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.

Abstract: The method of thermal-mine recovery of oil and fluent bitumens or kerogens includes providing a system of mine workings above an oil-bearing formation and drilling from these workings and from the ground surface a series of injection wells into the oil-bearing formation. An operation gallery is provided within the oil-bearing formation, from which a system of horizontal and inclined recovery wells is drilled. Then a heat carrier is positively injected into the oil-bearing formation to heat it to a temperature whereat the oil attains the required fluidity within the formation. Then a fluid is charged into the formation to force the oil from the oil-bearing formation into the horizontal and inclined recovery wells, toward the operation gallery, from which the oil is directed to the ground surface.

Abstract: A method of oil recovery by thermal mining from oil deposit sections into which the mine field is divided, according to which a plurality of underground workings are provided ensuring a successive recovery of oil from the mine field sections. The plurality of underground workings include intake and development wells. Thereupon, an overall mine ventilation system is set up ensuring the ventilation of the workings. Prior to the supply of heating medium to the development wells, the flow of heating medium is throttled. Then, the throttled heating medium flow is force-fed via pipes into the development wells for heating the oil bed to the temperature at which oil assumes the required fluidity in the oil bed. A fluid medium is then force-fed to the intake wells to force oil from the oil bed into the development wells and pump it up to the surface.
