NEW FEATURE: Texas Completions

I have finally gotten around to compiling a list of Texas Haynesville/Bossier Shale completions.  It can be found by clicking the box in the upper right hand corner like this one:


Texas and Louisiana have vastly different information resources and different ways of classifying the Haynesville Shale wells.  The list I have compiled is based on Texas production data from the various fields that host Haynesville/Bossier Shale wells.  Unfortunately, when digging deeper I find that many of the older wells on the list are classified as Cotton Valley and others are classified as Wildcat.  The problem exists to a lesser degree In Louisiana, as some early Haynesville wells were also classified as Cotton Valley and others are still called Jurassic.  Basically, I've had to go through well by well and make a judgment call.  I've got a short list of other wells that didn't make the cut in Texas that I will review again shortly, and there are some wells that did make the cut that I probably need to purge.

Because Texas doesn't use the Section/Township/Range geographical organization method, it is harder to sort the wells by geography, so I've just sorted them by total production.  Out of curiosity, the table below looks at the Texas wells by sustained flow rates (MMcf/day).  This is obviously biased towards the more recent completions, but it was interesting to see that many of the top ten daily producers are actually high on the list of total producers.  Many of the recent completions have very high initial production rates, so it will be interesting to see how the list changes over the next quarter.


The most recent wells that have been announced but are too new to have production data are at the end of the list (page 5).  I'm actively updating this part of the list (the production data won't be updated that often).  As always, this is a work in process, so let me know if you see something that is out of line.
