Paper: Conformance Control in Oil Recovery

Once primary oil recovery from a reservoir has been accomplished, secondary and enhanced oil recovery techniques have been used to further the life of the field. Some of the most commonly occurring problems encountered with these techniques are: 1. Lack of confinement to the section of interest 2. Permeability variations in the producing zone 3. Early water breakthrough due to fingering of the injection fluid through
the oil 4. Directional permeability from injection wells to producers
