Cymric Oil Field

The enormous South Belridge Field, one of the largest in California, begins about 1 mile (1.6 km) northeast of Cymric's northernmost extent.

The local climate is arid to semi-arid, and the predominant native groundcover is grassland and low scrub.

Some are small and disconnected, trapped by faulting and impermeable units, often at considerable depth; for example, the Phacoides pool in the Temblor Formation is at 10,145 feet (3,092 m) below ground surface, and the field operators did not find it until 1967.

The deepest well in the entire Cymric field was one drilled by the Superior Oil Company, to a depth of 12,022 feet (3,664 m), into the Point of Rocks formation, of Eocene age.

[4] The Nacirema Oil Company discovered the Cymric field in 1909, when they drilled into the huge Tulare pool with their Well No.

Unusual for San Joaquin Valley oil fields, peak production for Cymric did not occur early in the 20th century; but rather in 1996 with 11,673,403 barrels (1,855,922.8 m3).
