A lot was bunched up around Howard-Glasscock field; but Howard-Glasscock is San Andres not Canyon. According to Laredo Cline is Pennsylvanian and Apache calls shale between Wolfcamp and Cline, Deadwood Shale. If this link works this paper is worthy of discussion; if not perhaps our moderator can get the paper to post.

I would have thought the line would be a lot farther west, I am not surprised of that result that far east.

On the "Good, Bad and Ugly" board there is a RRC report from Devon Horizontal IP 4.5 miles west of Maryneal in southwestern Nolan County, showing 22 BBL on a 1000' foot horizontal from April 2013. That appears to be about the location of red line of the Eastern Shelf in Nolan County. That suggests to me that there isn't much going to happen in the current round of activity.
