The STACK refers to the stacked oil producing formations in Northern Oklahoma, but the exact definition of the play depends on which company you ask. Newfield Exploration (NFX) coined the term STACK, and announced the play to the world on its 3Q13 earnings conference call.
NFX defines the STACK as being the combination of the Meramec & Woodford shales in the northern part of the Cana-Woodford Shale fairway, covering parts of Blaine, Canadian, Custer, Dewey, Kingfisher, and Logan Counties, Oklahoma.
However, Todd Dutton, President of Longfellow Energy, remarked to NGI in March 2014 that he believes the STACK play extends farther north into Major, Garfield, Logan, and Payne Counties, and includes that portion of the Mississippian Lime as well. American Energy Partners calls its Woodford Shale/Mississippi Lime acreage in Oklahoma the “CNOW play,” while Devon Energy simply calls this area the Mississippian-Woodford trend.And more from the same link:
But that is not to say what the industry has called the Mississippian Lime, which straddles the Oklahoma/Kansas border, and the STACK formations are one in the same. According to Dutton, there are key differences between the two areas.
Both the Mississippian Lime and Woodford Shale intervals are thicker in the STACK, and the portion of the Miss Lime within the STACK tends to have a higher oil saturation, with less produced water. Moreover, the Woodford is a primary producing formation in the STACK, but is more of a secondary contributor within the Mississippian Lime.
NFX noted on its 3Q14 earnings conference call in late October 2014 that even at WTI oil prices in the low $80s, the STACK still achieves a 30%-50% rate of return on D&C costs of $10 million per well. The company had delineated roughly 2/3rds of its 165.000 net acreage position at the time it reported its 3Q14 results.
