Abstract
The method of compatibility determination of reservoir water interaction with highly mineralized displacement solutions was devised; laboratory studies on the selection of polymer type, its optimal concentration in displacement solutions to be able to maintain its rheological properties and increase the ORF at low reservoir temperatures and high mineralization of reservoir fluids were conducted. Based on the evaluation factors those determine the direction and speed of the processes occurring at the interface between solid and liquid phases, theoretical substantiation for choice of solvent to remove organic deposits formed on the surfaces of the technological equipment in the process of oil production in the extreme conditions of the North was obtained.
