There is only one way to find out..

Well Admin....we know Antelope Deep is substantially lower than Antelope.  It's below the water line of Antelope.  So if it is in communication with Antelope it's not full of gas, it's full of water.  So let's not hope for the two formations to be in communication. :-)

Actually thats not true THY.
Think of slivers of rock with sealers,
Many things can be below the 1st Gas water contact. Several articles have been posted on these pages talking about just this type thing.

Yeah, it is not uncommon to have fields, where there are stacked formations, all oil bearing.   Until proven otherwise there is a possility we have stacked formations in PRL 15, each containing hydrocarbons and each formation having water below the hydrocarbons.  But, like you said, there would have to be seals between the formations.  So they wouldn't be in communication.

Think what would happen in Antelope Deep if there were no seal between AD and Antelope and the two formations were in communication.  Gas is lighter than water and floats on water.  We encountered water at the bottom of Antelope.  So gas migrating in from the kitchen down below to Antelope Deep would move on up through the water from Antelope Deep to Antelope.  It is physically impossible to have gas in AD if it is in communication with Antelope.  Success at AD depends on there being a seal between it and Antelope.  IOC appears to be very optimistic about AD, so they must believe the fault between the two formations is sealing.

What say you good friend Pet eng?

What say you good friend Pet eng?

I agree with Thy. I have been giving it a little thought and may have something to say about it tomorrow.

Good night!!

I would also have to agree with Pet and Thy, but there can be certain exceptions.
Look at Slide:14 from http://www.oilsearch.com/Media/docs/1403...faca-0.pdf
This is a cross section of the Hides field.
The Toro reservoir is what we know as the current hides gas reservoir. The proposed Koi-Lange reservoir is what we think is the Hides Deep field if it is proven to have gas. The water table is at around(or lower than) the height at each end of the Toro reservoir. The Koi-Lange reservoir comes up above the height of the water table of the Toro reservoir. If these 2 reservoirs were joined then both hides and Hides Deep would have gas in them.
Does any one know if the Antelope Deep strata projects above water table within the E/A strata?

Admin may have nailed this one we need to wait. But we have PET who knows way more than most including me so maybe he has more color to add to our speculation. Either way we wait..Only the drill bit knows.

Is Antelope Deep connected (in pressure communication) with Antelope? To determine the answer to that we must depend on information provided by IOC. I will take you through how this has developed over the years. My conclusion is NOT based on any kind of scientific information but is based on my interpretation of the information that has been released by IOC and the terminology used by them.

 Let’s start by looking at a few pictures going back as far as 2008 (IOC has taken down everything earlier than that). Even back then we were told that the structure “significantly broadens to the south” (probably should have said southeast).  See http://tinyurl.com/klb4bqv Page 18

And now another one from 2008. Have a look at http://tinyurl.com/ks6rc4r page 15. What is that big purple blob to the southeast? Looks like a big sink hole. On the other hand maybe it is across a fault and it is an adjoining fault block with another high that is lower than the Antelope structure. Is that the beginning (northwest end) of Antelope Deep?

 Now look at http://tinyurl.com/lldpu77 page 16 another one from 2008. Notice the broadening of the Antelope structure to the southeast. It is interesting to remember that the very best porosity in the Antelope wells has been at the very top of the zone where we have seen high porosity limestone and dolomite. If this is high porosity limestone and/or dolomite at the top of the zone broadening to the southeast we would not care too much if it was lower. The gas column would be thinner because it is closer to the gas/water contact but the thinner pay zone could be good porosity because it is at the top. Of course we need to remember that we are moving off the top of the reef so for than reason the porosity could be getting lower as we move away from the best part of the reef.                                                       

Another one from 2008. Look at that Mule Deer.  http://tinyurl.com/q77gxv5 page 14

See http://tinyurl.com/ntr7ff8 page 8 Note north is the bottom of the map. Also see page 22.

From 2009 see the broadening to the southeast at: http://tinyurl.com/l5zz77g page 10

Now for a more up to date picture see http://tinyurl.com/ox8hsuh page 18.  The purple, blue and red lines all appear to be faults. Note that only the most southeastern part of the map is labeled Antelope Deep. That is the part southeast of the last fault. The part north of that fault is labeled Antelope. Notice the location of the Antelope Deep portion relative to the boundary of PRL 15. There is another fault across the Antelope structure northwest of the “Antelope” Label. Keep that in mind for the next picture.

Here is a picture from the latest presentation: http://tinyurl.com/k7uzpj5 page 5. You will notice that on this picture a much larger area is labeled Antelope Deep (based on the distance from the PRL 15 boundary). Looks like they are bringing Antelope Deep up to the second fault on the previous map. This map does not show any faults but if you magnify it so you can see it well you will note that the tip of the yellow (Antelope Deep) portion overlaps the red (Antelope) portion. This means the tip of the Antelope Deep is below and under the tip of the Antelope block.

As I said, nothing scientific here. Just rolling with the punches as they change the pictures. It still looks like the Antelope Deep is a separate fault block from the Antelope block and it is lower than the Antelope block and the Antelope block gas/water contact. The only way it can be full of gas is if it is NOT in pressure communication with the Antelope block. That scenario results in the most gas but not the most money. Anyway, let’s look at the bright side, if it is successful we will have more gas.

They have obtained more seismic data recently that they have not yet shared with us. Maybe we will get another picture soon.

I hope that was not too boring!

Well we still own 27-28 percent of whats found plus a smaller bonus if you are you right PET. Bring on the drill bit.
