Wahoo-High Impact Exploration Well

[petrengr1]

“And we're looking at high-impact exploration wells. So you're absolutely right. A discovery in this area (referring to Wahoo area) will de-risk a whole part of the geology and geography, and the prospect itself, if successful, will undoubtedly be high impact.”

So why will a Wahoo discovery be high impact?

The Wahoo and Mako prospects have merged together and I believe it will now be known as Wahoo. Wahoo is the northern of the two highs and I believe they plan to drill near the highest part of the structure. If this proves to be a reef and it contains gas in multi TCF quantities then that will be enough to be a “high impact” discovery.

But if you look at http://www.interoil.com/iocfiles/documents/investorrelations/presentationanddocuments/2012/Upstream%20Investor%20Presentation%20September%2029%202012.pdf page 17  you will see the proposed Wahoo-1 location and several other prospects in the area. A discovery at Wahoo-1 will be a very positive indication for these other prospects in this area as well as for those prospects down the coast to the southeast, up to Tuna at the Norhtwest and prospects in PPL 238 between Tuna and Elk/Antelope.

Dave Holland said: “The Wahoo and Mako prospects are an initial set of folded and faulted buildups analogous and correlative to the Antelope field.”

Page 22

I believe Wahoo-1 is more shallow than Antelope so the pressure will be less and the gas reserves per cubic foot of rock will therefore be less for equal porosity. Being more shallow, maybe we can expect higher porosity than Antelope.

For the big picture see http://www.interoil.com/iocfiles/documen...%20ASM.pdf page 22. Remember that Tuna is in both PPL 236 and PPL 238 and the well will probably be drilled in PPL 238. Dave referred to the southeastern most part of PPL 238 so there may be other prospects in this area that we have not yet been told about, unless he is just referring to Tuna.

 Dave’s comment: “A discovery here and the confirmation of a shallow marine carbonate reservoir will have a major impact on the prospectivity of both PPL 236 and the southeastern most portion of PPL 238.”

Can you see  any indications that Wahoo might have oil before drilling?. It's somewhere

Can't see anything before drilling. Might be full of water. We are in a gas prone area for these Miocene carbonate reservoirs, so I expect gas. I expect all of these prospects right along the coast to contain gas. Don't know what to think about Whale and Barracuda. These may be too far inland and the carbonate will be too shallow or outcrop. These may be prospective for oil in the sands below the carbonate if the sands are in fact present.

Dave H indicated awhile back the sandstones may be accessible from Wahoo. That's where the oil may be hiding they say in the sandstones. Csiro stated in 2003/4 that all of IOC's NG came from oil. Well where is it??Need to drill we must conclude.They are deeper we know that.

JFT- You shouldn’t use Dave Holland’s name in vain like that. While the Wahoo location is within the Pale sandstone fairway published by IOC (I can no longer find that presentation) I think the Wahoo-1 well is a high impact exploration well because it is likely to prove that the Miocene carbonate gas play extends at least this far southeast from Elk/Antelope. As I stated before this should improve the chances of finding more gas bearing reefs to the northwest and southeast of Wahoo (along the coast).

If you look carefully at the surrounding area http://www.interoil.com/iocfiles/documen...202012.pdf page 9 left ---
you will find the Black Bass-1 well that was drilled off structure southeast of Wahoo. The well did find the limestone and several sands, none of which were referred to as the Pale Sandstone. These sands had shows of gas but no mention of oil. http://www.businesswire.com/news/home/20...ion-Update

All of IOC’s work prospecting for the Pale/Subu Sandstone has been done in PPL 238. If you look at http://www.interoil.com/iocfiles/documen...nerCom.pdf page 24 (magnify as necessary) you will be able to see the Aure Scarp on the topographic map on the right side. This is where the Pale/Subu outcrops and the Subu-1 and Subu-2 core holes were drilled nearby. You can see the location of the core holes as well as the Sterling Mustang dry hole and the Moose-1 and Moose-2 wells that were drilled to look for the Pale/Subu oil. They didn’t find it at Sterling Mustang-1 (relinquished that area) and they didn’t drill deep enough at Moose (inadequate rig). At Moose they found low pressure oil in the Puri Limestone but no test. This is another place they could have used a swab unit but none was available. The best oil prospects for the Pale/Subu are probably at Moose or west of Moose below the limestone complex at and around the Elk/Antelope Field.

Phil’s dream back in 2002 was to find oil in the Pale/Subu sandstones. Since we discovered Elk/Antelope we have not heard much about the Pale/Subu. Phil did spend several million dollars trying to prove we had oil in the bottom of Antelope, but other than that, not much talk of oil exploration.

Michael Hession has a new dream or maybe three new dreams: non-operated LNG, high impact exploration and finding a strategic partner with similar aspirations. I think all of these will be directed toward finding gas and will be concentrated on the reef prospects in the area between Triceratops and Elk/Antelope. Of course a successful well at Wahoo-1 could considerably broaden our outlook to include some smaller reef prospects in PPL 236, still likely to be gas.

When they announce they are drilling below the limestone to a secondary target of the Pale/Subu sandstones we can assume they are looking for oil. That would certainly be considered “high impact exploration” if it was successful but I do not expect that any time soon.

Lets see now

-the sandstones lie below Wahoo per a map Pet has seen,that map prepared by Dave Holland

-Cisro Engineering in 2003/4 stated that all the NG IOC had found was from oil and the best place to find the oil was in the sandstones. Is it logical to conclude Dave Holland read that report ?.

-IOC has a drilling fund started in 2004 with $125 million and one of my dearly departed friends was a partner. Sal Illaqua was one of the drilling partners and he said and since verified by every other drilling partner i talk to that they receive periodic updates with slide presentations. That information on the slides is not always on the public slides. Dave Holland prepares those slides.

-The company spent millions looking for oil at Antelope to no avail

-The latest drilling fund slides show possible oil at Wahoo .Why because of my previous statements above.

-While IOC may not publicly state they are drilling at Wahoo to find those sandstones and possible oil it certainly has to be an objective of the well. To think they would drill 1/2 to possible oil would be off the mark. Since the Dave Holland provided the sandstone and it that map showed possible sandstones at Wahoo, Csiro stated the oil could be in the sandstones and the IPI slides states possible oil at Wahoo.

-It should then be obvious to all that IOC has multiple  reasons to drill at Wahoo. Will they find the sandstones and the oil?. No one knows that. Odds are Cisro Engineering knows more because they have more information as does Dave Holland than others.

A further hint IOC hopes to find 27 T's of NG when the drill bit drills the current seismics. Is that the right number well for that we also wait
