  • Patent number: 4201420
    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.
