"Under Thom's able leadership, Marathon Oil's information management systems have continued to evolve in the face of an extraordinarily dynamic information technology environment that poses both substantial opportunities and challenges to our Company," said Clarence P.

"We are pleased to welcome Bruce McCullough to Marathon Oil and we look forward to benefitting from his deep technical skills and leadership experience," said Clark.  "It is essential that we have the capacity to efficiently manage the vast amount of information necessary to make the countless decisions we face each day. In addition, we must maintain a leading edge perspective on the information tools so critical to the speed and quality of our decision making. In this context, we look forward to the contributions Bruce will make as we work to profitably grow our Company in a responsible manner."

McCullough has worked in the information technology field, primarily in the oil and gas sector, since graduating from Baylor University in 1988 with a Bachelor of Arts degree in computer science.   Prior to Anadarko, he was a partner at Accenture and served in a variety of capacities for clients such as Atlantic Richfield Company, Mitchell Energy and Development Corporation and Burlington Resources.

While at Anadarko, he led efforts to develop and maintain systems and execute strategic projects in both operations and corporate support functions.  His work was particularly focused on leveraging enterprise level business systems and technologies, coupled with a substantial commitment to data analytics, to add value from improved asset performance, capital efficiency and work process efficiency.
