Oil and Gas in the Texas Economy
Texas is the largest oil and natural gas producing state in the United States, and the industry has shaped the state's economy for more than a century. While Round Rock is not located in a major oil field, residents and businesses depend on the industry every day. Natural gas heats homes and powers many electricity generation plants on the ERCOT grid, gasoline and diesel fuel vehicles and logistics fleets, and petrochemical products appear in countless consumer goods.
The industry also supports professional jobs across Central Texas, including engineering, finance, legal, technology, and environmental services. Many energy professionals live in Round Rock and work for companies operating across the state, attracted by the city's quality of life and strong schools.
Segments of the Oil and Gas Industry
The oil and gas industry is typically divided into three segments. Upstream companies explore for and produce oil and natural gas. Midstream companies transport and store resources through pipelines and terminals. Downstream companies refine crude oil into fuels and products and distribute natural gas to homes and businesses. Each segment plays a role in delivering energy to Round Rock.
