Picturing California petroleum history in a family album.


Preserving a family’s photographs from Los Angeles Harbor brought insights about California maritime and petroleum heritage, including the story of Puente Oil Company.

Seeking to share the legacy of her father’s years as an employee of the Los Angeles Harbor authority, Valerie Raynor contacted the American Oil & Gas Historical Society in the summer of 2017. It wasn’t long before Raynor found a permanent home for her family’s treasured collection.

One Raynor photo of an oil company facility at San Pedro Harbor of Los Angeles tells a petroleum history story (for help preserving oil patch legacies, see Oil Families).

Raynor, a longtime resident in the Los Angeles area, decided to donate her family’s photographs to the Los Angeles Maritime Museum after talking with Mary Frances, the museum’s director.

“I felt this would be a good place to start with all the pictures,” Raynor explained, adding that In exchange for her donation of the images, which the museum will share with the the San Pedro Bay Historical Museum, the Raynor family will receive high-resolution digital copies.  

Raynor admitted she needed a quick lesson on how to scan. “I decided I should not use the excuse of ‘I can’t do this,’ when we tell our kids that that is not a good enough excuse! So, I called a friend who walked me through how to scan and send a pic.” Her family — and historians — have benefited, thanks to preservation of her father’s career.

“It’s a great way to have them preserved for future generations,” Raynor said. “The pictures will be kept in honor of my father, Paul J. Thome, who worked for the City of Los Angeles at the San Pedro Harbor in the 1960s and 1970s.

Traditional 42-gallon “bilged” wooden oil barrels from the industry’s earliest days were gradually replaced by the 55-gallon steel drum.

The San Pedro Bay Historical Society was established in 1974 by a group of residents, “seeking ways to preserve the unique harbor area so rich in history and influential in the development of Los Angeles proper, banded together in 1974,” according to the society website

Picturing Puente Oil

Although an 1865 discovery near oil seeps in Humboldt County might be considered the first California oil well, the state’s petroleum exploration industry took off following an 1876 gusher that revealed the Pico Canyon oilfield. In 1892, about 35 miles south of Pico Canyon, a former gold prospector then discovered the massive Los Angels field.

Edward Doheny and Charles Canfield discovered oil in the hills northwest of downtown Los Angeles in 1892. Their well, drilled near present-day Dodger Stadium, revealed the Los Angeles City oilfield.

As would be found at many of California’s oilfields, the area had natural oil seeps, most notably at the La Brea “tar pits.”

Doheny also opened up Orange County’s first oilfield with a successful well at Olinda in present-day Brea in 1897, explains Paul R. Spitzzeri in “Drilling for Black Gold in the Los Angeles Oil Field, 1890s.” The Puente Oil Company was a part of this southern California petroleum industry, which began in the mountains near Santa Clarita as early as 1865, Spitzzeri reported.

However, oil production and efforts to make Los Angeles’ refineries profitable had limited success for several decades. The real boom would come when gasoline for autos replaced kerosene for lamps as the most profitable refinery product. This coincided with a giant oilfield discovery at Spindletop Hill, Texas, in 1901.

By 1886, William Rowland, son of the owner of Rancho La Puente, John Rowland, and his partner William Lacy had successfully drilled several oil wells on the ranch.

The wells helped launch the Puente Oil Company in Los Angeles, one of many ventures that hoped to find oil in southern California at the turn of the century. One small enterprise with a similar name, the Puente Crude Oil Company, did not fare as well.

Old and new technologies share the harbor site as well – Nellie Bly’s 55-gallon steel drums and old 42-gallon wooden barrels; the sails and train rails with log drivers (catty men, river rats, river pigs, etc.) corralling floating pilings; and on South Seaside Avenue, the Puente Oil Company – the first to exploit southern California’s Puente Hills’ petroleum resources.

Because of its high-gravity, Puente Oil sold for up to $1.75 a barrel, while lesser grades sold at 75 cents to $1 per barrel. The company soon built a pipeline from its drilling sites to the Puente railroad depot. From Puente, tank cars (marked “P. O. Co.”) carried the oil to Los Angeles harbor. The company prospered.

In 1895, a six-year contract to supply substantial quantities of crude oil to the Chino Beet Sugar refinery prompted Puente Oil to build its own pipeline to the user, 16 miles away. Just the first year’s requirement was for 80,000 barrels of oil.

Puente Oil then built its own 800 barrel a day crude oil refinery nearby in Chino. This was before the Supreme Court’s 1911 ruling to break up the Standard Oil monopoly, so Standard bought all of the Puente Oil refinery’s output.

Dead Man’s Island and Rattlesnake Island (both now part of the largely artificial Terminal Island) were first linked in 1893. Modern dredging has changed much of the harbor’s landscape.

By 1900, Puente Oil had grown to “a total of 4,700 acres of the best light oil-producing lands in California” with 85 wells pumping a total of 20,000 barrels of oil a month. Puente Oil in 1903 merged with the Columbia Oil Producing Company (a 1898 venture of W.L. Hardison, co-founder of Union Oil Company).

“The consolidation of the Puente and Columbia companies is with one exception the largest oil deal ever consummated in Southern California, and carries as great an oil value as any deal of record,” noted the Pacific Coast Reporter. Shell Union Oil Company acquired both Columbia Oil Producing and Puente Oil in 1922.

Today, much of the Puente Oil’s former oil producing land is managed by the Puente Hills Landfill Native Habitat Preservation Authority. The Port of Los Angeles handles almost 200 million tons of freight every year.
