A native of Bessemer, Alabama, Vicki Hollub has devoted her 35-year career to the oil and gas industry and is set to become the first female CEO of a major oil company in the United States.

Hollub graduated from The University of Alabama in 1981 with a bachelor’s degree in mineral engineering, petroleum option, and joined Cities Services, which was acquired by Occidental Petroleum Corporation in 1982. Based in Houston, Occidental is an international oil and gas exploration and production company, and one of the largest U.S. oil and gas companies based on equity market capitalization.

She has held a variety of management and technical responsibilities with Occidental on three continents, including roles in Russia, Venezuela, Ecuador and the U.S. Early in her career, Hollub led geoscience and engineering teams at Occidental’s Hugoton properties, and helped develop the company’s midcontinent business unit.

As an operations manager and then as president and general manager of the company’s Permian Basin operations, she led the company’s enhanced oil recovery operations in western Texas and New Mexico. She also served as executive vice president, California Operations. In 2011, she was named vice president of Occidental and executive vice president, Oxy Oil and Gas – U.S. Operations. In 2014, she was appointed executive vice president of Occidental and President, Oxy Oil and Gas – Americas, where she oversaw operations in the U.S. and Latin America.

In May 2015, the company announced Hollub will succeed retiring CEO Stephen Chazen in 2016. In December 2015, she was named president and chief operating officer of Occidental, where she is responsible for worldwide oil and gas operations, as well as the company’s chemical and midstream operations.

The National Diversity Council selected Hollub in 2015 as one of the Top 50 Most Powerful Women in Oil and Gas, a definitive list of female executives, influencers and achievers impacting the oil and gas industry.

Hollub and her husband, Robert Glenn Vige, live in Tiki Island, Texas.
