i am wondering if anyone has any opinions on when infill drilling may begin to occur. i did search the website for similar topic and found an interesting discussion on well spacing that touched on fill drilling but was geared more toward spacing. i realize economics have a great deal to do with it, but, what other factors determine a companies infill program.

Here are examples of Infill wells begin drilled.:

Go into SONRIS Lite, click "Wells By Fields By Organization", put in "Field number-8871" (this is Ten Mile Bayou)-Operator E111. (This is EOG.) The Ten Mille Bayou Field is east of the Trenton Field

Keep in mind- numbers are only from SONRIS-which often is months behind in reporting.

You find 21 permits in a total of only 4 sectioms.

Wells in section "Sustainable Forest 5" is 7

Wells in section "Blackstone 4" is 5

Wells in section "Red River 4" is 6

Wells in section "Red River 5" is 3

I will give one example from these wells.

Sustainable Forest 5 Below

001-came in at 12.638 mcfd

002-came in at 10.262 mcfd

003-drilled to depth-set casing-not fracked

004-drilled to depth-set casing-not fracked

005-completion ops

006-completion ops

007-drilled to depth, set casing-not fracked.:

Hopefully when they finish "playing" in the Ten Mile Bayou Field, they will come over and "play" in the Trenton Field, where they have 12 sections.

I am in one of these sections with a producing HS well. Around January they built another pad and were to start an altenate well. Permit has since expired due to the 180-day rule.This never happened, due I was told by not getting the number of rigs they had expected. Other factors may be involved.
The number and timing of alternate unit well drilling will certainly be impacted by economic considerations but it is becoming clear that some operators are experimenting with completion designs involving multiple wells in an effort to improve EUR.
Skip,

I believe another of the deciding factors on development of any given section would be the presence of already installed (or easy to instal) pipelines with take away capacity.
The alternate unit wells will not be drilled until sometime after the unit well. The pipeline serving that unit well will have been designed for the capacity required by an operator's development plan for that unit, ie. all the additional wells to come.
PL, I get nine wells permitted in S4, 11N, 12W, Ten Mile Bayou for EOG, as follows:

#240,361-HS
#240,494-HS
#240,960-BS
#240,981-HS
#240,486-HS

All of the above are surfaced and landed in S4. Another permit, 240,539, expired.

The following EOG wells are surfaced in S9, 11N, 12W, but have a PBHL of S4:

#241,073-BS
#241,084-BS
#241,085-BS
#241,224-BS

This makes a total of 9 wells (four Haynesville Shale and 5 Bossier Shale) that are to be landed in S4. I don't get 11 as indicated above in your post. Have I missed something? Correct me if I am wrong.

Thanks.
I just went off the SONRIS outline page for field and operator. I did not investigate each and every well-there could easily be expired permits in the group
241223 loc in sec 9 pbh1n sec4
241486 permitted 6-8-10 in sec 4
You are correct!

When I go to Sonris wells by S,T &R by parish, it doesn't list #241,223, but when I put that serial number into wells by serial number, it comes up as the 4th Alt. well in S9. It is a HS, so that is 5 HS and 5 BS PBHL in S4, with 5 surfaced in S4 and 5 surfaced in S9.

There are 5 HS and 5 BS.

Thanks very much. Sonris can be VERY strange!
KJ, timing will be a function of the following factors:

1) Operator development philosophy - Drill out entire section -vs- add 2-4 additional wells to each section
2) Amount of acreage held by production
3) Haynesville Shale rank in operator's inventory
4) Operator earnings growth target
5) Section access to gas gathering and treating capacity
6) Natural gas supply - demand balance
I think the biggest factor will be #3. Some operators have bought leases all over the country in emerging shale plays. As soon as these operators get their Haynesville leases held by production, I'll predict they move out to hold leases in those areas, and we won't see them back for a while.
It seems to me that if the "Gas Factory" model is in play, then the infill will occur at some later date when the operator can contract a gas sale. The number of wells currently being drilled is to hold acreage and not necessarily to reach max production. Once the cheap acres are held by production, then a prudent operator will turn on the factory when "purchase orders" are received. Thats how I see the infill wells in the Shale.
