The pay zone on the first CHK well on the property is 195 feet.
For the Haynesville shale only, give or take a few feet.

Is it that they didn't have the means of drilling in the haynesville or that NG prices weren't high enough to justify the expense of exploration or drilling, or is it a combination of both?
Posted on 6/19/08 at 9:16 am to TigerDog83
Does that mean that the pay zone could be bigger?

Nobody even thought about producing shale gas with a couple of exceptions until the Barnett shale in Fort Worth was figured out by Mitchell Energy in conjunction with a rise in gas prices. The advent of slickwater "Fracs" and the technological advances in horizontal drilling have been the main drivers along with gas prices in shale drilling. The Haynesville shale was an unknown prior to the early 2000's, save for maybe a handful of wells that penetrated it in the last few decades. Chesapeake is probably the best shale gas driller in the world, and they have benefited from their mistakes in the Austin Chalk in the late 1990's. Although that formation almost broke them, it taught them how to drill and complete wells in challenging formations horizontally. Combine this knowledge with the new frac technology and higher gas prices and the Haynesville shale is a feasible exploration target.

It is going to vary between wells, even close distances such as the Chesapeake wells. 200 feet seems to be an average value in lots of the wells in LA right now (per HK), but every company will somewhat skew these results.

Thanks for the info, yea I remember reading how CHK had a really tough time at one point.
Posted on 6/19/08 at 9:25 am to ShreveportTIGER318
Is it possible for them to pursue both the cotton valley and the haynesville at close distances or even using the same wells?
Posted on 6/19/08 at 9:28 am to ShreveportTIGER318
Probably can't commingle these zones due to pressure differences right now. They will be able to develop the Cotton Valley from the same well pads using different well bores if the Cotton Valley is worth pursuing though.

Any idea what it might look like yet in T19 14W Sec 23 or near? Drilling cotton valleys but have not heard of Haynesville yet

Samson drilled a well to the shale (Muslow well 12-19N-15W), and they are currently fracing it. It is a vertical well. Nadel and Gussman appears to be drilling at least one of two wells they have permitted to the shale as well, again vertically. The shale is likely to produce here, but it definitely thins as you move northward here. Best bets are to watch the Samson well and see what it does. They found that nice Cotton Valley sand in their Light well, and Nadel and Gussman had the same sand in one of their Franks wells, but it appears to be rather lenticular because it wasn't in the Muslow well 3/4 miles to the north of the Light well.

I was told by one of the hands on the Franks 22, that is probably being fraced any day, that they were going to go horizontal but changed their way of thinking, but they could come back and go horizontal later if warranted. Any truth to this?
Posted on 6/19/08 at 10:42 am to oldawg44
Yeah, it's not that difficult to drill a horizontal from a vertical well bore as long as the casing is of a large enough size (5-1/2" or bigger).
Posted on 6/19/08 at 11:35 am to TigerDog83
Do you know if any of the companies are looking at the 12 12 6 areas at all? How far deep are they willing to drill in order to get production.
thanks everyone
Posted on 6/19/08 at 11:36 am to ShreveportTIGER318
Is that well in 16n 16w 23? They are going to drill another well in the same section already?

Again if you already know that it is part of the Haynesville Shale and learned that forty years ago then why go there again. Obviously, it is there then why do it again.
I am no expert but do work in the drilling industry. Seismic work and other logging tech have improved 10fold in the past 40 years. Some companies don't have access to other companies logs/well data. Have thumper trucks(what we call them) been in the area? Schlumberger will log a well, have 4-5 trucks several miles away from well. These trucks put down pads that send vibration/sound down and are picked up by logging tools/logging truck at the wellsite. Tells them depths of formations, if there are fault lines, etc. This data give operators(Petrohawk) information about types of formations, and helps them pick spot for other wells. Hope this helps.

Thanks Justbill for the info.
Another question: CHK has offered me $25.00 per acre to do sizmick (spelling ?) across my land and pay me some day in the furure. Should I sign up?

16N 15W, I may have messed up the one I am talking about is in section 14, my bad. but this well is about to be fraced and they are drilling another well very close to it on the same tract of land

BP has been drilling in the New Roads/Morganza area for years. Producing wells in the tucsaloosa sands as deep as 22000'. They have drilled deeper wells. These wells are expensive to drill, 20 million plus. They are also HTHP wells, high temp high pressure. Most of the wells are vertical.
I hear the BHT (bottom hole temps) in the HS are up to 350 deg. I don't think they are considered high pressure wells.
I have heard about ENCORE Aquisition drilling wells in Southwest Miss and the Florida Parishes in La, in what is being call the Tuscaloosa Marine Shale. Producing oil and some gas. Horizontal drilling. Here is a link that has some good reading.

just some information for you. Seismic Exchange asked to contract with me on my property in Goldonna, LA back in Dec of 07. They paid us 25$ per acre to do the testing. As of today they have not done any testing on my property but just yesterday they told me they would be on the property any day to do it. This is 3D Seismic testing. Does anyone know anything about Seismic Exhange or have heard who they may work for?
Thanks so much

Thank you for the information. I've read on the forum that my land located at 12 12 6 in Natchitoches Parish might be too deep to drill in. I know 40 years ago they did a 2D seismic of the property and found gas/oil however it was too expensive to go after and didn't have the technology they do know.
