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.
ability to prepare the solution not using special process equipment
working solutions are prepared in the process tanks by dilution in fresh water. Dilution time is no more than 10-15 minutes
R-RPMA polymers are supporting coalescence and bridging both reservoir pores, and natural cracks. This gel successfully blocks water channels with minimum reduction of permeability for oil
availability of active substances in the compound allows to change the properties of the pore space of rocks and increase permeability for hydrocarbons
high ability to penetrate the pore space of the perforated part of the formation due to low viscosity of solution, high surface activity
