Following natural oil seeps and the California petroleum industry.


“Everyone thinks of Los Angeles as the ultimate car city, but the city’s relationship with petroleum products is far more significant than just consumption.”

When struggling prospector Edward L. Doheny and his mining partner Charles A. Canfield decided to dig a well in 1892, they wisely chose a site with “tar seeps” – where natural asphalt bubbled to the surface.

Local lore says Doheny was downtown when he noticed a cart with a black substance on its wheels. He asked the driver where he had come from.

On April 20, 1892, they struck oil near present-day Dodger Stadium – and revealed the Los Angeles City oil field, which still produces tar seeps, notably at the La Brea “tar pits.” Actually comprised of asphalt, the animal-trapping pools were discovered in 1769 by a Spanish explorer, remain among the many onshore and offshore natural seeps of southern California.

The Los Angeles City oil field discovery well, completed in 1893 between Beverly Boulevard and Colton Avenue, set off California’s first oil boom by producing about 45 barrels a day.

Within two years, 80 wells were producing oil and by 1897 more than 500 wells were pumping

Doheny and Canfield became millionaires by drilling wells – using steam boilers and cable-tool technology – and selling oil to the city’s fast-growing number of industries.

Doheny also found success in Mexico, where his company in 1916 made the world’s largest oil discovery at the time. Charged with bribery in the 1920s during Wyoming’s Teapot Dome scandal, he was acquitted in 1930.

In later years Doheny became well known for his donations to foundations, churches and California universities.

Excitement surrounding the Los Angeles oil fields would also lead to the oil career of Emma A. Summers, a graduate from the New England Conservatory of Music, who moved to Los Angeles in 1893.

Emma Summers’ “genius for affairs” put her in control of the Los Angeles City oil field’s production and earned her title.

Caught up in the “oil fever” of the new petroleum industry, the former piano teacher would become known as California’s “Oil Queen.”

A 1901 newspaper article noted – “If Mrs. Emma A. Summers were less than a genius she could not, as she does today, control the Los Angeles oil markets.” Read about her in Oil Queen of California.

More than nine billion barrels of oil have been produced in the Los Angeles area. There are still more than 30,000 active wells pumping around 230 million barrels of oil a year, making Los Angeles County the second most productive oil county in California. Kern County is number one.

“The history of Los Angeles is intertwined with the use and production of gasoline and oil,” noted an article from the Center for Land Use Interpretation, Culver City, California. “Everyone thinks of Los Angeles as the ultimate car city, but the city’s relationship with petroleum products is far more significant than just consumption.”

Downtown L.A. well sites highlight field trips organized by the Center for Land Use Interpretation: “Urban Crude: The Oil Fields of the Los Angeles Basin.” 

The search for California oil went offshore in 1896 when petroleum companies built piers to reach where oil fields extended into the Pacific Ocean – thus launching the U.S. offshore industry.

North of Los Angeles in Santa Barbara County, the prolific Summerland oil field – also found near asphalt seeps – enticed Henry Williams and his associates to build a pier 300 feet out into the Pacific and mount a standard cable-tool rig on it.

Award Winning Hollywood Gusher

Edward L. Doheny discovered the Los Angeles field.

The 2007 Academy Award-winning movie “There Will Be Blood” was loosely based on Oil!, the 1927 novel by Upton Sinclair. The main character was even more loosely based on Edward Doheny.

“Although the script is based on the Upton Sinclair novel, Paul Thomas Anderson (writer-director) used only the first hundred and fifty pages for a big portion of the material,” notes one critic.

“The rest was contrived. The novel’s setting was in 1920s but it was moved to the beginning of the oil boom in California,” he reports in the Internet Movie Database.

Oil and gas museums provided advice, photographs, cable-tool rig blueprints and other materials that benefited filming. According to the director, the fake oil used for gushers was “the stuff they put in chocolate milkshakes at McDonald’s.”

Technical help came from the Kern County Museum in Bakersfield, the West Kern Oil Museum in Taft, and the Petroleum Museum in Midland, Texas, among others.

Editor’s Note – South of Los Angeles, in Orange County, the Brea Museum and Heritage Center tells the story of the Olinda Oil Well No. 1 well of 1898 – yet another important California petroleum discovery. Visit the Olinda Oil Museum and Trail at 4025 Santa Fe Road in Brea.
