Thanks for the article and interesting video link to Exxon's work in the tight sands of the Piceance Basin. The following sounds very familiar to the drawings/charts of the sloznok you posted to the board many months ago, when there was considerable discussion about whether horizontal drilling and then fraccing was going to be workable in the Mako:

"The relatively thin sand layers containing the tight-gas reserves are up to 16,000 ft below the surface and tend to be isolated; however, many of these zones may be within 20 ft of one another. Optimizing production means that as many as 50 of these gas-rich zones may have to be fractured."

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?

Regards Paul
