Hi - I am new to your blog and kudos on such a great site! Currently in my early learnings about the Haynesville..I have heard that it is common that Haynesville and Bossier are used interchangeably which can be a problem when reading scout tickets and figuring out which unit is the producer. I was wondering if you have any tips on determining which is which?

Thanks. The Haynesville/Bossier thing can be confusing and is different in TX and LA.

First, let's distinguish between the Haynesville Shale and the Bossier Shale (which I refer to as the Middle Bossier). The Haynesville Shale is the lower formation, while the Mid-Bossier is a few hundred feet shallower. That's the first confusion.

Second, in Texas, the Haynesville Shale is often called the Bossier Shale. It is codified this way through the field names, i.e. Carthage, North (Bossier Shale). Some other fields are called Haynesville Shale, like Waskom and Beckville. I've noticed recently that the field name Carthage (Haynesville Shale) is getting more use, so Texas may be migrating to using Haynesville to describe the lower formation.

There are only a few true Mid-Bossier Shale wells, and so far I have not noticed that they have any special classification. In LA they might be called non-unitized Haynesville strays or something like that. I guess there are no true Mid-Bossier units, so there is no firm designation.

Again, for my use, I call everything at the lower level Haynesville and make a parenthetical note for Texas wells in fields designated as Bossier Shale. Otherwise, I refer to all shallower Bossier wells as Mid-Bossier.

I hope that helped, but I fear it may have only confused you more.

Thanks for the speedy reply Robert. So just to make sure I will read the posted completions correctly, if I see a TX completion where (Bossier) is in parentheses, this is the lower Bossier = Haynesville. And whenever it is shallower than the Haynesville it will be denoted as "Mid-Bossier".

You mentioned that there are a few true Mid Bossier wells. Are those discussed somewhere on this blog? I didn't see them listed in your TX Haynesville/Bossier Shale Wells spreadsheet.

Thanks - all this is really fascinating

Correct about my classifications. In terms of completed wells, they are few. Chesapeake claims Blackstone 25 H-1 is a Mid-Bossier well, but it's officially classified as a Haynesville reservoir A well. There was a press release from EOG announcing Sustainable Forest 5 H-2 as a Mid-Bossier well, but it has not officially been reported. I noted it on my list of completions as Mid-Bossier, but technically it is a non-unitized Haynesville stray. Chesapeake is drilling another Mid-Bossier well called Muench 10 H-1, but it is technically considered lower Haynesville non-unitized.

Soooooo, as far as I can tell, there is no consistent way of identifying Mid-Bossier wells outside of anecdotal evidence from the companies. I try to keep a handle on this. You can search the Mid-Bossier link ( on the side of the page for individual wells.

Given the close proximity of Mid-Bossier and Haynesville, I'm not sure when there will be a separate classification/unit for these wells.

As more M-B wells come around I'll work out my own system for identifying them.
