An oil and water-containing subterranean reservoir can be heated in a manner capable of inducing an economically feasible production of oil from zones which were initially so impermeable as to be undesirably unproductive in response to injections of oil recovery fluids. Treatment zones of specified thickness are conductively heated from boreholes arranged in a specified pattern of heat-injecting and fluid-producing wells and heated to above about 600.degree. C.
