Objectives of the project are to demonstrate the technical efficiency and economics of the simultaneous air and water in situ combustion process. The project is being conducted on five recently developed patterns of Cities Service Company's Bodcau Fee ''B'' lease in the Bellevue Field. The five patterns were a part of an eight-pattern expansion of Cities' combustion operations in the field. Twenty-nine producers and five injectors are included in the five patterns. Three compressors with a combined output of 20 MMCFD at 250 psig provide the air for combustion. Ignition of the five patterns was accomplished using a 30-kW, 440-volt, three-phase heater. The ignition phase began following air injectivity and falloff testing in August 1976 and was completed on September 24, 1976. Following ignition and completion of facility construction, five temperature observation wells were drilled and will be used to monitor the progress of the combustion front. Laboratory combustion tube runs and produced oil and gas analyses were made. Field tests included falloff and pulse tests. Production steadily increased from 69 BOPD in June 1976 to 420 in June 1977. Combustion has been monitored by gas analyses at producing wells. The five injection wells were converted to simultaneous air and water injection in April 1977, with initial design rates of 150 barrels per million cubic feet of air injected per well. For the first year of the project, the total cost per barrel of oil produced has been $10.03. 62 figures, 19 tables. (DLC)
