Abstract
In one aspect, a method of recovering hydrocarbons from a subterranean zone includes flowing carbon dioxide in a first state into the subterranean zone including hydrocarbons, wherein a density of the carbon dioxide in the first state is greater than a density of carbon dioxide in a gaseous state, and recovering at least a portion of the hydrocarbons in the subterranean zone in response to flowing carbon dioxide in the first state into the subterranean zone.
