The Latest Scoop: Investigating the SCOOP/STACK Trend Using Geological, Geochemical, Economic and Financial Analysis

Abstract

Unconventional oil and gas plays continue to lead the charge in oil and gas production in North America. The SCOOP/STACK trend is part of the 32 million acre Anadarko Basin located in Texas, Oklahoma and Kansas, and has emerged as one of the premier unconventional plays in the Lower 48. Of all the Anadarko plays (Mississippi Lime, Cleveland/Marmaton, Granite Wash and SCOOP/STACK), almost all of the recent activity has been focused on the SCOOP/STACK, and it is one of the only plays in the Lower 48 to have maintained rig count throughout this recent downturn at 30-50 rigs. The STACK region in the north encompasses the Cana Woodford and Meramec plays, while the SCOOP in the south includes the Woodford and Springer plays. The focus of this study will be to provide an analysis into how the SCOOP/STACK compares to its peers in the greater Lower 48 plays in the United States. The SCOOP and STACK areas have been broken down into hydrocarbon windows based on vitrinite reflectance data, depth, test rates (boe/d) and peak oil percent. The east, west and south play areas for the SCOOP are bound by depth and commercial viability (depths relating to thermal maturation issues), while the north is limited by a thinning Woodford formation and changing mineralology. The STACK is bounded to the north and east by a change in lithology transitioning from siliciclastic-dominated to a more carbonate-rich environment, and is constrained to the west by depth and economic viability (deep, dry gas and potential over-maturity). Geological, geochemical, economic and financial analysis using wireline logs, completions and engineering data are used to discover what makes this a successful and appealing play.
