Revised Deal

[Thylacine-2]

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!

Pet, your posts are never boring!   I would much appreciate your thoughts about the trend map on page 10 of the most recent presentation.  At first glance it appeared to me that the three trends corresponded to different periods of reefal deposition with trend 3 being the oldest and deepest.  And it looked like Antelope Deep would be part of trend 2.  Enlarging the map I see that the arrow at the end of trend 1 ends on AD.  Is it the case that if AD is part of trend1, being reef deposited at the same time as Antelope,  that AD is lower than Antelope because of downthrusting at the fault relative to Antelope?  And if AD is part of trend 2, AD could extend to the north under Antelope for a substantial distance, ,making AD even huger than huge?

Thanks so much for your posts.  They are highs on the board.

And parts of AD can communicate with Antelope is a possibility. We seem to disagree on the odds of that. The answer is drill baby drill.

This is not my field, but:

If AD is a separate formation but extends under Antelope, and you drilled Antelope 4 or some other Antelope well through Antelope and deeper into AD, would that not make AD part of Antelope, just at a deeper depth;  or would the technical definition of "in communication" in the SPA prevent that?

Thy/Getit- Regarding http://tinyurl.com/k7uzpj5 page 10, I think these trends are more related to a series of parallel northwest/southeast faults than to the age of the rocks. I think all of the trends are looking at the Miocene aged limestone. We have a very thick limestone platform across all of this area. In some places it is more than 4,000 feet thick. There are some areas where reefs have grown up on top of this limestone platform. This limestone platform and reefs have been severely faulted by the thrusting of the tectonic plates pushing together. This has resulted in the series of faults that you can see here: http://tinyurl.com/ox8hsuh page 18. You will see that the faults are colored purple, blue and red. I think trend 1 is north and east of the purple faults. Trend 2 is between the purple and blue faults. Trend 3 is the area between the blue and the red faults. So far all of the reefs are on Trend 1. We are drilling Bobcat now. Still to go is Jaguar and Antelope Deep. Looks like Mule Deer and White Tail are Trend 2. Raptor/Duckbill is trend 3. Raptor-1 to spud early April.

Since all of the blocks are the same limestone we should not think of finding a complete new section of this same formation under the antelope field. Yes, the whole area has been severely faulted and folded but not to the extent to be completely duplicated. We did drill through the Puri limestone and back into the Puri Limestone at both Puri-1 and Elk-2 but I believe we will just find this where we are drilling near a fault. These faults are not vertical so when one block slides up the angle of the fault it leaves a bit of the lower block under the edge of the upper block. But this is just around the edges of the blocks not one block under the other. This would especially be true for very large blocks like Antelope. Where it is severely faulted like Puri you might find a complete repeat section in a small block. At least that is the way I think of it.

There may be other reservoirs below the Antelope Field but I think it is more likely to be the Pale/Subu sandstones not another carbonate zone like Antelope.

I have always found this gravity map of interest http://tinyurl.com/n9fthdz page 13. What no one seems to ever talk about is the huge red trend at the bottom. Looks like it includes the west end of Triceratops, Puri and Puri Deep along with Raptor/Duckbill. But what else does it include? Maybe we will find out over the next 6 years.

Pet, I have wondered at times what ever might come of that blob also. It was presented back then as part of this amount of potential prospects when they were first really working on Tri. It's labeled as the Kerema Thrust but has never been talked about. Big mutha

[Putncalls]

And parts of AD can communicate with Antelope is a possibility. We seem to disagree on the odds of that. The answer is drill baby drill.

Could you please share your reasoning for saying "parts of AD can communicate with Antelope"?  thanks.

Doesn't IOC stil get 37% of AD plus a littler bonus  it it containdes "the goods"?

[jft310]

My drilling partner friends who made net 12.5 times theit initial investment have stated this. They think Antelope and antelope deep will communicate. They further think that over time that big formation on the slides will prove over time all these formations will connect which does not mean they all comunicate.

Further at the IOC road show it was said but they could not say that Antelope and Antelope Deep communicated but they pre drill thought they would. They have seismics that are not on the slides. This does not mean they will communicate.

I leave it to others to debate the geology. I await the drill bit and the tests and then we will know one way or the other. We get paid either way . Just more if they do communicate.

Put, if AD does not communicate, I believe the get the TCF bonus of $100 million per, but not in the higher TCF bucket.  And yes, they still own a percentage of the gas they find, but it is incrementally more of a payout if AD "communicates."  Someone throw a two way radio into that pit please.

[cybersssss]

It has been mentioned by many that if they communicate then more likely it will be water in AD. Since they found water in antelope I doubt it is oil in ad. Jft, how does your friend justify that?
