A TECHNIQUE FOR FORMATION OIL AND GAS SATURATION CONTROL IN CASED WELLS
A technique for paying formations oil and gas saturation control in production wells has been described. Its physical principles have been given. The essence of the technique consists in measuring potentials along the casing string generatrix with the help of different-length normal devices in cased boreholes. From the measurements, different problems in formation oil and gas saturation control can be solved.
