Field study - Steinle Ranch, an intermediate depth oil field, shows significant benefit from bauxite proppants
The Steinle Ranch field initially was developed in the mid-1970s. Wells were drilled, cased, perforated, and treated by chemical injection with lease-crude or condensate carriers to restore oil saturation to the formation, which is suspected to be hydrophobic. Stimulation by hydraulic fracturing of 4 wells was attempted from 1975 through 1977 with mixed results and no particular success. These treatments used sand and glass beads for proppant. A fifth hydraulic fracture treatment, in which sintered bauxite was used as the proppant was very successful. As a result, all wells in the field have been fractured. This program, in a mature field in late stages of depletion, at intermediate depth (10,600 ft), has been very successful; ca 940,000 bbl of additional reserves have resulted for a total cost of ca $2,000,000, a return on investment of 9.4:1. Comparing these reserves to estimated reserves if the wells had been propped with sand shows a 23:1 return by the incremental reserves on the incremental cost of the bauxite.
