New Feature: Mid-Bossier Wells

Since the Mid-Bossier Shale has become a more defined entity and more producers are targeting it, I’ve decided to add a tally of Mid-Bossier wells to the site. The list is a work in process because neither Texas nor Louisiana have a strict definition of the formation, and no wells carry a “Mid-Bossier” designation. Most wells that I’ve included come from producer presentations and hearsay. The data is backed up to the extent possible with information from official sources and newspaper reports.

What is known is that the Mid-Bossier Shale is a dark organic shale with some similar geologic features to the Haynesville Shale. It is located between 200 and 400 feet above the Haynesville Shale and is most prevalent in the southern part of the play. That’s not to say the Mid-Bossier doesn’t extend to the north somewhat. Each producer that is looking at the Mid-Bossier formation has a different definition of the play’s boundaries. Until more drilling is done, the northern boundary line will stay in flux. Personally, I think the formation might run farther north than most maps indicate, but the northern part of the formation might have unfavorable geologic characteristics (i.e. too high clay content) to make it a desirable target.

I will update the spreadsheet with new information as it becomes available. As with all of the other data I publish, I put this out there as a public resource that remains a work in process. I do not hold out this list as The Definitive List. I’m sure there are omissions. If you see any, please let me know by email (haynesvilleplay (at) gmail.com).

Thanks for making this a separate list. Really enjoy your site - definitely stands out as being one of the most thorough, objective, and detailed oriented sites. Keep up the great work!
