Isolation of reservoirs and assessment of saturation in cases of water encroachment

At the moment, almost all Mangyshlak fields have depleted reserves and an increase in water cut in the product, at this stage of field development, the problem of estimating reservoir parameters is becoming relevant. The reasons are the texture-structural, facies and lithological-petrophysical features of reservoirs of productive horizons of the field. In the future, it is planned to take samples in all new wells in order to determine the component composition of water for a reliable assessment of the current oil saturation, as well as constructing a mineralization map by area and horizons and reinterpreting well logging materials, conducting perforating and blasting operations for all wells.
