The United States is the heart of Occidental's oil and gas business. Our net developed and undeveloped oil and gas assets in the U.S. encompass nearly 6.7 million net acres.
Occidental's U.S. operations are organized in several regions. The largest of these is in the Permian Basin of West Texas and southeast New Mexico, where Occidental is the largest operator and the largest producer of oil. Occidental operates more active carbon dioxide (CO2) floods than any other CO2 flood operator.
In California, Occidental is the largest producer of natural gas and the largest oil and gas producer on a gross-operated barrels of oil equivalent basis. We are also the state's largest oil and gas mineral acreage holder with more than 2.3 million net acres, most of which are net fee mineral interests.
Occidental's production in the midcontinent region of the U.S. includes the Piceance Basin in western Colorado, the Williston Basin in North Dakota and fields in South Texas.
Occidental continually strives to strengthen its North America position by increasing production through strategic acquisitions and additional development in each of the company's key U.S. business areas.
