I remember one of my sources saying Phil thought that Wahoo had one of the best chances of comercial oil finds fwiw.

Spartina- I think also Dave Holland.

Thanks Pet for that pdf by Buddin. On page 38 mention was made about"poor quality seismics data" at that time. With our updated seismics we just might get lucky ! (Improving structural interpretation) . Sure like your comments on the Talama fm. On (potential) upcoming gas kicks [to increase mud weight],maybe we can add a little lead ! (just kiddin' of course) . HAGD! ps-     Again, thanks for all you share with us.

Here is another interesting thought about finding the Talama volcanics over-pressured. I mentioned that I assumed there would be a sealing shale between the Talama and the Miocene limestone. Now let’s assume there is not a sealing shale between the two zones. That would mean that the reservoir pressure calculated in my Post 1 of this thread would be reflected all the way to the top of the Talama zone. So I had estimated the reservoir pressure at the “assumed” gas/water contact of 5,514 ft. drill depth to be 2,388 psi. I used a gas gradient of 0.04 psi/ft to estimate the pressure at the top of the limestone to be 2,290 psi at 3,053 feet drill depth.

Now if these two zones are in pressure communication the reservoir pressure of the limestone would be reflected all the way to the top of the Talama zone. If that zone is at 2,300 feet the pressure would be estimated to be 2,260 psi at 2,300 feet. Wow!!  That would be approaching the frac gradient of 1 psi/ft and would require a mud weight of 18.9 #/gal. You would need a little additional mud weight for safety so let’s say we would need about 21 #/gal. Even that mud weight would only give us a 250 psi safety factor if  the hole is kept “completely” full at all times.

A mud weight this high (21 #/gal) would exceed the commonly used frac gradient of 1 psi/ft. We normally use the mineral barite to add weight to drilling mud. We had some discussion already in this thread about the maximum mud weight that can be achieved with barite. This article http://tinyurl.com/kptksw2
Says you can get to a maximum of 21 #/gal but practically speaking this would be very hard to maintain.

I think it would be impossible drill with 21 #/gal mud without losing circulation so if this is truly the situation I think they must set casing above the Talama and plan to drill both the Talama and limestone section with the pressure managed drilling technique and no circulation to the surface.

If this is what we have we have a tiger by the tail!! It would be easy to get in trouble here.

To get the big picture here you also need to look at the seismic section shown at http://tinyurl.com/m32z6ho page 19 and magnify it to about your full screen size.

Pet, I appreciate what you share with us. It seems to excite some knowledgeable, long-timers on the board who I guess have learned a fair amount about oil and gas drilling logistics. However, to a still-layman, I have usually have no idea what your points or conclusions are when you give (and direct us to read) so much technical information. I suspect many, if not most, of the readers of this board are in the same situation I am. We don't want to look dumb or uneducated, but we have nearly no idea what you are really telling us, other than judging by the reactions of the few others who comment. So I guess you are saying very positive stuff, but could you please summarize it in a straightforward manner for the rest of us? Thanks.

Summary:
Drill please.
Only then:
Buyout please.

Movieguy- Believe me when I say that I don't think anyone on this board is 'dumb or uneducated' at all.Maybe Pet is sharing his knowledge and experience in the way he thinks best knowing there are some "petroleum enthusist" who follow his logic and thoughtful conclusions. He never advises us to buy or sell.....just to cogitate on our possibilities. His thoughts on our chances for success in our next 3 wells are a good summary for many,I think. (fwiw) HAGD.

I am in the same boat Movieguy.  Pet is a valuable resource for all on this board without question.  I have found if you ask for an explanation in laymans terms he is kind enough to "dumb it down" for those of us lacking the technical expertise of many here.   He is the smart kid in class for sure.  

Good luck longs

From where I'm standing Pet is a professional who simply enjoys exerting his craft and knowledge. Having to 'dumb it down' might risk losing some of that pleasure, as well as the nuance. We're lucky to have him here and many of his posts are gems which I thoroughly enjoy, even without understanding all of their contents in full.

Agree Admin.  It's more up to us to do a little research on the terminology he uses (copy some of his terminology into Google for instance and read about what it means) so that we elevate our understanding of the company we are invested in.  Over time you understand more and more and that's the idea; understand what you are investing in instead of asking him to spend more of his time "dumbing it down".

I agree, Admin.  Pet is in a league of his own.  I am waiting for the day someone contradicts something Pet writes (possibly on April Fool's Day?).  I would have a better chance of success critiquing a Shakespearean sonnet written in Sanskrit.
