Chevron Corp. (NYSE: CVX) made several leadership changes on Dec. 10 including naming Dale Walsh as Chevron’s next vice president of corporate affairs to help navigate what CEO Michael K. Wirth called the “ever-changing geopolitical and social landscape.”

Walsh, currently Chevron’s president of Americas products who will begin reporting to Wirth effective March 1, will succeed Joe Naylor when he retires after 36 years at the San Ramon, Calif.-based oil and gas company.

In a separate appointment, Chevron also named Navin Mahajan as the company’s next vice president and treasurer. He will succeed Randy Richards, who is retiring after 40 years with the company including helping Chevron pay down debt over the last few years, Wirth said.

Mahajan currently serves as vice president of finance downstream and chemicals. Following his appointment, which will take effect Feb. 1, he will report to Chevron’s vice president and CFO, Patricia Yarrington.

Wirth said Mahajan has broad experience and financial acumen that will help guide Chevron’s financing and cash management strategies at a time of “growing production and cash generation.”
