our operations explainer: what is the permian basin?

The Permian Basin is an energy-rich depression in the earth’s crust that spans parts of West Texas and New Mexico. How rich? It accounts for nearly 40% of the oil production and 15% of the natural gas production in the United States.

At approximately 250 miles wide and 300 miles long, this shale basin is larger than the entire state of Florida. Chevron, one of the largest oil and gas producers in the region, owns approximately 2.2 million net acres in the region.

Unique rock characteristics make the Permian Basin one of the most prolific fields in the world.

Its geology enables a single well to produce oil and natural gas from several layers of rock in different geological zones. This multiplies the basin’s natural resource potential.

Advances in hydraulic fracturing and horizontal drilling technologies have accelerated production in the Permian Basin. The number of horizontal wells in the region grew from 350 in 2010 to 4,524 in 2021.

Chevron is tapping into high tech to drill more efficiently in the Permian Basin by using:

• Advanced technologies to boost our well performance.
• Predictive analytics to make decisions related to exploration strategy, resource characterization, drilling and the final stages of well construction.

Worldwide events and the growing global demand for energy access in developing countries have underscored the importance of reliable, affordable and ever-cleaner energy sources.

We plan to increase production there to 1 million barrels of oil-equivalent per day by 2025 and believe technology will help get us there.
