Abstract
Improvements in secondary recovery operations for the recovery of oil, and improvements in well drilling operations, are accomplished through the use of aqueous gels exhibiting high gel strength prepared from water and a mixture of (a) at least one cellulose ether, e.g., carboxymethyl cellulose, and (b) at least one polyacrylamide.
