Chevron Corporation announced that it is making three key appointments to its executive team and realigning its existing technology and services organizations.

Effective Jan. 1, 2014, Jay Johnson becomes senior vice president, Upstream, and Joe Geagea becomes senior vice president, Technology, Projects and Services. The new roles will report to George Kirkland, vice chairman and executive vice president, Upstream. Also effective Jan. 1, 2014, Pierre Breber becomes corporate vice president and president, Chevron Gas and Midstream, reporting to John Watson, chairman of the board and chief executive officer. Following Kirkland's planned retirement in 2015, consistent with the company's mandatory retirement policy, Johnson and Geagea will report to Watson.

"These appointments ensure a smooth transition in our upstream business and simplify the delivery of technology and services to all of our businesses," Watson said. "Jay, Joe and Pierre are experienced leaders who will enhance a very effective leadership team."

Johnson, 54, currently is president of Chevron's Europe, Eurasia and Middle East Exploration and Production Company, based in London. He joined Chevron in 1981 and previously has been managing director of the Australia and Eurasia upstream business units.
