The field is operated by BP; partners are ExxonMobil and ConocoPhillips Alaska. Context_2 : The Kern River Oil Field is a large oil field in Kern County in the San Joaquin Valley of California, north-northeast of Bakersfield in the lower Sierra foothills.

In terms of cumulative production to date, it is by far the largest oil field in Mexico, and one of the largest in the world. However, production has declined since 2003, falling to 408000 oilbbl/d in April 2012, making it Mexico's second most productive oil field after Ku-Maloob-Zaap.
