According to the data of sandstone core research, bituminous sandness has also been established in the Perm Region. Using the method of X-ray tomography, the authors evaluated the wettability of oil-saturated cores at various rock electrical resistivity ranges.It has been established that rocks are predominantly hydrophobic with resistivity more than 200 Ω·m, while, rocks practically do notfilter water with resistivity greater than 600 Ω·m. Authors developed an informative logging complex that ensured the allocation ofdifferent types of reservoir areas: hydrophilic oil-saturated, hydrophobic oil-saturated, hydrophobic bituminous (“black sandstones”)for the solving problems of efficient development of such deposits. The results were used to construct a digital geological model of the Bobrikovian horizon of the Siberian field. In this model were identified areas with a predominantly hydrophilic and hydrophobic type of reservoir in the volume of oil-saturated reservoirs.......
