You are too funny!
Sally, I think it is just that - a rumor. Where is the discovery - Texas side or Louisiana side? There have not been a lot of wells drilled to 20,000 ft TVD in the area of the Haynesville Shale play.
The Smackover formation underlies the Haynesville and can have a 'shaley' component that is likely one of the sources of petroleum for Smackover reservoirs and possibly some of the overlying Cotton Valley et al reservoirs.
This has been known for a LONG time so is really not new. Like all of the shale reservoirs, this was considered a non-reservoir until recent advances in multi-lateral drilling, multi-stage hydraulic fracture and companion technologies came about.
At 20,000' or more, I suspect that whatever 'shale' this is, it is too deep to be economically produced even with the advances mentioned above.
What is the deepest Haynesville well? The talk i hear is much less than 20,000 feet. The "rumor" is about OIL just a couple hundred feet below the Haynesville... whatever that is and i suspect that depth is fluid. sorry for that. thanks
I don't know the depth of deepest Haynesville production...sorry.
The Smackover can be found immediately below the Haynesville in some places/basins. In some places a Buckner formation may be found directly beneath the Haynesville or equivalent. The Buckner is typically an anhydrite (i.e. calcium sulfate mineral associated with evaporitic conditions) but it is possible that, in places, it may have a shale member.
