Chevron Corporation, one of the world’s leading integrated energy companies with headquarters in San Ramon, Calif., U.S.A., has appointed Mark A. Nelson corporate vice president of Strategic Planning effective April 1, 2016.

“Mark is a proven leader whose breadth of international, corporate and operating experience will serve Chevron well as we actively shape the company for continued long-term success,” said John S.
