>Am I correct in thinking that what Exxon is doing in the Piceance Basin would be very close to what we may expect from them when they start testing the Sloznok?? This process they are using doesn't sound like horizontal drilling per se but rather multiple fracturing at many points all the way up more of a vertical well bore?

Multi-zone fracing can be used in both horizontal or vertical wells. Almost all of the drilling in the Piceance is vertical if I'm not mistaken, and up to now, all the wells in the Mako Trough are also vertical.

MZST will probably be used in the Mako Trough as well, but perhaps not on the Hod-1. I would imagine they will want to move slowly and frac one zone at a time and study the results before moving on to the next zone. Lyle Nelson of Falcon talked about this back in 2007.

"Now once the testing stage is finished in these different wells, and we understand what each individual zone will contribute, we are able at that point to do multiple frac jobs and stages, for example like they do up at Pinedale, all at one time and not test each individual sequence. So that is going to be real big advantage in the future when we go into the exploitation phase. But right now we need to know what we have got. All of our strategic partners are going to want to have the same type of testing program that I have just described to you so they understand whenever we ramp up the operation to go into the exploitation phase what size drilling rigs we are going to need, what depths we are going to be drilling to and what we are going to be completing in."

And here's a quote from Anders Heri, head of reservoir management for MOL (April 2008)

" What technology we'd like to use really depends on the future production potential. We would like to use ExxonMobil's multiple zone stimulation technology or something similar to that, where we can really perforate and set in production more than 100 meters or several hundred meters of reservoir zones."
