Abstract: French Camp Gas Field, San Joaquin County, CA

HOFFMAN, ROBERT D.

The French Camp gas field is located in San Joaquin County, California, at the southern limits of the City of Stockton. Nearby gas fields include the large (354 BCF) Lathrop field to the southwest, Stockton field to the north, and the recently discovered Bowman Road field one-half mile to the southwest.

The field was discovered in March 1967 with the completion of the Ferguson and Bosworth "Reynolds and Carver-West" 1. Over the next four years, two additional wells were completed and three dry holes were drilled within the general field area. An additional dry hole was drilled on the north flank of the structure in l984. No further wells were drilled until late 1994, when the Bowman Road discovery was made.

The stratigraphic section of the field consists of about 3100 ft of Pliocene-Miocene nonmarine sands and shales unconformably overlying an estimated 9000 -10,000 ft of late Cretaceous marine sands and shales. Cretaceous sand bodies include the productive Starkey and Lathrop sands.

The field is located on the upthrown side and immediately south of the very large Stockton Arch reverse fault. It consists of two small areas of closure on the anticlinal trend developed on the upthrown side of the fault. Minor faulting separates productive areas of the field

Production from the field began in late 1969 and still continues from two wells. Total production to date is 7.6 BCF of 678-835 BTU gas.
