  • Method of mining an oil-bearing bed with bottom water
    Patent number: 4379592
    Abstract: A method of mining an oil-bearing bed with bottom water, wherein a plurality of underground workings and at least one working gallery are arranged. Inlet and recovery wells are drilled from the gallery. A heat carrier is force-fed into the oil-bearing bed for heating the latter through the inlet wells. Oil is extracted from the recovery wells to the working gallery and delivered via the workings to the ground surface. While so doing, additional wells are drilled from the working gallery in the water-bearing portion of the bed in the zone of oil contact with bottom water and, simultaneously with the injection of the heat carrier into the inlet wells and extraction of oil from the recovery wells, water is extracted through the additional wells.
