Surfactant-polymer flooding in development of oil reservoirs in carbonate devonian collectors of the Pripyat trough under conditions of high-mineralized brines
Abstract
The article provides a detailed description of the process of selecting objects for implementing the surfactantpolymer (SP) flooding technology in the Pripyat trough oil fields. The selection process involves choosing the optimal SP composition to enhance oil recovery efficiency at the selected site. The article presents the results of conducting filtration experiments. The work comprises systematic research on the petrophysical properties of hydrocarbon reservoirs in the Pripyat trough, the chemical structure of oil, followed by an analysis of the stability of the dispersion system and the probability of solid phase formation. The study also includes the selection and optimization of surfactants and polymers, with subsequent testing of the chosen SP composition on core models of the reservoir
