This is from Bruner 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. This is a process that unfortunately takes time and unfortunately will take more time in these 6 wells because of the fact that we have these minor amounts of H2S

So it looks to me like all the puzzle pieces fit together perfectly. Exxon still has a lot to learn before they can drill a well, apply their multi-zone frac technology, and put it into production right away. They are taking their time, and are fracing one zone at a time, regardless of the expense.

As far as the frac crews hanging around between frac jobs, well that's not the case if you have several wells on the go! I wonder if they did one frac job on the Hod-1, and while that well is cleaning up, they have moved over to the Foldeak-1. Once the first frac is finished on the Foldeak-1, they move back to the Hod-1. That would be the most logical and cost effective thing to do anyway.
