It was developed for application as water soluble agent designed for bottomhole treatment for producing wells with the purpose of reservoir properties modifying in respect of relative permeability changing – increasing relative permeability for hydrocarbons and reducing relative permeability for water, is used for water inflow shutoff along washed out interlayers in the reservoir.

This agent is used upon mixing with water solutions and does not require special process equipment. It is prepared as a concentrate, which may be diluted by 2-5% KCl solution or other compatible treatment liquid before use and shall be injected into the reservoir at the injection rates and treatment pressures that do not exceed hydraulic fracturing pressures. Efficient concentration in the solution is generally selected within 2-10% range in volume, depending on the required result, which affected by the factors like: formation water salinity, porosity & permeability properties of the reservoir rocks, treatment volume.
