Abstract: A method of mining an oil deposit, wherein a plurality of underground workings with inlet and recovery galleries are provided in an oil-bearing bed. From the inlet galleries inlet wells are drilled, and from the recovery galleries--recovery wells. A heat carrier is supplied through the recovery wells to the oil-bearing bed and oil is extracted from the recovery wells. In so doing, each inlet gallery is arranged in the bed between two recovery galleries and near the faces of the recovery wells, while the inlet and recovery wells in the oil-bearing bed portions between the inlet and recovery galleries are drilled towards each other such that they should alternate to envelop the oil-bearing bed in a uniform network of wells.

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.
