In his new assignment, which is effective July 1, Estill will be located in Marathon's headquarters in Houston and report to David E. Roberts, Jr., Marathon's senior vice president of business development.

"Robert's depth of global operational and strategic planning experience will play an important role in our efforts to manage Marathon's continued profitable growth," said Clarence P.

In his new position, Estill will be responsible for managing all aspects of Marathon's corporate strategic planning activities, including the ongoing assessment of the company's upstream, downstream, and integrated gas asset portfolio, as well as the evaluation of new business opportunities and how they might align with, and contribute to, Marathon's profitable growth.
