Waterless hydrocarbon based grouting mortar composition and technology for selective water influx isolation in producing wells with carbonate reservoirs, and also for consolidation of isolating compositions in wells with terrigenous reservoirs are developed. High selective and isolating properties of the given grouting mortar by the example of fields of the Orenburg and Tyumen Oblasts are confirmed.
