Abstract:
Disclosed are compositions containing highly water soluble CO 2 -generating compounds and their use for injection into subterranean formations for enhancing oil recovery therefrom. The subterranean formation may be an oil shale, an oil-bearing sandstone, or an oil-bearing carbonate rock for example.

Claim (Index 1):
A method for enhancing recovery from an oil-containing subterranean formation, comprising:\n injecting into an oil-containing subterranean formation a treatment solution containing at least one water soluble CO 2 -generating compound, wherein the at least one water soluble CO 2 -generating compound dissociates within the oil-containing subterranean formation to form CO 2 , and wherein (1) the oil-containing subterranean formation has a pressure of 1000 psi or greater and is selected from the group consisting of oil shales, oil-bearing sandstones, and oil-bearing carbonate rocks, (2) the weight percentage (wt %) of the at least one water soluble CO 2 -generating compound in the treatment solution does not exceed 25 wt %, and (3) the treatment solution has a temperature not exceeding about 50\u00b0 C. when injected into the oil-containing subterranean formation.
