Herein is given the list of developed by BeINIPIneft polymer and mineral-polymer water-based compositions, designed for enhanced recovery from carbonate formations of Belarusian oil fields, developed using flooding method. The formations агг characterized by structural heterogeneity, higher temperatures (uр to 110°С) and water salinity (uр to 300 g/l), presence of calcium chloride and magnesium chloride in high concentrations. The results of laboratory studies of compositions in static and dynamic conditions were systemized. In particular, reological behavior of compositions under temperatures simulating surface and formation conditions, compatibility with formation fluids, thermal stability, capability to create filtration resistance to water flow in high-porous environments, etc. were studied. We show the data speaking for high efficiency of developed compositions implemented in the process of EOR operations on the oil fields operated by Production Association «Belorusneft». Some of the compositions are adapted to geological conditions of high-temperature oi1 deposits of Venezuela, operated by JV «Petrolera BieloVenezolana».
