Oil major Chevron has made changes to its senior team with two of its top executives assuming new roles.
The company said Michael Wirth will become executive vice president from midstream and development.
Wirth is currently executive vice president for downstream and chemicals.
Meanwhile executive vice president for gas and midstream, Pierre Breber, will take on the same role covering downstream and chemicals.
Chevron said both will continue to report to Chevron’s chief executive John Watson.
Both men will take up their new roles with effect in January next year.
Watson said: “Mike and Pierre are experienced leaders, and these moves will allow both to apply their broad experience and management skills to new areas that will generate greater enterprise value.
“Mike has systematically improved our downstream performance through portfolio optimization and efficiency.
“He will now focus on Chevron’s companywide asset portfolio and strategy while leading the company’s midstream activities.
“Pierre has broad experience in our upstream, midstream and finance organizations. In his new role he will drive additional performance improvements to build on the success of our downstream and chemicals business.”
