Oil and Gas Heritage in Ventura County
Ventura County has been an important oil-producing region for more than a century. Historic oil fields in areas such as Ventura, Oxnard, Santa Paula, and the hills around Simi Valley helped fuel California's early economic growth. While production has declined over time and the state is transitioning toward cleaner energy, oil and natural gas remain part of the regional economy, supplying fuel, heating, and industrial feedstocks.
For Simi Valley residents, oil and gas companies are visible primarily through fuel stations, natural gas service, and regional employment. Understanding the major players helps consumers and businesses make informed decisions about fuel, energy costs, and the evolving energy landscape.
The Changing Role of Oil and Gas in California
California has adopted policies to reduce reliance on fossil fuels, including stricter environmental regulations, setback requirements for new wells near communities, and goals for zero-emission vehicles. Many oil and gas companies are responding by investing in carbon capture, renewable fuels, and lower-emission operations. Despite these changes, fuels and natural gas will remain important during the transition.

Industry Trends to Watch
Carbon capture and storage projects are gaining attention as companies seek to reduce emissions from operations. Renewable diesel and sustainable aviation fuel production is expanding as refiners adapt. Stricter regulations continue to limit new drilling in California, and many older wells are being plugged and remediated. Electric vehicle adoption is gradually reducing gasoline demand, prompting fuel retailers to add charging stations.
What This Means for Simi Valley Residents
Fuel prices in California are typically higher than the national average due to specialized fuel blends, taxes, and environmental programs. Residents can manage costs by comparing station prices, using fuel rewards programs, or transitioning to hybrid and electric vehicles. Natural gas customers can benefit from efficiency programs that lower usage and bills.
Frequently Asked Questions
Why are gas prices higher in California?
California requires a special cleaner-burning fuel blend, imposes higher fuel taxes, and operates environmental programs that add to the cost of gasoline. The state's relatively isolated refining market also means supply disruptions can quickly push prices higher compared with other parts of the country.
Is oil still produced in Ventura County?
Yes, oil production continues in Ventura County, both onshore and offshore, although output is far lower than in past decades. Operators must comply with strict state and local environmental regulations, and many older wells are being retired over time as the energy transition continues.
What is renewable natural gas?
Renewable natural gas is produced from organic waste sources such as landfills, dairies, and wastewater facilities. It can be delivered through existing pipelines and helps reduce emissions compared with conventional natural gas.
