Thermoaugmentation of oil production from subterranean reservoirs
Patent
·
OSTI ID:6985081
A method is described for recovering oil from gas- permeable, subterranean reservoirs by steam soaking a reservoir interval having a permeability conducive to gravity drainage. The interval is penetrated by a borehole which is then cased and a radially-extending, disk-shaped, heat-directing impermeable barrier is formed in the central portion of the interval. Steam is then injected into the interval below the barrier until a steam zone extends beyond and above the rim of the barrier. The well is backflowed and effluent fluid is recovered. (12 claims)
