Title: Petroleum systems in the Sacramento Basin, California, USA

Abstract

The Sacramento Basin, a north-trending forearc basin that contains Late Jurassic to Holocene sedimentary rocks which thicken to the south, is primarily a gas province with minor occurrences of oil, comprising four petroleum systems, two of gas and two of oil. The Dobbins-Forbes(?) gas system, which contained about 2.2 5 tcf (10{sup 12} ft{sup 3}) of recoverable gas, underlies the Winters-Domengine(?) gas system, which contained about 6.89 tcf of recoverable gas. Gas migrated laterally to the north as far as 200 km in the Dobbins-Forbes(?) system, whereas in the Winters-Domengine(?) system, gas first migrated vertically and then crossed the Midland Fault to the east for as far as 40 km. In both systems, depth of gas production is less than 3 km. On the basis of petroleum geochemistry of the oils, two unnamed oil systems have been identified. Oil recovered from cinnabar mines, a gold mine, seeps, and a few wells along the northwest flank of the basin are all similar and constitute one oil system. The provenance of this oil type is a Cretaceous source rock. The oil from the Brentwood and Livermore Oil Fields at the south end of the province, which constitute the other oil system, ismore » thought to originate from the Kreyenhagen Formation of Eocene age. By applying the petroleum-system concept and available information about the geology and geochemistry of this province, our study provides a new testable hypothesis for the origin, migration, and accumulation of petroleum in the Sacramento Basin.« less
