- Possibility of destruction by chemical methods
Injection Volume
The volume of the injected polymer slurry averages between 1 and 2 m3
Equipment
- Pump truck
- Container for suspension preparation;
- Container for hydrocarbon solvent
- Container for water
- Equipment to tie the well reinforcement
Application Technology
When performing the work, parallel or sequential delivery of components to the isolation zone is applied
