- Shutting-off of depleted reservoir intervals
- Elimination interstratal and behind-the-casing flows
- Bottom water shut-off
SUCCESSFUL APPLICATION
65-
76
TOTAL VOLUME OF REPAIR-INSULATING WORKS IN RUSSIA has increased by 94% since 2005, while the success rate of their implementation does not exceed 50-60%
CHEMICAL COMPOSITION
- A mixture of water-soluble synthetic polymers and stabilizers
ELASTIC PROPERTIES OF GEL MPS REIS-H
ESTABLISHING AN ELASTIC DURABLE GEL PROVIDES THE ESTABLISHMENT OF A RELIABLE LONG-TERM BLOCK SCREEN FOR WATER INSULATION ISOLATION
ADVANTAGES OF USAGE

- Compatible with saline water.
- Forms nanostructured gel with high strength and adhesion properties in the entire volume of the working solution
- Can be destructed by chemical methods
- Stability up to 130 °C
APPLICATION TECHNOLOGY
- Injection of the composition from 10 to 200 m3 depending on formation capacity and permeability
- Squeezing with water
- Well exposure under pressure for a period of gel formation
- Well putting on production
