Title: Downhole fluid injection systems, CO 2 sequestration methods, and hydrocarbon material recovery methods

Abstract

Downhole fluid injection systems are provided that can include a first well extending into a geological formation, and a fluid injector assembly located within the well. The fluid injector assembly can be configured to inject a liquid CO 2/H 2O-emulsion into the surrounding geological formation. CO 2 sequestration methods are provided that can include exposing a geological formation to a liquid CO 2/H 2O-emulsion to sequester at least a portion of the CO 2 from the emulsion within the formation. Hydrocarbon material recovery methods are provided that can include exposing a liquid CO 2/H 2O-emulsion to a geological formation having the hydrocarbon material therein. The methods can include recovering at least a portion of the hydrocarbon material from the formation.
