California’s history is often told through gold rushes and Hollywood dreams, but that leaves out another force that shaped the state just as much: oil. “Black gold” helped turn SoCal into an industrial and suburban powerhouse in the early 20th century, fueling roads, aviation, and the rapid expansion of Los Angeles.
Among the many fields that defined this era, none is more significant than the Inglewood Oil Field, hidden in plain sight in the Baldwin Hills area. Today, it stands as the largest urban oil field in the United States, and it’s now approaching its final chapter, with a full shutdown scheduled by 2030.
The history of the Inglewood Oil Field
Discovered in 1924, the Inglewood Oil Field quickly became one of the state’s most important petroleum sites. Development and production began the same year, when the Los Angeles Basin was still transitioning from agricultural land into sprawling urban neighborhoods.
Spanning roughly 1,000 acres, the field grew into the largest contiguous urban oil field in the country and the second-most productive in the Los Angeles Basin. Over its century-long life, more than 1,600 wells have been drilled across the site.
In total, the field has produced around 400 million barrels of oil since its discovery, making it a major contributor to regional energy supply and local economic development throughout the 20th century.
But as production declined and environmental concerns mounted, its role shifted from economic engine to controversial relic embedded within dense residential communities. The end is now effectively set in law: California legislation requires low-producing wells to cease operations by 2027 and mandates the full plugging and shutdown of all wells by the end of 2030, as reported by the L.A. Times.
What comes next for the site remains unresolved (with competing visions ranging from public parkland to housing development) but its era as an active oil field is nearing its definitive close.
