The process entails the use of down-hole electrodes mounted in the oil sand, a specially configured electric power unit, and facilities for injecting air and fuel into a controlled combustion zone within the area stimulated. One essential feature is creation of electrically conductive paths within the oil sand. This is accomplished in either, or both of two mutually supportive ways:electrocarbonization of a small portion of the oil present between electrodes mounted in the oil sand andinjection of electrically conductive pellets with, or in place of the sand normally injected during hydrofracing as part of the original well completion.The process has been field tested successfully for the typical largely heterogeneous oil sands found in predominantly fluvial deltaic formations. Field test was initially performed during 1979 and 1980 on a lease named Beachner-1 located in the east-central portion of Neosho County, Kansas and again in 1983 to 1985 expanded to Beachner-1 and Beachner-2. The oil reservoir at the location is shallow and generally unproductive with essentially no natural driving pressure, and natural flow is typically just 1 to 3 gallons per day per well from about twenty feet of pay sand.During the initial field test, an enhancement ratio of 4.5 to 5.4 was achieved relative to natural production, even though the field was only partially stimulated. Observed enhancement ratio during the second field test ranged from 4.6 to 10.7. And the enhancement ratio at the other more remote wells ranged from 1.8 to 3.1 giving overall enhancement ratios of 2.4 to 5.5 for all wells then on the lease at that time. Increased production was sustained for more than two years through partial stimulation of the field containing fifty wells. The neighboring leases to the south also benefitted indirectly from the stimulation on the Beachner-1 and Beachner-2 leases.P. 119^ Keywords: heatflood process, beachner-1 lease, electrofrac heatflood process, gasification, oil sand, stimulation, enhancement ratio, steam-assisted gravity drainage, spe 28620, elecfrofrac heatflood process spe 28620 Subjects: Improved and Enhanced Recovery, Unconventional and Complex Reservoirs, Thermal methods, Oil sand, oil shale, bitumen This content is only available via PDF. 1994.
