Tillman Succeeds Cazalot At Marathon Oil

Houston-based Marathon Oil marks the changing of the guard today, with Lee Tillman succeeding long-time president and CEO Clarence Cazalot.

Tillman takes over Marathon after nearly a quarter century at Exxon and Exxon Mobil. He comes to the job at a time when the oil and gas industry is facing a shortage of skilled replacements as baby boomers retire. The new Marathon chief is spending part of his first day on the job meeting with summer interns.

“Some folks that we’ve had in this summer working hard for Marathon, potential future employees, which I just think just underscores the incredible importance of people and human capital in our business today.”

Marathon split into two companies just over two years ago — spinning off its downstream operations as Marathon Petroleum and focusing exclusively on exploration and production. Tillman says Marathon Oil is just starting to reap the benefits of that split.

“Clarence and the leadership team have done a great job establishing a culture and a strategy that’s going to support that journey. And I’m, that was one of the compelling reasons that I’m here, is to be part of that journey as we really try to establish Marathon and differentiate Marathon as the premier independent E&P company.”

Former president and CEO Clarence Cazalot is remaining with the company as executive chairman for a brief transition period. He plans to retire at the end of the year.
