RLCC:

Haven't heard of any leasing near there.  Partly, this is due to CHK's big pullback per low NG price.

Note:  Shell is doing an exploratory well southwest of there in 12N 8W, I think it is, into the Bossier formation.  That IP might better define the general area, although in geological shale terms, per what little I know, it is maybe 5 or so miles away.

It isn't very far, but there are several wells in that township that have marginal production for HA wells (about 3,000 mcfpd). This CHK well I was referring to has had exceptional results on almost the same choke size, and much more recently. Those wells are also west of this one, so I was just wondering if there's been any new leasing activity on the heels of this information, or any leasing activity west of that well period.

* meant to say any new leasing activity east of the CHK well on the heels of this information, or any leasing acitvity east of that well, period.

The well may only appear exceptional based on the IP.  EnCana and SWEPI drilled wells with impressive IP's just to the south and still abandoned those leases not HBP.  The decline in some of the wells were excessive even by Haynesville Shale standards and the petrophysical make up of the shale was changing.  Look at the Mondello wells in 11N - 9W as that's about the SE extent of HA development.

And the production on those Mondello wells hasn't been great.  Mondello 29, which had awesome IP numbers, has only produced 2.3 Bcf in almost 2 years.  Maybe that old Petrohawk chart that showed the 4, 6, and 8 Bcfe lines for EUR was right....

The HK EUR map has proved to be surprisingly accurate over time especially considering how early in the development of the Haynesville Shale it was made public.  Then again no other Haynesville Shale operators offered anything other than "blob" maps.

This brings to mind a question....  There is something about this area that obviously doesn't allow fracking to open up as big of an area or some such thing.  Might there be technology improvements that would allow for better EURs in the future for areas like this?

RLCC:

Oh, now I see what you're saying.  I hadn't seen that new IP on 20 13N 7W until just now.  SONRIS updated yesterday on 3-14-12, and the GUIN well finally has an IP.

 

state # 242011 -- HA RA SUG; GUIN 20-13-7 H

COMPLETED 2-22-12; GAS; HAYNESVILLE RA; 21,192 MCFD; 22/64 CHOKE; 63 BWD; 9407# CP; PERFS 13,577-17,732' MD

Yep, that's a much better choke than the sec 8 13N 7W well (which was almost wide-open or a misprint).  Looks like good pressure, too.

Interesting, to say the least.  As the locals say, a 21 million (volume) well is darn good. 

Happy for the Guins.

Can only hope that the Ashland leasing does pick back up maybe when NG prices improve (in a few years).  We'll just have to wait and see.

There is much mystery in HA wells performance. Hard to conceive how a well coming in at 21 million/day with 9400psi would not be an excellent well. For all of us, I hope it does well.

The sub-par performance of wells in the SE corner of the Play (Red River and Natchitoches) appears to be related to clay content.  In this case a lower clay content than the established  fairway.  However there are other factors in play particularly bottom hole temperatures approaching 400 degrees.  We may not know the particulars of the challenges but I think it safe to say that SWEPI and EnCana do and the result was their abandonment of considerable lease hold.

Skip I think you ment to say a higher clay content.

Nope.  EnCana provided a public statement, associated with the  announcement that they would be allowing their leasehold to expire in S. Red River and Natchitoches, indicating that between themselves and their partner (SWEPI) they had completed modeling the Haynesville Basin.  The only specific provided along with that statement was that "clay content increases as you go north and west in the basin".  This agrees with what was seen early in the Haynesville Shale drilling when wells in north Caddo Parish exhibited only a quarter to a third of production compared to the wells in S. Caddo and N. DeSoto even though the Haynesville was 300' thick with good TOC.  Over the next six months all the Haynesville operators active north of I-20 stopped leasing and drilling and moved south. 

In other words, clay content decreases as you go south and east in the Basin.
