Abstract
Official abstract text for this publication.
A hydrocarbon from a subterranean formation can be recovered by contacting the hydrocarbon with water or steam and one or more additives. The hydrocarbon can be selected from heavy or light crude oil, bitumen, an oil sand ore, a tar sand ore, and combinations thereof. The additive can be, for example, an aromatic hydrocarbon. The water or steam and the additive can be injected into the subterranean formation. Compositions or mixtures include hydrocarbons, water or steam, and additives.
First claim
Opening claim text (preview).
The claimed invention is: 1. A process for recovering a hydrocarbon from a subterranean formation comprising the steps of: (i) contacting a hydrocarbon from a subterranean formation with steam or water; (ii) contacting the hydrocarbon from the subterranean formation with one or more aromatic hydrocarbons, wherein the hydrocarbon from the subterranean formation is contacted with the steam or water and the one or more aromatic hydrocarbons inside of the subterranean formation, where…
