At the beginning of 2009 it still contained an estimated 387,000 barrels (61,500 m3) of recoverable oil out of its original 23.5 million, and had 15 wells remaining in operation.

[1] The field is long and narrow, exactly following the Oak Ridge Fault which also defines the alignment of the Santa Clara River, running from northeast to southwest.

[2] California State Route 126 parallels the field for its entire length, about one-half mile to the northwest.

Climate in the region is Mediterranean, with cool, rainy winters and warm, rainless summers, in which the heat is moderated by frequent morning coastal low clouds and fog.

Within the Ventura Basin are some of the richest agricultural fields in California, made possible by the thick alluvial topsoil left by tens of thousands of years of floods from the area's river systems.

The fault bounds the field on the southeast; many of the oil-bearing units have been deformed so as to be aligned almost vertically, especially in the lower zones.

[8] As production began its inevitable decline, Shell commenced waterflooding operations to increase reservoir pressure and dispose of produced water.

Crimson ran the field until 2002, at which time they sold their 41 remaining wells to Bentley-Simonson, who held it until April 2005, selling to Plains Exploration & Production, who operated the declining field for slightly more than a year, selling the 14 remaining active wells to their present operator, Vintage Production, in October 2006.
