Abstract
GROUP WATER SHUTOFF EXPERIENCE IN PRODUCING WELLS ON DEPLETED OIL ACCUMULATION U.V. ZEMTSOV 1 ”Kogalym NIPIOIL” Ltd. Improved Oil Recovery Department 15 Drouzhba Narodov Str. 628481 Kogalym Russia Problems concerning migration of associated water restraint in producing oil wells appear particularly sharply when developing accumulation with the application of intense watering. In fact injected water is percolated unproductively through the washed stratum areas. The classic problem solution found mostly often is to inject a thickened or a sealing agent into the injection wells (one or several at once at a nearby distance). In this connection the injected water filtration is
