Valerie Mitchell, general manager-Midcontinent for Newfield Exploration Co., recently discussed the company's work in several Oklahoma plays including the company's target, the Springer Shale. Oklahoma's infrastructure, competitive service costs and favorable government--"in addition to having really great rock"--contribute to The Woodlands, Texas-based company's success there. The Springer, Meramec, and Woodford all appear similar and have strong commercial value, she said.
