Can it be determined now from the large number of Haynesville wells drilled over a wide area of N LA

the extent of the BOSSIER field.  Is there now a current good map indicating productive areas and with

 a BCF estimate.           THANKS

Good question, stroud.  I think the answer is yes...........and no.  First, I have seen no Bossier map with any detail since Petrohawk's which is probably 4+ years old.  I still keep a paper copy on my desk for convienent referral.  Second, as soon as there was suficent well control (completed wells in reasonably close proximity) the major shale players stopped running logs.  Saved time and money when the race to HBP was still the primary factor driving drilling programs.  So, across a wide expanse of rock...likely no.  In some loacized areas.....yes, or maybe.  If you know how to use SONRIS go to Data Acess and make a list of wells across the area you are interested in.  Then go to Document Access and look in the well files.  If it lists a log then I would think that it would include the Bossier because all the HS operators included the Bossier in their depth definitions of the Haynesville.

With there not being a rush to HBP I wonder if the companies are now taking some time to run logs to see what they have at the different intervals?

You could check some randomly selected wells that are recent completions to see if logs were run.

Ok i figured out how to do this and have found that the bossier was identified around 10500 feet in southeast Desoto and Haynesville at 12500 feet.  I am now wondering what the difference in economics would be by drilling 2000 feet shallower as compared to Haynesville but 1,000 feet deeper than Marcellus?  I guess we will find out when EXCO starts their exploration.

A portion of the economics not related to well cost is the nature of the gas.  Wet like Marcellus. Or dry like the Bossier.  Wet gas is economic at current NG prices.  Dry gas is marginal at best.  IMO very few Bossier Shale wells will be drilled until the price is stable above $5/mcf.  Haynesville Shale wells hold the lease rights in force for the Bossier without the requirement to drill it.

Yeah there's the liquid aspect of Marcellus.  

The wildcard in the question of Bossier Shale production is EXCO.  If any company was likely to drill dry gas Bossier wells at current prices I think it would be EXCO.  All other operators will probably keep the Bossier behind the pipe for some years.

Thank you all for your reply

Excerpt from EXCO 2nd. Q report:

We are planning to drill a test well in the Bossier shale in DeSoto Parish during the fourth quarter 2014 to further assess the potential of the formation. The Bossier shale lies just above certain portions of the Haynesville shale and contains rich deposits of natural gas. We will utilize our technical expertise and recently enhanced completion methods that have proven to be successful in our Haynesville shale development. We will evaluate the results of the test and this could result in a significant number of additional drilling locations if we are able to establish attractive economics to drill in the formation.

Here is a bossier well in Sabine that's classified as haynesville, wow on the production! http://sonlite.dnr.state.la.us/sundown/cart_prod/cart_con_wellinfo2...

olddog, that's the cumulative production of 7 wells.  Look at the Well Ctn column.

oh, missed that, but still must be pretty good considering Encana decided to put 7 wells in that section?
