Thornton and Walnut Grove gas fields, Sacramento and San Joaquin Counties, California
This paper presents the history of exploration and development on the nose of the Thornton arch as specifically related to the West Thornton and Walnut Grove gas fields. These fields are in the E.-central part of the Delta area of the Sacramento basin. The Delta area is within the general boundaries described by the latitude of the city of Sacramento on the N., the Sierran foothills on the E., the Mount Diablo foothills on the S., and the eastern foothills of the Calfornia Coast Ranges on the W. A thick Tertiary and Paleocene clastic section, which is absent because of thinning and truncation in the rest of the Sacramento basin, underlies the Delta area. Gas is trapped in these rocks by combinations of folding, faulting, and abrupt facies changes. Structural traps are predominant. These fields are of interest because the mutiple producing zones represent many of the reservoir zones of the entire Sacramento Valley gas province.
