Vicki Hollub is an American geologist and petroleum executive who became the first woman to lead a major American oil company when she was appointed chief executive officer of Occidental Petroleum in 2016. Her tenure has spanned periods of oil-price volatility, activist investor engagement, and large-scale mergers and acquisitions. Hollub's background combines technical training in geology with decades of operational experience in upstream oil and gas and corporate leadership in Houston, Texas.

Early life and education

Born in Birmingham, Alabama, Hollub earned a Bachelor of Science in geology from the University of Alabama in Tuscaloosa, a program with ties to regional energy firms and state geoscience initiatives. During her undergraduate years she participated in field mapping and sedimentology projects that connected her to research communities associated with American Association of Petroleum Geologists, Society of Petroleum Engineers, and regional oilfield operators. Hollub's academic training emphasized stratigraphy, reservoir characterization, and petroleum systems that informed early roles in exploration and production across domestic and international basins.

Career

After graduating, Hollub joined field operations and technical teams at companies active in the Gulf of Mexico, Permian Basin, and international basins. She advanced through technical and management roles at Occidental Petroleum after joining the company in the 1980s, holding positions in exploration, production, and asset development. Her career path involved cross-functional leadership in projects linked to partners and contractors including Schlumberger, Halliburton, and national oil companies in Latin America and the Middle East. Hollub rose through operations management to executive roles overseeing integrated upstream portfolios, finance-linked project evaluation, and international joint ventures with firms such as BP, Chevron, and ExxonMobil.

Leadership at Occidental Petroleum

Hollub was appointed president of Occidental Petroleum's operations in 2015 and became chief executive officer and a director in 2016, succeeding Stephen Chazen. Her elevation made her the first woman to helm a major publicly traded American oil company, a milestone noted alongside leadership shifts at firms like BP and Shell. As CEO she oversaw Occidental’s corporate headquarters functions in Houston, Texas and directed strategy across upstream, midstream, and chemical businesses including OxyChem and Occidental's enhanced oil recovery initiatives. Hollub led corporate responses to commodity price cycles, capital allocation debates, and regulatory regimes including interactions with agencies such as the U.S. Securities and Exchange Commission and state oil and gas regulators in Texas and New Mexico.

Business strategy and controversies

Hollub pursued an acquisitive growth strategy characterized by large-scale asset purchases and an emphasis on carbon dioxide-enhanced oil recovery and unconventional resource development in the Permian Basin. The most prominent transaction under her leadership was Occidental's 2019 bid to acquire Anadarko Petroleum in a contest with Chevron. Occidental completed the acquisition with financing that included a strategic investment from Saudi Arabia's Public Investment Fund-linked entities and a large debt package, generating debate among shareholders, analysts, and activist investors such as Carl Icahn. Critics raised concerns about leverage, governance, and the terms of the deal, while supporters argued for synergies with Occidental's CO2-EOR expertise and international asset base in regions including Africa and South America.

Hollub also advanced Occidental's investment in carbon management initiatives tied to enhanced oil recovery, aligning corporate strategy with initiatives referenced at forums like the United Nations Framework Convention on Climate Change and partnerships with technology firms and academic institutions. Her tenure faced scrutiny over executive compensation, asset rationalization, and environmental, social and governance metrics that drew commentary from institutional investors including BlackRock, State Street Corporation, and Vanguard Group. Occidental's responses involved divestitures, share buybacks, debt refinancing, and a contested proxy season that tested board composition and shareholder alignment.

Awards and recognition

Hollub has received recognition from industry and business organizations for leadership in energy and corporate governance. Honors and listings have included profiles in Fortune (magazine) and Forbes, appearances at conferences hosted by CERAWeek and the World Petroleum Council, and acknowledgments from trade bodies such as the American Petroleum Institute and the International Association of Drilling Contractors. She has been cited in rankings of influential women in energy alongside leaders from TotalEnergies, Eni, and BP. Hollub's career is referenced in academic case studies on corporate strategy in the petroleum sector and in analyses by financial outlets such as The Wall Street Journal and The New York Times.
