqueous fluid, injecting the enriched aqueous fluid into a wellbore comprising hydrocarbons, and measuring the concentration of oxygen of the enriched aqueous fluid. The method further includes introducing a catalyst to the target zone, adjusting a concentration of the catalyst of the enriched aqueous fluid, igniting oxygen in the enriched aqueous fluid at the target zone, and separating the produced hydrogen from the gas mixture.
