Successful fireflooding of the Bellevue field
The Bellevue field, Bossier Parish, Louisiana was discovered in 1921 and is a dome-type structure that covers about 1,000 productive acres. The Upper Cretaceous Nacatoch Sand is the main producing zone and is 300 to 400 ft deep, averaging 60 ft thick. It is very porous, permeable, and unconsolidated with streaks of fossiliferous lime and sandy shale. Early wells flowed as much as 1,000 bpd, but later development wells were completed with pumping potentials as low as 5 bpd. After the success of Getty Oil Co.'s thermal recovery test in 1963. Cities Service Oil Co. developed a pilot thermal recovery project for the Bellevue field. The technique chosen was in situ combustion. Size of the pilot was dictated by a model study which indicated that a 2-1/2-acre inverted 9-spot pattern should be used. Four of these patterns were developed, resulting in 4 air injection wells being surrounded by 21 producing wells in a 10-acre area. How the wells were drilled and the completion of each are described. The production facilities, compressors, ignition, temperature observation, production problems, fireflood performance, water injection, and the expansion program are described.
