Shale gas and oil plays have been the focus of activity in the United States for the past 15 years. Barnett Shale successes prompted extensive commercial expansion of shale oil and gas activity (Curtis 2002; Browning et al. 2013). As the testing ground for new technologies, Barnett Shale has an extensive experimental history of various drilling and hydraulic fracture methodologies that have been successfully transferred to other shale plays (Grieser et al. 2006; Samuelson et al. 2012; Browning et al. 2013). Following success of Barnett Shale, the Eagle Ford Shale emerged as an unconventional gas play in 2008 but rapidly and robustly evolved to an oil play, owing to price advantages of liquids, relative to gas.
