Funny, the timing of a sovereign management.

InterOil has resumed drilling at the Wahoo prospect in Papua New Guinea where higher-than-expected pressure and gas entering the wellbore halted a probe last summer.

The company has spudded the Wahoo-1 sidetrack exploration well on PPL 474 in Gulf Province, it said on Wednesday.

The new well is a follow-up to the problematic Wahoo-1 probe where progress was suddenly halted by a safety alert last July when InterOil unexpectedly struck gas well above its target zone.

InterOil had begun drilling at Wahoo-1, a multi-trillion-cubic-foot gas prospect, in early March last year. It ended up striking “significant concentrations” of methane, ethane, propane and butane.

“The Wahoo-1 side-track is a significant step-out from existing gas fields and will test whether the successful trends identified around PRL15 extend 170 kilometres to the south-east of Elk-Antelope,” the company said on Wednesday.

Chairman Chris Finlayson also said on Wednesday that InterOil and French supermajor Total are set to kick off front-end engineering and design work on the Elk-Antelope liquefied natural gas project, with a preferred development concept expected by mid-year.

“In 2015, we are scheduled to select a preferred development concept and begin (FEED) for the LNG plant,” Finlayson said.

“The on-going appraisal at Elk-Antelope is increasing our confidence in the resources to support a two-train project. The financing and marketing of the project will also commence this year. We anticipate first gas early in the next decade.”

Pet, could you please give us a more detailed explanation of the Wahool slide, slide 25, in the presentation? thanks!

Very much look forward to seeing a gas flare for the second time.

The wait will be well worth it and more.

Thy- I am sorry but you can probably tell about as much about this slide as I can. Previously they showed a slide at http://tinyurl.com/m32z6ho page 19 that showed a common anticline. They tell us here on page 19 which seismic line we are looking at so we can see it is running from north to south. This picture shows faults on the west side of both Wahoo and Mako. On the new picture from the ASM presentation we now have a fault (the yellow line) cutting the anticline but I can’t tell which way the seismic line is running. Anyway I assume the fault is something they did not expect and that caused the top of the formation (the aqua colored line) to be lower than expected. They seemed to have removed the yellow line that was on a previous presentation which I thought was a sandstone and the source of the gas entering the hole. They have a very light purple line on the picture but it appears to be too high to be the source of he gas which I think was near the bottom of the drilled hole.

I made some previous prognostications about how they might do this sidetrack. It would be nice to know how they are going to do this but we do not. I don’t think we can read anything into the schematic drawing where they just show a change in angle at the bottom of the hole. I think their pipe size and hole size at the bottom will not allow them to side track at the bottom. This is all a guessing game because we have not been told what size casing they have run so far.

I thought they had previously merged Mako and Wahoo into one prospect but I think they are now talking about Mako again so they may still consider it to be separate from Wahoo. It looks like Mako is higher than Wahoo and probably smaller.

Thanks, Pet! What do the two long blue lines represent?

I have no idea what the blue lines are. May be a change in formation type. It looks like the well and the top of the limestone ends at the top blue line so it may be where they think the bottom of the reservoir rock is. But really I do not know what these lines are. They do not appear to be faults.

Given we don't know how much if any of the original casing pipe in place will be used in the sidetrack well I suspect we don't have a very good guess as to how long it will be until we get to TD and well information.

Does anyone have information that can help us estimate when we might see some results of the sidetrack?
