And an interesting bit of history - hope their new recovery techniques are pretty good!!

"The Paris Valley Combination Thermal Drive pilot was initiated in January, 1975, to determine the technical feasibility and economics of producing petroleum from a very viscous oil reservoir under Combination Thermal Drive consisting of in-situ combustion with controlled water injection.^Producing wells are stimulated using cyclic steam.^The pilot is located in the Paris Valley oil field near San Ardo about 160 miles south of San Francisco, California.^Production is from the Ansberry formation at an average depth of 800 feet.^Production began in May, 1975 but typical oil rates were less than 3 BOPD per well.^Water production ranged from 30 to 100 BWPD per well.^The 150,000 cp crude is virtually immobile without thermal stimulation.^Current oil production is 150 BOPD and 95% of this is due to cyclic steaming.^Cyclic steaming started in June, 1975 and was expanded in July, 1976.^Individual well peak oil rates have exceeded 200 BOPD but decline quickly.^Cumulative oil production for the project is 28,191 STB or 1.6% of the OOIP within the pilot area.^Air was injected in Well 6-3 from March to September, 1976 using a rental compressor.^High casing pressures were maintained on certain wells to achieve balanced gas production at all pattern producers.^Air injectivity was good and oxygen utilization was high.^All the equipment required for the project is installed including treating facilities, steam generator and associated equipment, air compressor, produced water cleanup plant and field laboratory.^A competent field staff has been developed.^Continuous air injection into the five injectors is expected to start early in 1977."
