Ed, the last report available on SONRIS Classic is dated 2/6/12 and still shows the well listed as 2H.  However it also reports that only surface and intermediate casing had been set to 7,428'.

There has been a good bit of discussion concerning the challenge of coming up with a completion design for the LSBD.  There has been much less on the challenges of drilling the well.  Other than mentions made by The Baron, I don't recall any.  When you have a dense, hard formation that has a significant tilt, it can be a substatial challenge to figure out how to get your wellbore to go where you want it.  The need to sidetrack some of the reported wells and the long drill times on some IMO are indications of the drilling challenge.  The learning curve may advance slowly if we do not get more wells soon.  It's good to see the Dan A. Hughes Plum Creek #1 preparing to spud.

The problem with the LSBD is that it becomes very sticky and hard to drill through. Maintaing an open hole is difficult.

Skip, could this be a head fake.  Have talked to several locals in morehouse and in the past several months and everyone said that this well had hit.  Maybe they didn't have good info.  I don't know but I wonder about the Dev0n call that said they had a new find and wouldn't release any info for a while until they had completed leasing.  I am talking about Crossett 31H.

james, no offense but as a professional who advises clients I never rely of locals.  I can't.  They are wrong much more than they are right.  I do not feel that Devon's "new find" has anything to do with the LSBD.  I don't think it is a head fake either.

ok, just heard that they decided to wait on the lateral until they have  a chance to evaluate the well.

Available information would indicate XTO has frac'ed and completed this well as a vertical named ExxonMobil 2 #1 Well.  Bridge plugs have probably been drilled out and the well would be ready to flow test (if not flow tested already).  They may eventually re-enter and drill out with a horizontal lateral or just elect to drill a second well.

If XTO can get significant production from this well completed as a vertical in the Brown Dense, I've got to believe this bodes well for the prospects of horizontal completions in the formation. Maybe they just found a small zone of high resistivity/ moderate permeability, but still this would indicate that such zones do exist in the BD and with the new microseismic techniques it seems they should be able to direct their laterals through such zones. I know they still have to consider other potential problems such as bringing down water from above or up from below, though.

obed, if XTO can get significant production from this well then the Brown Dense is not the tight, low permeability formation that SWN has described.  Although petrophysical characteristics will likely vary across the prospective fairway, I would be surprised if any area would support economic vertical completions.  However vertical wells can generate science helpful in an evolving exploration effort.  IMO, it would be a mistake to place too much importance on the first dozen wells.  I'm anxious to see a new round of unit applications or well permits that will get us to that second dozen.  We need more wells by experienced horizontal developers.  Now that the L SMK RA SUA; BML PROP 31-22-1H #1 is on the verge of a spud date, I'm hoping that there is a bigger player behind  the Dan Hughes Plum Creek #1.  If so then were are up to 7 LSBD wells by operators who are capable of solving the puzzle.

Just to back up what Skip is saying, the first few wells up here in the F'ville were vertical test, none of which done any good at all.  Even the first few horizontals weren't that great, but it did show it was worth doing...

Skip, keep in mind that thick, low permeability zones can be economically developed with vertical completions.  That is probably not the case for LSBD and XTO is likely just wanting to gather information before drilling a horizontal well.

Read: they may be big old Exxon, but they want to see what happens before blowing another 10 million $
