Commenting on the announcements, Chevron Chairman and CEO Dave O’Reilly said, “As a senior officer of the Company, Pat has made significant contributions to Chevron’s success. As Executive Vice President, Downstream, she led the organization through a successful restructuring following the merger with Texaco and has put the organization and strategy in place for future success. Pat’s keen focus on safety and enthusiasm for the business will be greatly missed.”
