Abstract Selective shutoff of undesired water influx by nonselective (fullbore) placement of treating chemicals has been successfully demonstrated in production wells of the Prudhoe Bay field. This was accomplished through: (1) careful choice of candidates with known high conductivity water influx pathways (fault, hydraulic fracture, thief), (2) placement that exploited conductivity differences without zonal isolation, and (3) use of established polymer gel chemistry with previously demonstrated ability to shut off water preferentially to oil.
