Seitel is shooting 3-D in the SW Shelby, NW San Augustin, and East Central Nacgodoches County area and will cover depth to ~ 22,000 feet. The bottom of the shale(Bossier/Haynesville) in the Central East Nac. county is about 13,000 feet vertical depth. Below that is the Louark group that includes the CV aka Haynesville Lime,Buckner, smackover, norphlet then the Louann salt and the subsalt includes the Werner and Eagle Mills formations. Does any one know what depth the Eagles Mills is? What's at 22,000 feet. Are there any wells below the Lime and smackover with production any one know and can share that info?
Adubu, when seismic is shot it generally covers all depths. In some areas in San Augustine the Haynesville Shale is at 15000 ft and the Smackover and Norphlet would be potential deeper targets.
By the way it is just the Louann Salt rather than group.
Adubu, the only place I know of the Norphlet being productive is the Mobile Bay area in southern Alabama. There the Norphlet is at ~ 20,000 ft and produces dry, sour (contains H2S) natural gas.
