This new 12,600ft zone would appear to be in the Wilcox formation (which can be highly productive in its own right [it also covers a great deal of depth 7500ft to near 13,000ft in places] ).

I still haven't been able to identify the well they are talking about. There are a couple of candidates which are pre-1993 and as such no data is available online to view & see if either of them are the well in question.

The Wilcox (Jazz) as its referred to covers some of the production below 11,000ft. There is also the Wilcox (Triple Creek 12,900ft) which covers production at that level.

So there could be a named interval in between the above 2 that I've not come across yet or its an upper part of this Triple Creek zone.

Austin Chalk @ 14,500 - 700ft and Woodbine @ 15,000ft
