SCOOP and STACK Oil & Gas Production
SCOOP (the South Central Oklahoma Oil Province) and STACK (the Sooner Trend Anadarko Basin Canadian and Kingfisher) are the two main horizontal-drilling plays in Oklahoma's part of the Anadarko Basin. Both target the Woodford and other formations and produce oil, natural gas and natural gas liquids together.

Oklahoma's Shale Plays
Why they matter
- SCOOP and STACK made Oklahoma a major shale state after about 2013, adding horizontal oil and wet-gas production to a basin that had produced for a century.
- They sit near Cushing, Oklahoma, the delivery point for WTI futures (Cushing), so their barrels have short, cheap routes to the benchmark.
- Wet gas and natural gas liquids make up a large share of the output, so returns depend on NGL prices as well as oil.
Known issues
- Disposal of produced water has been linked to induced earthquakes in Oklahoma; regulators have required reduced injection volumes in affected areas (see how fracking works for the seismicity data).
- Well results varied by county, and several operators have shifted capital toward the Permian, so rig counts here are modest next to the Permian's.
- Active rigs are on the weekly market pulse.

SCOOP and STACK FAQ
How many rigs are drilling in the SCOOP and STACK?
Baker Hughes counted 39 active rigs in SCOOP and STACK (Cana Woodford + Granite Wash) in the week of Oct 9, −1 week on week and 6% of the 603 active US rigs.
Who are the biggest operators in the SCOOP and STACK?
Companies in this site's directory with material producing positions in the SCOOP and STACK include Devon Energy, Continental Resources (some hold non-operated interests). Ownership and the other basins each one works are in the producer table above and in the oil company directory.
What is the difference between SCOOP and STACK?
They are neighbouring parts of Oklahoma's Anadarko Basin. SCOOP lies in the south-central part and targets mainly the Woodford and Springer formations; STACK lies to the north-west, around Canadian and Kingfisher counties, and targets the Meramec, Osage and Woodford. Both produce a mix of oil, gas and natural gas liquids.
Are SCOOP and STACK the same as the Anadarko Basin?
They are the best-known horizontal plays within it. The Anadarko Basin is the larger geological basin, running across western Oklahoma and the Texas Panhandle; the Anadarko Basin page covers the whole basin and its EIA output figures.
