LB:

I wonder how far due east this quite superior shale actually extends? That's one sweet super well.

And from what little I know about this particular RR location, I can only assume that there's no drastic dip in the Martin Field BO/HA like there is in the Ashland Field (in Natch. P.), is there?

GD, actually Sections 17 & 18 in T13N-R8W do have a strong dip from north to south.

Interestingly Section 29 appears to have a strong dip but in the opposite direction - south to north. This information along with the limited Ashland Field information seems to show some type of high or ridge extending east-northeast from the Wiley Hunter 29 surface location.

Hi Les and GD-

For us novice folks, could you all explain the dip (dips?) you are referring to and how it relates to drilling?

many thanks,

R B

RB, dip just refers to the angle of the formation as you move horizontally (ie west to east) and indicates if the formation is shallower or deeper in a particular direction. For example the Haynesville Shale looks to be over 400 ft deeper at the end of Wiley Hunter 29 horizontal lateral than at the beginning of the lateral. Because the lateral was drilled from south to north, the formation appears to slope down to the north. In most areas the Haynesville Shale is almost flat or slopes to the south.

In regard to drilling, the operator has to be aware of the formation dip so he can "steer" the horizontal lateral in a way to keep it in the correct position in the formation. So the lateral may need to be "steered" up or down. Operators are no only targetting the Haynesville Shale but are actually attempting to place the lateral in a particular layer of the Haynesville Shale. Think - trying to hit the 8th floor of a series of 15 story buildings stretching for one mile up a hill side that slopes at 3 degrees. Oh - and two miles underground.

Also, initial information indicates the Haynesville Shale may be 2000 ft shallower in the Ashland Field than in the Martin Field but this is very preliminary.

Whoa.  A drastic down dip and an up dip that's within miles of each other, i.e., in a somewhat counterbalancing ridge (?) (if my geologically-challenged understanding is interpreting this correctly).

 

I find that sorta amazing.

 

And it seems to me that someone should animate a visual presentation of this eye-popping strangeness and/or at least offer a Jurassic (?) explanation (possibly an academic paper) as to what actually happened all those many million years ago to cause such a dichotomy of strata/formations.

 

Now, conversely, if this type of shale geology is a bit more normal than my rather limited comprehension assumes that it is, please ignore my perplexity, LB.

GD, it would be great if we could see the EnCana and Chesapeake geologic maps for the Martin-Liberty-Ashland Field area.  Maybe a little espionage is required. :-)

 

I am equally perplexed by the apparent "updip" location of the Ashland Field versus the Martin Field.

I'm with ya, LB.

 

Maybe some goodhearted soul will cough it up when they feel the urge.

 

And in time, the unvarnished truth usually does rises to the top of the rue, like cream.

I think the latest "super" well here is actually south of "the Martin Crossroads" (or 90% at least), if this means where the roads cross in Martin.  And if you look at all the IP's, initial CP's, water production, and actual gas production, I am not seeing an absolutely consistent trend, though three really low IP wells are to the south, though also mostly to the west; one thing I have noted is a number of wells to the NW of this location with actual production data tending to taper off pretty fast.  At any rate, I guess I am just saying that to my amateur's eye, the consistency in the area is low, which could reflect the inconsistent geology.  I'd love it if we had the results of the espionage, but I strongly suspect everything gets tightly held until leasing within 10 miles is a complete nonissue...

Robert, you notice that I said "as you move south from the Martin crossroads" which is not the same as a definitive statement everything "south of" some reference point.  I used the Martin crossroads as a reference rather than a S-T-R because that is somewhat of a local landmark.

 

The comparison of the results from Sections 29, 32 & 5 are very telling but Sections 31 & 4 will provide additional data points.

I have to agree we need more data.  I did a bunch of sonris trolling yesterday evening that left me feeling like there was still hope for this area being productive at moderate gas prices, but in 3 months, we should really start being able to see things I would think.  There was another well or two that came in at reasonable IP in the vicinity, and it looks like wells coming in at 10-15 MMcf/d is more the norm these days, due to choking no doubt.  I have become a great doubter of the absolute value of IP, mostly through looking at second month production data on wells across the play, but I have yet to get really systematic about any analysis.  Somebody also had a pretty good CP vs. production analysis, and while it correlates, it is not absolute.  "Too many variables" is an understatement.  The wells that worry me are the ones that mysteriously drop to either nothing or next to nothing in short order, and those exist both N and S of a line through Martin.  I guess I would also say I am happy we have not yet gotten another 3-4 MMcf/d well in my area of interest (my apologies to anybody in those well units; I hope the drillers can figure out how to remedy the situation).  So anyway, I recognize my hopes for this area have a pretty strong subjective edge to them; just hoping that there is actually a lot of GIP, that they can hit the right layers and refine frac conditions, and that there actually is another productive layer (BS) to go after.  Thanks for your insight and patience; I should be wasting time on other things, but understanding this stuff is an interesting challenge.

I wonder if the 241167 well using the same pad will be that good. Sure hope so. Les, do you happen to know how long before division orders are sent from the time the well has gone to sales?

PS, I will be on the lookout for the test results from the Wiley Hunter 32 well.

I am not sure how long the time from the initial production date. The well was placed on production before 10/25.
