Attached are two alternate unit well applications made for the following Haynesville Units in DeSoto Parish.  You will note that in each case XTO shows two well laterals immediately adjacent to each other.  Given their proximity it would imply one will target the Haynesville Shale and the other would target the Bossier Shale.

 

S9-T10N-R12W, HA RA SUOO Unit, XTO, Pleasant Hill Field, DeSoto Parish

S34-T11N-R12W, HA RA SUL Unit, XTO, Brushy Bayou Field, DeSoto Parish

Interesting Les! Given the HA well"s vertical depths of ~12,500', what depth would you guess the proposed BO wells to be?  Also, how wide is a typical HA frac? I assume the depth and spacing is enough that the two formations will not be co-mingled. Any thoughts? 

BD, typically the targeted Bossier Shale formation (Mid-Bossier Shale) would be ~ 1000 ft above the Haynesville Shale.  This should be adequate vertical separation to insure no commingling of production between the two formations.

 

Operators design the fracture treatment for the Haynesville Shale with the intent of the fractures being contained vertically within the +/- 200 ft thickness of the formation while extending much further laterally from the wellbore. 

Thanks for the quick reply and info Les! Given those depths it should be possible to make a Cotton Valley, Mid Bossier, Haynesville sandwich in DeSoto Parish. I like those kinda sandwiches!

Tuscaloosa Trend Sits On Top Of Poorest Neighbourhood For Decades - Yet No Royalties Ever Paid To The Community -- Why??

In researching the decades-old Tuscaloosa Trend and the immense wealth it has generated for many, I find it deeply troubling that this resource-rich formation runs directly beneath one of the poorest communities in North Baton Rouge—near Southern University, Louisiana—yet neither the university ( that I am aware of)  nor local residents appear to have received any compensation for the minerals extracted from their land.

This area has suffered immense environmental degradation…
