Chevron Corporation has named Steven W. Green president of Chevron North America Exploration and Production, effective March 1, 2019.

Green, 61, succeeds Jeff Shellebarger, who is retiring from Chevron after 38 years of distinguished service. Green, who is currently president of Chevron Asia Pacific Exploration and Production, will oversee Chevron’s exploration and production activities throughout North America, including the company’s significant portfolio of assets in Canada, California, the Gulf of Mexico, Pennsylvania and the Mid-Continent region of the U.S.. Green will report to Jay Johnson, Chevron’s executive vice president, Upstream.

“Steve brings deep and proven operating experience to this role overseeing our North American upstream assets,” said Michael K. Wirth, Chevron’s chairman and chief executive officer. “He has shown exceptional leadership as he guided our Upstream operations across the Asia Pacific region over the last several years.”

Nigel Hearne, 51, will succeed Green as president of Chevron Asia Pacific Exploration and Production, effective March 1, 2019. Hearne is currently managing director of Chevron Australia and head of the Australasia Business Unit with responsibility for the company’s upstream interests and activities in Australia and New Zealand. In his new capacity, Hearne will oversee nine countries across the Asia-Pacific region. Hearne will also report to Johnson in his new role.

“Nigel brings extensive international upstream and downstream operating experience to his expanded role,” said Wirth. “His recent experience commencing operations at our two flagship natural gas projects in Western Australia makes him exceptionally qualified to assume this key leadership position.”

Commenting on Shellebarger’s retirement, Wirth said, 
“Jeff has been an outstanding leader for Chevron for nearly four decades. Most recently he’s played a central role in advancing our significant onshore and offshore operations across North America, including firmly establishing our leadership position in the Permian Basin. Beyond his leadership inside Chevron, Jeff has distinguished himself as a sought-out leader across the greater Houston community.”
