In addition to oversight responsibility for the integration, efficiency and effectiveness of its future assets, Whelchel joins Tatanka as a strategic partner in the development and execution of the company’s corporate and competitive strategy, according to a release from Tatanka.
In a statement commenting on Whelchel’s appointment, Casey said: “We are thrilled that Christine is on board. She is not only a top-notch senior midstream professional, she embodies the values and leadership qualities that we hold dear.”
Prior to Tatanka, Whelchel was with Marathon Petroleum Corp. She most recently served as senior director of crude oil gathering operations at Marathon Petroleum, where she was responsible for all aspects of the company’s crude gathering business in the San Juan and Delaware basins.
