Abstract:
A process includes (a) injecting a steam composition into a subterranean location containing heavy hydrocarbons, preferably bitumen, wherein the steam composition comprises (i) steam and (ii) a hydroxyalkyl ammonium carboxylate and (b) recovering the heavy hydrocarbon from the subterranean location to above the ground. The process is preferably a cyclic steam stimulation (CSS) process, a steam assisted gravity drainage (SAGD), or a combination thereof.

Claim (Index 1):
A process comprising:\n (a) injecting a steam composition into a subterranean location containing heavy hydrocarbons, the steam composition comprising\n (i) steam \n and \n (ii) a hydroxyalkyl ammonium carboxylate having the following chemical formula: \n wherein L represents a methylene group, an alkyl ether group, an aryl group, an aryloxy group, an alkyl aryl group, or an alkyl aryloxy group, any of said groups optionally substituted with alkyl groups, branched alkyl groups, or heteroatom containing groups, R 1  is hydrogen or a linear or branched alkyl group having a primary chain length equal to or greater than 1 carbon and equal to or less than 15 carbons, and R 2 , R 3 , and R 4  are independently a hydrogen, a linear alkyl group, or a branched alkyl group with the proviso that at least one of R 2 , R 3 , and R 4  is not hydrogen and is a linear alkyl group or a branched alkyl group comprising one or more hydroxyl group and (b) recovering the heavy hydrocarbon from the subterranean location to above the ground.
