Lompoc Oil Field
The Lompoc Oil Field is a large oil field in the Purisima Hills north of Lompoc, California, in Santa Barbara County. Discovered in 1903, two years after the discovery of the Orcutt Oil Field in the Solomon Hills, it is one of the oldest oil fields in northern Santa Barbara County, and one of the closest to exhaustion, reporting only of recoverable oil remaining out of its original as of the end of 2008.〔 p. 94〕 Its sole operator as of 2009 was Houston, Texas-based Plains Exploration & Production. In 2009, the proposed decommissioning and habitat restoration of the field was part of a controversial and so-far unsuccessful deal between Plains, several environmental groups, Santa Barbara County, and the State of California, to allow Plains to carry out new offshore oil drilling on the Tranquillon Ridge, in the Pacific Ocean about twenty miles (32 km) southwest of the Lompoc field.
==Setting==
The Lompoc field follows the line of the Purisima Hills, a northwest-to-southeast trending range dividing the Santa Ynez Valley on the south from the Los Alamos Valley to the north, and the field is about five miles (8 km) long by one-half to one mile (1.6 km) across. The hills are a part of the Burton Mesa region, much of which is an ecological reserve maintained by the California Department of Fish and Game. Populated places close to the field include Vandenberg Village and Lompoc to the south, Vandenberg Air Force Base to the west, and Los Alamos to the east. One public road, Harris Grade Road, traverses the field from north to south. Several access points to the field are along this road. Most of the field's productive area, and most of the oil wells, are on the southern slope of the hills. Elevations on the oil field range from around on the west to at the summit of the Purisima Hills.
Climate in the region is Mediterranean, with cool, rainy winters and dry summers during which the heat is greatly diminished by fog and northwesterly winds from the cold waters of the Pacific Ocean, which is about west of the field. Prevailing winds year-round are from the west-northwest. The north slopes of the hills contain stands of bishop pine as well as coast live oak forest; the south-facing slopes have mostly chaparral vegetation types, including coastal sage scrub.〔(Modeling vegetation pattern using digital terrain data p. 72 )〕 Fourteen inches (36 cm) of rain falls in a typical winter. Drainage on the south side of the hills is to the Santa Ynez River, and then out to the sea via Lompoc; to the north, runoff goes to San Antonio Creek, which exits to the ocean through Vandenberg Air Force Base.
A small discontiguous part of the field, the Northwest Area, is situated about a mile and a half northwest of the main part of the field, close to the main gate of Vandenberg Air Force Base. As of 2009, that area had 9 actively producing wells, as well as three used for water disposal.〔(Lompoc Field query at California Department of Conservation )〕
