Title: Geologic conversion of carbon dioxide to hydrocarbons

Abstract

A carbon dioxide to hydrocarbon conversion device and method are disclosed. A partially produced hydrocarbon subterranean reservoir comprising residual hydrocarbons is provided. A carbon dioxide source is provided, positioned on a surface proximate to the reservoir. A surface mounted high-pressure fluid injector system connecting the carbon dioxide source and the reservoir is provided. A backflow preventer is disposed in-line between the injector system and the reservoir. The injector system injects a catalyst-free feed stream, comprising carbon dioxide, into the reservoir up to an operating pressure. The backflow preventer maintains the operating pressure in the reservoir and sequesters the feed stream in the reservoir. The sequestered carbon dioxide reacts with water and at least a portion of the residual hydrocarbons over a time period to produce additional hydrocarbons. The water is present in the reservoir, provided by the feed stream, or both. The additional hydrocarbons are recovered after the time period.
