Abstract:
Improved solutions are proposed for an oil recovery process in which oil is displaced by a viscous alkaline aqueous solution. The improved aqueous alkaline solution contains a water-thickening partially hydrolyzed polyacrylamide polymer and a stabilizer consisting essentially of a 2-mercaptobenzothiazole in the presence of a sulfur-containing oxygen scavenger. A readily oxidizable alcohol or glycol may also be included.

Abstract:
An oil recovery process in which oil is displaced by a viscous alkaline aqueous solution is improved by using such an aqueous alkaline solution containing a water-thickening polymer partially hydrolyzed polyacrylamide polymer and a stabilizer consisting essentially of a 2-mercaptobenzothiazole in the presence of a sulfur-containing oxygen scavenger. A readily oxidizable alcohol or glycol may also be included.
