ABSTRACT:
A method for minimizing well recompletions in a multiple zone hydrocarbonaceous fluid containing formation. A steam flooding enhanced oil recovery (EOR) is conducted in the upper zone of said formation via fluidly communicating injector and producer wells which penetrate the upper and lower zones. The wells are unperforated and do not communicate with each other in the lower zone. Thereafter, a temperature activated gellable composition is injected into the upper zone where it forms a solid gel. Afterwards, both wells are perforated so as to fluidly communicate with each other in the lower productive interval. Subsequently, a steam-flooding EOR operation is conducted in the lower level and hydrocarbonaceous fluids are removed therefrom. Polymers utilized in the gellable composition include polyvinyl alcohol and polyacrylamide cross-linked with phenol and an aldehyde producing compound sufficient to form a phenolic resin in situ.
