Small Beginnings

Macpherson’s story begins in 1959, when Don Macpherson Sr., left Pauley Petroleum to become an independent oil producer. His first investment was in the Citronelle Oil Field in Mobile County, Alabama, a legacy asset the company still owns today.

In 1973, Don Macpherson Sr. and his son, Don Macpherson Jr., purchased a series of leases in the Round Mountain oil field, in Kern County, California. Their plan was to utilize new technologies to restart production in older fields. Discovery of oil in Kern County in 1899 led to the eventual drilling of the Round Mountain oil field discovery well by the Elbe Oil Land Development Company in 1927. The field was developed quickly and production peaked in 1938 with more than 10,000 barrels produced per day. Production declined steadily after WWII, and in the 1960s production was down to less than 2,000 barrels per day.

21st Century Energy Producers

In 1981, the Macphersons organized the company as Macpherson Oil Company LLC, a California corporation, and began deploying new innovations to develop the north portion of the Round Mountain oil field. Macpherson’s operations continued to grow, by securing the southern portion of the field in 1986 from Shell, and the center portion in 1992, from Texaco.

Today, the Macpherson brand encompasses our diverse operations with numerous partnerships and joint ventures in renewable and traditional energy. Macpherson is affiliated with Macpherson Energy Corporation, Macpherson Oil Company LLC, Macpherson Power Company, Macpherson Green Power, and Macpherson Land. Macpherson is currently the 8th largest producer of onshore oil in California, with our principal operations occurring in the Round Mountain oil field, with smaller operations in the Sharktooth, Midway Sunset, and Mt. Poso oil fields.

With approximately 150 full-time employees and contractors in Bakersfield and Santa Monica, Macpherson continues to thrive and develop new and innovative methods of production.

Looking to the Future

In 2010, Macpherson partnered with DTE Energy Services to convert its cogeneration plant into renewable energy when it converted the once coal-powered Mt. Poso Cogeneration Plant into a fully renewable plant running 100% on biomass fuel.

As California’s energy landscape continues to evolve and establish new milestones for renewable energy production, Macpherson remains committed to exploring sustainable methods of production and diversifying our energy portfolio to meet our state’s energy needs now and into the future.
