Buena Vista Oil Field

2 (NPR-2) is a large oil field in Kern County, San Joaquin Valley, California in the United States.

Some of the oil pools are in domes and anticlinal formations, and others are trapped in rock units due to movement of faults.

The deepest well on the field was drilled by the Honolulu Oil Corp. to a depth of 14,622 feet (4,457 m), reaching the Santos unit of Oligocene age.

These pools were discovered in 1912, peak production was in 1925, waterflooding was attempted in the 1960s, and with most of the oil having been removed, today most operations have ceased.

The Main Area of the Buena Vista Oil Field is still active, with enhanced recovery technologies such as gas injection still continuing.

[3] Most of the oil produced from the Buena Vista field is medium crude, with specific gravity of approximately 18 to 36 API.
