Torrance's Deep Roots in Oil and Gas
Oil has shaped Torrance since the early twentieth century. The discovery of the Torrance oil field in the 1920s brought hundreds of derricks to the area, and the industry helped build the city's industrial economy. Today, Torrance is home to one of the largest refineries in Southern California and is close to a dense network of refineries, terminals, pipelines and ports in the South Bay and Harbor area. These facilities produce gasoline, diesel and jet fuel for millions of Californians and support thousands of jobs. While California is transitioning toward cleaner energy, oil and gas companies remain important to the regional economy and fuel supply. Here are the top 10 oil and gas companies relevant to Torrance.
The Role of Oil and Gas in the Region
The South Bay and Harbor area form one of the most important refining centers on the West Coast. California requires specially formulated cleaner-burning gasoline, so in-state refineries are critical for supplying the market. Natural gas is also essential for home heating, cooking, industrial processes and electricity generation. Pipelines, marine terminals and storage facilities connect these operations to the Ports of Los Angeles and Long Beach.
