Low production rates of high-viscosity crudes from wells in the Kern County, California area made production enhancement through cost-effective well stimulation difficult. After a successful water fracture increased injectivity of a water-injection well in the Edison field, water fracturing was considered for the Tejon oil field near Bakersfield, California. Previous gel fractures had not been economical because of poor results and high treatment costs associated with equipment requirements. The full-length paper describes how a small-scale water-fracture treatment improved production for one well in the Tejon field. Production rates increased from 6 BOPD to 30 to 50 BOPD initially with a sustained production rate greater than 20 BOPD.
