can more than one gas formation [ Bossier sand,HS shale.. etc..] be drilled from the same well??

Ray,
That was not a stupid question. Stupid is NOT asking questions and just assuming, 'cause you know when you assume you make an ass of u & me!
Ray, the co-mingling of production from separate zones is possible under certain conditions. I see co-mingling requests to the LOC from time to time by particular operators. Those applications seek to co-mingle formations shallower than the Shale. I believe that the ability to co-mingle is more directly related to formation pressure than depth although the two are associated. The extremely high formation pressure of much of the HS area may present a challenge in relation to the much lower pressures of separate producing zones in the same wellbore. I would very much like to hear a response to your very good question from some of the members with expertise in that particular area.
Has there ever been good production on a Hosston Well? I haven't followed production very long but my parents and grandparents have had both CV and Hosston wells on their land. The CV's in northwestern DeSoto Parish have been really good producers for verticals but the Hosstons in the central part of the parish have been pathetic, chugging along for years producing very little. They seem to me to be a landowner's nightmare, tying down your minerals for very little income. Every once in a while they do play out though, one did in my section, otherwise I would have no mineral rights.
Can't pass it up, Jim. Why the "Tragic Peak"?
Comingling is usually done when it is not economical or practical to produce one zone, or both zones seperately. Skip is correct in that the pressures of the well bore need to be fairly close. Production rates are based on a pre-comingle test and the rates stay there through the life of the production. Usually the ownership of the two zones are the same. Although I have seen contracts negoitated between two different ventures. Again it is usually an econimic consideration.
KB,

In a new well the CV and HOSS will both have a relatively high press. I'm more familiar with the CV. It's pressure is usually depleted quickly because the operator opens the choke up to maximize the production because these formation tend to be low volumn. If you restrict the production with the choke you will maintain the pressure on the formations. So if someone was to comingle these formations they would determine what well bore pressure was going to be maintained and they would test each formation with the same back pressure. Royalties would be paid based on the pre-comingling tests. Some comingling agreements even require additional/occassional tests of the seperate zones. Now all of the above relates to wellbore comingling. You can also comingle at the surface where you only have one sales point. This is done to reduce the amount of surface equipment required. But it requires dual production tubing in the well.
There's no such thing as a stupid question. That being said-here goes a question.
Where can I find a section map of Caddo parish that would -clearly- show the sections
from 70th street south along Red River to about the Leonard road. On Sonris it does
not show this and when I called the help desk for Sonris all I got was a history lesson
but no answer as to why this doesn't show up on Sonris. I'v tried the courthouse-several
times-no help. When this is solved then my next question will be about iregular and
theoretical sections-like who decides where they are and do they change once a O/G
co. gets a permit in one?
James,
There is a law that states that the Clerk of Courts Office in each Parish have a copy of the original government survey field notes and township plats. I am sure they are in there somewhere. The township plats should answer most of your questions. There is also a state web site where this info can be accessed. I can't find the address right now. Several other people on here know it. I think you will find some land grants along the river. That is usually the case. They are generally very irregularly shaped.
And no, no sections or land grants can be changed by an oil and gas permit, or any other reason for that matter. They were established by the original government surveys (usually in the mid 1800's), for the purpose of describing and conveying what was at that time federally owned land. And in the process of the original government survey, that had to honor any preexisting land grants (such as French or Spanish) as this land had been transferred to private ownership by an owner prior to the U. S. government.

I think this link will get you what you want.
Go to the "search surveys" tab on top.
You will be prompted to put in you zip code, then you can enter you township and range.
Thank you for your reply. It was very helpful. I went to the link and found it.
Was hard to make out the sections so I will make a trip to the courthouse to see these documents up close. I guess they will let me look at them. The last
time I was there two people were not exactly sure what section I was in.
So they told me I was in both 3 and 34, and since I know where 3 starts I
know my land cannot be in both sections. I'll just go see for myself if they
will show me the survey map. What I really need to know are the sections
around me since they are not the regualr square shape by the river. Thanks
again for your help. Just one more question-what is a theoretical section?
RCd3:
Yes, you can produce gas from more than one formation in a well bore. Happens all the time. A packer is set through which tubing is run. You produce one formation through the tubing and the other up the annulus. This IS NOT commingling of production. Commingling involves the science of pressures in the different zones vs. depth of those zones.

Todd,
packing the tube up the annulus....in other words , you can get screwed without a pugh clause?
