Cheerleader, top previous Haynesville Shale well was 30.1 MMcfd.

Les, what are your thoughts about Devon flowing the Kardell Gas Unit 1H on a 37/64 choke to achieve that 30.7 million IP. Not taking any thing away from the well....it's huge....but wondering out loud what one of the Louisiana wells with an 8,000 lb. flowing pressure on a 24/64 choke would be capable of producing on an IP at that choke size. My thoughts are you'd get a lot of frac sand back, which certainly wouldn't be good.

SB, Devon is highly experienced and tends to be conservative so I assume they were comfortable with their test procedure. Some of the previous wells that tested ~ 25 MMcfd with +/- 7500 psi flowing pressure (~ 28/64" choke) may have been capable of topping 30 MMcfd.

I am just glad to see this well (and others) confirm the high rate potential extends deep into East Texas.

That's what I find to be quite interesting about this completion as well. From all that I have heard and read to date, Devon seems to be amongst the most conservative operators out there - generally not concerned with having the highest IP numbers, but rather paying more attention as to what is best for the long-term prospects of the well.

That said, it makes this 30.7mfcd IP all the more impressive and intriguing.

I also imagine that with these longer laterals (this one is said to be over 4,500'), and what is likely to be continued improvement in the fracturing technology, that we are likely to see these type of numbers happening on a much more regular basis in the future...

Does anyone have anymore information in response to remarks made several days ago regarding the shale in SA County being more brittle and having natural fracs? Apparently compared to other counties or parishes??
Does this impact the size of the well or just the drilling costs?? Neither?/Both??

Cheerleader, I know you are referring to the following statement by Southwestern Energy. It primarily results initial well rates but could also could allow for cheaper frac jobs and increase the ultimate recovery per well.

"But we think that the rock is more brittle there because of the carbonate ratio. We're seeing significantly higher carbonate there versus Northern Texas and really as you get into Louisiana it seems there is more silica sand than manganese carbonate. But it looks like that carbonate is making it brittle enough so that you can get better fractures and potentially have some natural fracturing or natural breaks in the rock. So that's always the thought right now and with little more wells we'll figure out if that's really true or not."

Hi Everyone,

An oil industry friend of my cousin's told her that the Kardell was a major discovery but that the Haynesville Shale becomes much thinner very quickly as you go south of San Augustine. She told her that Hwy 21 and around there isabout as far south as the oil companies are going to go for now. She said that all of it will be worked eventually, toward the end of the play but to the south it's thinner and a lot deeper and there's a lit of easier stuff to drill for the forseeable future. She said all the companies know that. Is this right y'all think?

This Isopach map put out by El Paso is pretty interesting:

Ahhh.... Jffree1, I have been trying to remember which Co. put out this graphic and could not remember to save my life! Which presentation was it in? Thanks!

Taylor,

The full presentation from El Paso is in the attached file. It has a few other interesting items as well, including some cross-section explinations of the various strata formations...
