ABSTRACT:
To reduce the production of water from a subsurface hydrocarbon-bearing interval of a formation the producing interval of the formation is treated with an aqueous solution or sol of a high molecular weight, water soluble polyacrylamide (PAM). The polymer which is absorbed in the formation is crosslinked in situ, e.g. by subsequently flushing the formation with a crosslinking solution.
