Marathon Oil Corp. (NYSE: MRO) will add Lance W. Robertson as regional vice president - South Texas/Eagle Ford, effective Oct. 3, 2011. 

In this newly created position, Robertson will be responsible for all Marathon operations in the Eagle Ford shale play and report to David E. Roberts, Jr., Marathon Oil Corp. executive vice president and COO. 

Marathon has continued to grow its position in the Eagle Ford and expects to close the previously announced Hilcorp asset transaction on Nov. 1, 2011. Importantly, the assets being acquired from Hilcorp establish Marathon as a top-five acreage holder in the core of this important liquids-rich resource play. The company anticipates a 2011 exit rate for the Eagle Ford of approximately 13,000 net barrels of oil equivalent per day (boe/d), and expects to grow this to 100,000 net boe/d by 2016. 

Robertson most recently served as vice president of Operations - Eagle Ford Asset Team for Pioneer Natural Resources. He earned a bachelor’s degree from Texas A&M University and an MBA from Southern Methodist University's Executive MBA program. 

Since 2004 he has held a number of senior engineering and operations management roles of increasing responsibility with Pioneer Natural Resources in the US and Canada. Robertson began his career with ExxonMobil as a drilling engineer in Angola and Equatorial Guinea.
