| Characteristics of water influx into reservoirs and wells in the Mordovo-Karmalsky Field in Tatarstan have been investigated. Water isolation operations using polyacrylamide (PAA)”Accotrol S621” were carried out in seven wells. PAA water solutions were able to block channels of water influx. The costs of treatment with polymer were relatively small, however, its wide use is limited by the bottom-hole zone temperature. |
