It is designed for application in oil producing industry: upon injection to the well for oil production stimulation, water shutoff in the producing wells and for conformance control in injection wells.
This agent can be used upon mixing with fresh water and does not require special process equipment. It is prepared as a concentrate which can be diluted with fresh water to commercial concentration before application. Efficient concentration in the solution is generally selected within 3-5% 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 treat the solution without use of special process equipment.
Working solutions of sedimentation compounds are prepared in the process tanks by dilution in fresh water. Dilution time is no more than 10-15 minutes.
Hydraulic resistances created in the formation by the reaction products, prevents water flow along the washout zones, that results in changing filtration flows in the direction of low-permeability oil-saturated portions of the reservoir.
High ability to penetrate the pore space of the perforated part of the formation due to low viscosity of solution, high surface activity.
Solubility in oil.
