Field Characterization
The reserves of the Sergeevskoye deposit are confined to the Devonian terrigenous sandstones (D-I, D-II, and D-IV), as well as in the Tournaisian stage (limestones), in the sandstones of the terrigenous sequence of the Lower Carboniferous.
The occurrence of oil in the Devonian formations is about 2 km. The deposits from the North and the West are shielded by a graben-like trough up to 130 m deep and 1 km wide, filled with mudstones (clays) of Kynov's age.
Oils of medium viscosity (up to 4.5 MPa.s), sulphurous. Gas saturation 45 m3 / t. With watering of reservoirs of 85%.
Oil production rates - 12.3-255 tons / day. The NGDU Ufaneft (LLC Bashneft-Dobycha) is being developed at the final stage.
