ExxonMobil Production Company – Santa Ynez Unit Project

The Santa Ynez Unit produces crude oil and natural gas from Platforms Hondo, Harmony and Heritage, which are located off the California coast in the Santa Barbara Channel. The oil and gas are transported through a subsea pipeline and treated the Las Flores Canyon Oil and Gas Plant and the Pacific Offshore Pipeline Company (POPCO) Gas Plant, both located in Las Flores Canyon which is approximately 20 miles west of Santa Barbara, California.   The onshore facilities separate oil, propane, butane, sulfur products and fuel quality gas.  The natural gas is dried, treated, compressed, and sold to local utility companies.  Oil is transferred to the All American Pipeline for final processing at a refinery.
