Deep Oil Below the Haynsville Shale
Y'all have probably dealt with this somewhere, but I understand that there is supposedly a huge amount of oil below the Haynsville Shale Gas find. It is real deep, but is anyone anywhere looking at trying to exploit this?

None in particular. Seems I've heard of wells being drilled to those depths though.

Not Haynesville Shale wells.
I performed a little research for a discussion in the Smackover All Over Group concerning the shale companies testing the SMK which is below the HA. The fact that some Haynesville wells were permitted to the SMK horizon led some to believe that the companies were actively testing that formation.
Out of 1388 HA wells permitted to date there have been 16 with Permitted Horizons of the Smakover. Of those 16, 3 have "plug back" notations and depths that would be obvious SMK or deeper. Encana has two, the Elmwood Land 32H in the Bracky Branch field, Red River Parish and the Burford Land LLC 8 in the Holly Field, DeSoto Parish. Samson Contour has the other being the Deltic Timber in the Sligo Field in Bossier Parish

No, I am not. The TVD appears to have penetrated some portion of the SMK as it is deeper than the actual completion depth in the HA. This is a Haynesville Shale well.

Hi Jay,
I was just looking at that pdf and the well log in there. question comes to mind, "Where can I go to learn how to read a well log?" ....Short of going to school to be a geologist...
Where do you pull those reports from? Sonris or another source?

Skip, so is it safe to say that 9-14n-14w #239980 also penetrated some portion of the SMK?

Nope, sorry if I am unclear. This research was performed using the DNR HA Well Spreadsheet because it is a comprehensive list of wells including their original Permitted Horizon. 238820 was permitted to the SMK but does not appear to have drilled that deep. 239980 doesn't list SMK so it is likely a typo on my part. I performed this research to help disprove the rumor that a number of operators were actively testing the SMK in the southern half of the Play. I believe this misunderstanding stems from the HA wells that were permitted to the SMK and the fact that there is a fair amount of discussion of a potential oil play in the SMK along the AR./LA. border. The SMK in the state line trend is sufficiently shallow to contain oil and the upper reservoirs have been long time historic oil producers. The SMK in the more southerly areas of HA development is too deep to be a reliable oil target. It defies logic that if the gas contained in the HA is dry, the deeper SMK would contain oil and liquids. If HA developers were actively testing the SMK, the well scout reports would show a TVD below the HA with a "plug back" to a shallower depth to kick off the lateral. If you check the relatively few wells permitted to the SMK you will find that such is not the case. IMO, if operators wished to "test" the SMK, they would drill completely through it. Not merely to the top of the formation. I would make sense to drill into the top of SMK to establish the bottom of the HA.

P. G.:
Keep in mind that considering the relatively small incremental cost of drilling down to the SMK once one has drilled to the base of the HA, it is really a small price to pay to take a look. In some cases, operators will plan their well locations (say, based upon seismic data) to penetrate the lower depth in a particular location for just that reason, with the idea that if economic recoverable reserves are not found, the operator has the option to plug back and begin operations to complete at the primary target zone.

Problem is that many of the larger operators are not doing so, and they are not loging the wells either. It is truly a shame that the large companies , especially Petrohawk and Chk are not loging their wells.
Of course they won't give a farmout anyways.....
