Do they all appear in the same place in gis viewer when I look up a new application?
Also what is difference between ALternate well app and Well permit app? and how do they appear in Gis viewer?

Herman, in Sonris you can find the alternate well applications in the same area as the unit applications since it requires a hearing.

The application for permission to drill an alternate unit well(s) is a completely separate process since it requires a public hearing. Well drilling permit applications do not require a public hearing to gain approval. The alternate unit well order is probably filed in the same location as the unit orders.

It is rare that applications for units or alternate unit wells are not approved. Not because of some collusion between the DNR/LOC but owing to the fact that experienced operators know what will pass muster and how to navigate the application process.

I'm of the understanding that the gas factory is set up to reap stronger production while saving on costs. What I don't know, though, is just how they go about getting it under way. It appears they may start out drilling many wells from one pad to two different sections. I read on either this site or another that it takes roughly 1 to 1.5 years to complete the gas factory. If they are drilling 14 wells total (less the 2 already in place with one in both sections) then at roughly 3 months per well it would take 42 months so I'd have to assume they'd use more than one rig, right? Also, do they put the 1st wells in to production or do they wait for them all to be drilled 1st before putting them in to production?

Parkdota, the "Gas Factory" concept should reduce costs and time. It should also reduce environmental impact as water and condensate facilities would be centralized with water and condensate piped from the well pads to the central facilities.

I think the initial pilot just involves the pad drilling part of the concept. Individual wells only require 30-45 days for drilling so 14 wells could be drilled in +/- 1.5 years with a single rig. I am not sure if they drill all 14 then fracture stimulate or frac the 1st group of wells drilled while drilling the remaining wells.

Les, I think Encana is also planning a gas factory on section 7 of 14/14 Desoto. Sections 6 & 7 were already drilled from one location on Sec. 7

Les, I read in some testimony in a hearing to the CO state mineral board that Encana says with the FFP Rigs they can drill a well in as little as 15 days, which really surprised me. I thought maybe this was for vertical wells but the testimony said they can do those even faster. Basically they drill one, slide it over, and do it again. The rigs cost around $25k a day to rent/lease so if they were to drill 5 wells on one pad in only 75 days as opposed to 150-225 it would save them roughly $3.75 to $5.625 million. I guess it equates to a savings of roughly $750k to $1.125 million per well which could be around or above 10%. They also save on other items as you mentioned with regards to water and pipe. I read they also buy other items in bulk to save as well. I still didn't find out if they frac one at a time or all together.

Had a nice conversation with an encana rep this wekend. They claim that with the HA and the "mid bossier" they could get about to 16 wells per pad (super pad, gas factory...whatever).... I doubt that they could drill a HA horz. well in 15 days... pretty sure they couldn't.....

I did hear that they are still experminting on fracs, still not sure on the communication between wells, not sure if it will be like the Barnett....

I do know they are still avereging about 9 mill a well. Still pretty high....

Baron, I know this question is a long shot, but did the rep you spoke to mention anything about boundaries for the BO? I have their map, which is very detailed, and I am wondering if they are more inclined to drilled the BO in the stronger areas 1st as opposed to the map depicted weaker areas. Or, I'm guessing they'll hit the BO areas where they have a gas factory set up and/or infrastructure already in place.

Parkdota, I ktoo know an Encana rep and he has said for several months that the mid Bossier goes at least as far north as sections 4 and 5 of 14/14 Desoto. I was looking at your map and can't figure out what townships are northern boundaries . Remember, Petrohawk says the Bossier goes to north Desoto-south Caddo line which is a little different than Encana

Yeah, everyone's map is so different. However, Encana's appears to be much more detailed so that makes me think they've got a better grasp on where the BO boundaries actually are. Time will tell I suppose. If I had to guess the BO north boundary stops around 26-15-14 where the Encana gas factory is and then slightly runs NE, although the heart appears to be much farther south.

Parkdota, the wells in Colorado are directional wells rather than horizontal.
