Title Arrangement for recovering viscous petroleum from thick tar sand
Date 1977-05-03
Description An arrangement is provided for recovering viscous oil from a tar sand formation having a large vertical dimension including a substantially vertical lined shaft extending through the tar sand formation. A first opening is formed in the lower portion of the shaft lining and at least one lateral hole extends into the formation through the first lateral hole. A plurality of tubular members are positioned in the lateral hole to provide both a closed loop flow path for fluid flow from the shaft into and out of the hole out of contact with the formation and a separate flow path for production fluids from the hole into the shaft. A steam source is connected to the tubular members forming the closed loop flow path. A second opening is formed in the shaft lining and a steam injection conduit extends through the second opening into the formation. The steam injection conduit is connected to the steam source for injecting steam into the formation.
