Denverton Creek Gas Field, Solano County, California

Robert G. Lindblom, John B. Jacobson

The Denverton Creek gas field is located in Solano County, California, 40 mi northeast of San Francisco on the west side of the Sacramento Valley. The field was discovered in 1966 by the Mobil Oil Corporation Trojan Powder 1 well from a sand of Paleocene age within the Martinez channel. During 1967 and 1968, new pool discoveries were made in other Paleocene sands. Commercial gas deliveries began in March 1967 and ceased in 1971, and the field was abandoned in 1973 with a cumulative production of 712 million ft3 of gas from three wells.

Increases in natural gas prices during the middle and late 1970s, coupled with sound geological concepts supported by improved seismic data, led to a number of discoveries in the valley. Included in this effort was reestablishment of production at Denverton Creek in 1977 by new drilling. Chevron USA, in joint ventures with Cities Service and Channel Exploration, has drilled nine wells in the field, which developed two new pool discoveries. In 1986, the field produced 5 bcf of gas from 11 wells.

Gas entrapment in the Denverton Creek field is caused by a number of anomalies, including sand pinch-out, faulting, and truncations by unconformities and the Martinez channel. Although these types of entrapping mechanisms are found in other fields in the Sacramento Valley, the Denverton Creek field is unique in that all are present in one producing area.
