some info about Welwitschia-1In the last few days I did some research about the upcoming drill of Repsol of Welwitschia-1 in the neighbouring block, left of Cooper block. Here are my results.
The beginning of the drill is scheduled for mid of April.

The drillship ROWAN RENAISSANCE can be followed [url=https://www.marinetraffic.com/en/ais/details/ships/9630066/vessel:ROWAN_RENAISSANCE?_=4a3686cdfbe057c6273cdd44340b0652]HERE (click "show on live map")[/url] it is in Mauritius already and somewhere I read it will stop again in Cape Town to load some equippment needed for the drill.
Their latest presentation has lots of information about Welwitschia-1 and the Walvis Basin.

The CPR and its update gives detailed information about the calculation of the COS, COS with AVO as well as ECOS:

They are going to drill not only one, but five targets in different depths (2 prospects and 3 leads).
Their best "pony" is the Maastrichtian prospect for which they state a GCOS of 23% without AVO and 39.5% with AVO multiplier (CPR, 2011).
A very interesting presentation (30 minutes) by Nigel Quinton, Head of Exploration of Tower, with lots of information about the upcoming drill can be find

It is quite interesting to listen and read through all this stuff, because here and there they quote and/ or link for example to HRT's results as well as the two wells drilled by Norsk Hydro in 1910 and 1911, so I think they put several sources of information together to build a integrated model about what to exspect underneath the seafloor and interestingly not only in their licence.
A few days ago on the
Hotcopper board the user Dknow posted the following transcript from a Repsol presentation given by Didier Lluch (Repsol Director of Exploration Africa). on the
EXPLORATION DAY (London– 01/29/2014):

Then we continue with Namibia, in licence 10. We are in the North there. This is the play.
That’s what we are going to drill first with the Rowan Rennaissance rig. We’re chasing Cretaceous, upper Cretaceous turbidite, source rock, the typical Turonian or up-grain source rock, and if we get some success, or encouragement at least, we’ll go down and try to test also the Albian carbonate.
What we like about this block is that it’s very different from everything else that has been drilled so far, because we have something that nobody else has; it’s four-way deep closure, very robust closure, right. So we move into this block, you know it was a continuation of what we did in Angola, and so on and so forth. So it was strategic but we chose very carefully this block for this reason.
But you shouldn’t confuse geography politics with geology, because I mean, I read a lot of papers saying that Namibia well was a disappointing result, maybe all these wells are in Namibia but for geologists they are in three different wells, right. This well is in the Namibia basin, the one we want to drill is in the Walvis basin, well yes, it is in the same setting, as this to one and this one, and it’s absolutely nothing to do. This is a different world, right. And then if you look at the good..., the elements, nobody there drilled for four way closure, no they drilled this risky stratigraphic trap, but on the other hand, these wells found exactly the source rock we’re looking for and they find them in the oil window and not in the gas window, and that’s what we predicted. And the reservoir is present all over the place all around the block.
So it seems that in our block, we have all the elements of the puzzle, no what we don’t know, if they fit well all together. What I’ve said is still a high risk, we consider as a high risk project. But it has nothing to do again with what has been done so far in Namibia. And this is a cartoon of the block, because that’s another reason why we like this, it’s because this is the Delta prospect that we’re going to drill and if it makes it, and this is huge, it’s a 1000 km2 structure, we have another three. So the upside and the fill up is in the same block, you know, we don’t have to chase other blocks.
So from my point of view there are many reasons to be optimistic about the drill of Welwitschia-1, that they will find what we are all hoping for and that they will derisk the whole Basin and prove what Marcio Mello was dreaming and talking of all the past years.
Fingers crossed
