The relevance of the study is determined by the problem associated with the correct assessment of the saturation of low-resistivity reservoirs in the fields of the Surgut arch. According to the materials of geophysical well surveys (GIS) productive low-resistivity reservoirs are interpreted as water-saturated, due to which they are not used in further well operation. The article evaluates the factors influencing the oil saturation index (OSI) readings at one of the unique fields of Surgutsky arch, as well as testing the methodology capable of solving the problem of determining the true saturation of rocks.
