EXPERIENCE OF USING WATER-SHUTOFF COMPOUND "ISOCOM" IN THE FIELDS OF UDMURT REPUBLIC

Annotation. The process of field development becomes more complicated when faced with such problems as loss of water tightness of the production casing during the formation of water encroachment cones, the presence of behind-the-casing circulation, and the breakthrough of water injected to maintain reservoir pressure. Thus, it becomes necessary to carry out costly and time-consuming repair and insulation works. This paper deals with an opportunity to apply silicate-dispersed insulating compound "Isocom" which would enable to increase the efficiency of repair-insulation operations at the oilfields of the Udmurt Republic. Application of this waterproofing composition resulted in its high technological effectiveness, environmental safety and environmental friendliness, low price and availability. It was noted that high technological and economic indices of "Isocom" technology application point to the possibility of its mass application in the wells of "Belkamneft" named after A.A. Volkov.

Key words: field, repair-insulation works (RIW), well-workover operation (WWO), behind-the-casing circulation, water encroachment cones, viscosity, adhesion, cement stone.
