As I read this we have a deal for perhaps 11 wells, probably less because our leasehold acreage is not contiguous. (I'm kinda thinking out loud here, lol)
Texas permits one well per 40 acres, per horizon (read "zone") of production. with 1200' spacing to the next well producing the same horizon, and there are about 209 feet on each side of an acre. So without a map, and knowing where the other wells may be located, (bacause our docs don't contain maps and our leases are not contiguous in their totality) we cannot be too precise about the spacing requirements and the total nmber of wells we can drill. (One vertical well could obviously produce all four horizons simultaneousy, which was the original Chumley plan before it blew out.)
The spacing rules explain the Chumley production plan in part. We can drill four wells on less than 40 acres (on one acre I presume) if the wells all produce from different zones. If we intend to drill laterals, then one well per zone would be best.
The Fredricksburg Zone is the first zone encountered, a limestone formation, located between around 450 to 750 feet in this locality (always within the initial 1000 feet lithographically speaking) I think. Madeley is a Fredrickburg producer if I recall correctly. All the wells would be considered shallow, less than 3500 feet deep.
I wonder if there are any really deep wells drilled around here, the Haynesville Shale should be down there somewhere I believe. Oiljob
