Every now and then I read something that conflicts with what I have read before - Will some one put in order from top to bottom ALL the layers of drilling and if they are oil or gas. My understanding is that the Smackover is under the Haynesville and the Bossier is above the Haynesville - is there oil potential in all layers - and what layers are above and below these 3. I know this should be common knowledge but . . . .Thanks - Any info of importance on eachlayer will be appreciated.

Shaleeeee,
If you post this question on the Main Board, you might get an answer quickly.
Also, go back through the archives one day when you have time. This has been covered before. A little time consuming but you will probably find several blogs that interest you.
Shaleeee, check the two attachments and then let me know if you have any additional questions.

Thanks Les & Ken - This shale play is kind of like playing bridge - the more you learn the harder it is to wrap your mind around the info - Les, thanks for the attachments - on the
Comstock layers it shows a depth of about 13,000 but in the Sabine Index today SWEPI licensed 4 wells for Grogan field licensed to a measured depth of 17,770 ft - SWEPI also in the Bayou San Miguel Field along with two other permits - one for Encanna and one for Comstock all licensed for a depth of 17,000-18,000 ft - so my assumption is that it will be the same shale layers just deeper for each (which is probably wrong) FYI two wells were permitted for the Zwolle Field (one for Encanna - one for Forest oil) The Converse Field - one for Chesapeake one for Forest Oil - Cypress Operating permitted for one in Pendleton-Many Field and one for Chesapeake in the Benson Field. (All March activity)
Anyway I will get on google and try to get a basic understanding - Les what did the orange starburst and the green circle indicate on the Crimson Layers?
Henry - I feel safer asking dumb questions on the local site - kinda like high school vs college. LOL
Jan if I find a site for info I will let you know. There is probably not a simple explanation,
Shaleeee, the depths you were quoting (17700 ft, 17000-18000 ft, etc) are measured depths which is the distance down the vertical, around the bend and all the way to the end of the horizontal lateral. The depths shown on the Comstock layers are the true vertical depths. If you check a Haynesville Shale well permit in Sonris, you will see the difference between the true vertical depth (TVD) and measured depth (MD).

The orange starbursts represent natural gas and the green circle represents oil. This was Crimson's way of showing the typical production for a given formation.
Les, thanks - you cleared it up for me!!!

The History of GoHaynesvilleShale.com

GoHaynesvilleShale.com (GHS) was launched in 2008 during a pivotal moment in the energy industry, when the Haynesville Shale formation—a massive natural gas reserve lying beneath parts of northwest Louisiana, east Texas, and southwest Arkansas—was beginning to attract national attention. The website was the brainchild of Keith Mauck, a landowner and entrepreneur who recognized a pressing need: landowners in the region had little access to…
