The Oxnard Oil Field is a large and currently productive oil field in and adjacent to the city of Oxnard, in Ventura County, California in the United States. Its conventional oil reserves are close to exhaustion, with only an estimated one percent of the original oil recoverable with current technology remaining: 434,000 barrels (69,000 m3) out of an original 43.5 million.

As of the beginning of 2009, there were 34 active wells on the field. Данное издание представляет собой компиляцию сведений,...
