Something to think about

Developing large acreage positions of unconventional and conventional oil and gas resources
I am currently working in one of the worlds biggest unconventional gas plays . One of my biggest clients spent the last year ''experimenting'' with different frac techniques on multiple wells. On each pad (lease) they drilled 2 wells. One is a vertical and one is a horizontal. The vertical is drilled and completed first to lay the ground work for the well that will pay- the horizontal. On the horizontal there are up to 10 or 15 intervals completed. Including cleanup of the well these wells can take 2 months to level out and see results that mean something. One important note...the target formation we deal with is 50-100m in depth on most wells. The Szolnok is 1200m and according to what I have read contains multiple pools/resevoirs.
Oh, and one more thing. Results have varried from watered out duds (hit a fault), to viable produceres that had water problems that we dealt with, and all the way to a 20 mmscf screamer of a well. On some of the wells that did not turn out, we came up hole and completed in another zone with success. And, these wells are all in a 30-40 mile radius.
That is my reasoning behind '' one completion on one formation on one well does not make a play.''
