Fresh water solutions of pectic materials are injected into high permeability zones in the subterranean reservoir wherein said materials upon contact with brine solutions form thick gels for the purpose of reducing the permeability of these high permeability zones thereby improving the vertical conformance efficiency of flooding operations within the reservoir.

Method for plugging high permeability zones in subterranean reservoirs

In a conventional attic oil reservoir recovery program wherein gas is injected through a well into an attic reservoir, the gas then migrating updip and displacing oil downward to the producing interval in the well wherefrom the oil is then produced, the improvement is added wherein at the completion of the gas injection step a water excluding agent is injected into the reservoir in the immediate vicinity of the well bore which prevents the formation water from restricting the flow of oil into the well bore and being produced.
