I have no idea what you mean by "40s".  These are three alternate unit well permits for Section 4 - 15N - 10W.  Nothing unusual about them.

Skip,

 

Look at the spacing between the bores.

To be more precise, 330' between botom holes on these three permits and the application for alternate wells includes 7 wells spaced at 660' ( 1 well already drilled )  and 3 additional wells in between.  The permits are for two of the original alternate wells proposed plus one newly proposed alternate in between.

Owenson, you are going to have to be more specific.  Are you looking at well permit plats?  Or an Alternate Unit Well application plat?  How about a link to the document you are referring to?

The original alternate unit well application plat shows the drilled well plus 7 alternate wells.

Can't look back to Jan-Feb to get a link to that one.

A new alternate unit plat (not on the website yet) shows 3 added alternate wells in between

the original alternate wells.  I looked at the bottom hole distance from the east line on the drilling permits.  They are 330' apart.

The question is are they drilling on 40s instead of 80s.

80 acres is the minimum spacing under state regulations.  The permit plats should be entered into the database early next week.  Let's revisit the alternate well spacing then.

I was able to scan the new one.

Hmmm.  Have you compared the TVDs for these new alternate unit wells?  I'll look at them again tomorrow when I get a chance.  It is interesting.

It looks like with these three ALT wells the production units will be 58 acres. If they drill a total of 16 wells in the 640 acre unit then the production units would be 40 acres in size.

Excerpt from Q2 QEP conference call:

 

Clearly the economics and the performance support a much higher well density, 8 wells per section, or maybe even more and we're just not sure yet on exactly how many wells that is. At some point, those wells do interfere with each other and you do see a deterioration in per well EURs. That's the reason we had not been aggressive about raising the PUD EUR even though if we look at our average PDP well, it's probably greater than 6 Bcf of EUR, the forecasted recoverable reserves to the producing wells, because of the anticipation that ultimately we're going to book this field up on increased density at 8 wells a section or more.
