Abstract (en)
A method of producing hydrocarbon material from a layer of oil sand located in an earth formation, the layer of oil sand having a thickness and extending in an extension direction for more than its thickness, the method comprising creating a borehole arrangement in the earth formation, including a production borehole having a production borehole section extending in a production borehole direction, and a refill borehole having a refill borehole section extending in a refill borehole direction, wherein both the production and the refill borehole directions are deviating less than 45 degrees from the extension direction; creating a cavity in the layer of oil sand, the cavity being in fluid communication with the production borehole section; extending the cavity by operating fluid jetting means to jet a stream of fluid against a wall of the cavity, to obtain a slurry comprising fluid, hydrocarbon material, and sand; withdrawing the slurry from the cavity via the production borehole to a processing facility for processing the slurry; and injecting refill material into the cavity via the refill borehole section, wherein the refill borehole section extends below the production borehole section.
