Previously, STACK wells were conventional, vertical wells that went through different stacks of shale (pay zones). Today in the news is the STACK play in Oklahoma in the Meramec shale which stands for: Sooner Trend (oil field), Anadarko (basin), & counties, Canadian and Kingfisher.
STACK wells in north Oklahoma over their lifetime costs the same to drill regular wells but have coveted higher (initial) production numbers than regular reservoirs with less concentrated hydrocarbons or less pressure. I’ve read that STACK WELLS can have longer laterals which also make them more economical.
So STACK wells seem 2 B the frack of choice acreage in weathering the downturn in pricing in the oil & gas markets; gleefully solar prices and battery storage technologies continue to improve AND decline in costs.
Oklahoma, however, is also getting notoriety for their frackquakes so I ask….is fracking in the high pressured STACK plays causing even more earthquakes? I dunno because there are also injection wells in those two counties. http://newsok.com/earthquakes. Either way we reap what they sow.
In April of 2016, Chesapeake sold off 42,000 net acres in the Anadarko “STACK” for $470 million.
There is also in SCOOP (South central Oklahoma oil province in the Woodford shale), and SoHot (southern Oklahoma Hoxbar oil trend which is reported to have six stacked sands).
