Rationale – the flow of water into the well due to the circulation behind the string. Poor quality cement stone can cause aquifers to connect with oil. The presence of such channels allows water to flow from the outer annulus into the inner annulus.
The goal – elimination of the circulation behind the string, separation of reservoir layers, reducing the water content of the product.
Key point of the technology – injection of highly viscous hydrophobic stabilized water-oil emulsion (with high injection capacity), injection of Monolith cement-polymer packing composition into the outer annulus both through specialized technological holes (elimination of the lower CBS) and through the existing perforation interval (elimination of the upper CBS) preserving of reservoir properties of the pay bed
