Sacramento Basin has passed the halfway mark
Over half the gas in California's Sacramento Basin has been discovered. Future exploration will probably center in the Delta and N. Sacramento areas, with continued lesser amounts of exploration in the Suisun and N. San Joaquin areas. The author feels that more discoveries of smaller size, but taken together, of greater cumulative production, will be made in the Delta area than in the other areas. These will primarily be found on fault traps and gorge structures. Potential for fewer, but larger fields does exist in the N. Sacramento Basin where possible Forbes Upper Cretaceous sand stratigraphic traps remain to be found, and in the N. San Joaquin Basin, where possible anticlinal closure on westerly plunging noses may contain traps. The Sacramento Basin occupies the N. portion of the Great Valley of California. Its boundaries and descriptions are given. The main regional features of the N. San Joaquin areas are typical of the Sacramento Basin, a homoclinal, steeply dipping W. flank, a regional syncline lying close to the W. side, and a broad, westerly dipping E. side shelf area, all trending northwest-southeast. The Delta area, the Suisun area, and the N. Sacramento area are illustrated and described.
