Hi Les,

And one "maybe near final" comment/question.  I presume that in doing all this drilling into the HS, the producers get a chance to look at BS core samples? (maybe they bother, maybe they don't?).  Should they get some additional insight into what they are dealing with in terms of BS potential?  For that matter, how much can these guys tell before they drill the lateral in the HS?  I would think there would be some indication of the porosity / mineral content / formation depth based on simply drilling the vertical?   I am guessing the info is not really enough to decide on continuiing with the lateral; otherwise there would be more "vertical-only" holes scattered around the edges...

Robert, operators do not necessarily core every well but likely would log the interval in the vertical section of the well before building the curve for the horizontal lateral.  This should give them some information regarding the Bossier Shale Formation in the Liberty Field area.

 

Because no horizontal wells in this area have specifically targeted the Bossier Shale for completion, there has not yet been a clear indicator of the commerciality in T12N-R8W.  Clearly in some areas there have been excellent wells completed in both formations therefore confirming the "double shale" development opportunity for EnCana and others in those specific areas of the play.

Fascinating reading gentleman, thank you and thanks to the Site Publisher!

Robert, it matters not what the name of the unit is, HOSS, CV, LCV, etc. (although it should).  It is the depth interval definition in the application and order that defines what formation(s) are being pooled.  As I mention in my Blog, the Commissioner put a stop to including shale intervals in with non-shale intervals in unit applications in the Summer of 2008.  Now every time I run across a horizontal "CV" well I look closely at the TVD and add it to my list if I think it is in reality a HA well.  Since the Bossier is included in all (?) the Haynesville (HA) Shale depth interval definitions, you will have to look at completion reports on SONRIS Classic to determine if production is from the HA or the BO.
