Most of the intervals are well known up to the Atoka, beyond that may be explored at some time.
You would be dealing with wells in the 10-12000 ft down there and the horizontals would start to get expensive.
Pioneer are drilling verticals beyond the wolfcamp and through the strawn and on to the Atoka to add to the production. It costs another $300,000 or so to extend to each new interval but the are finding its paying off.
The 3D will give a lot more info on the Known intervals.
