Evening All,
I've said in previous posts here that I think we are getting ahead of ourselves w.r.t. Isobel.
While Navitas and RKH are currently both 100% focused on getting SL to 1st Oil (as they should be), nobody in either organisation seems that keen to get down to Isobel A.S.A.P.
This makes me think that they've seen something in the data they already have that means they don't see Isobel as a high priority.
There is another aspect w.r.t. it's distance from SL, which I'll come back to.
Concerning the cost, the 1st Rig is going to be fully occupied in drilling Phase 1 & 2 of SL for several years, so that implies they'd have to mob another Rig down there for an Exploration program.
Neither Navitas or RKH have the funds available to do that until at least SL has been onstream for at least two years, and there would be no point in farming down just to accelerate an Isobel Appraisal program - which would indeed cost in the region of $100 Million for a couple of Wells in this scenario.
There is another scenario (already put forwards by some others) that they could find a surprise when they start the development drilling on SL.
Now, there are more than enough holes already poked into SL that I doubt it will be a Geological surprise.
However. the one previous attempt to drill a deviated Well in the area was a complete failure and they have never gone horizontal in the Reservoirs either.
So if there are any issues, it could be on the mechanics of drilling the tangent section to get to the Reservoir and/or the horizontal section within the Reservoir itself.
If Navitas / RKH are prudent (and so far they seem to be), then they really should have an Exploration / Appraisal Well or two in their back up planning.
So if they do have issues on SL, then they have the option to go to another location at short notice while they analyse the problem on SL and work out how to solve it.
However, in this scenario, I don't think they'd go as far South as Isobel.
I think they'd go for a much closer option, which then has the potential to be tied back into the subsea production manifolds that they will put in place for Phase 1 & 2 of SL.
Isobel is simply too far (over 20km, if I recall correctly) from SL to be tied back like this - even if the crude wasn't waxy, which we know it is.
So Isobel would need a completely new Development (FPSO, subsea trees, flowlines, manifolds etc) to bring it onstream.
In this scenario, I suspect the operating rate will be around $1 Million pd, so including moving, drilling, E-logging and moving back, I'd be looking at around $35 Million for the Well.
This would NOT include testing, as there would be insufficient time to mobilise once from elsewhere and the cost wouldn't justify having one in the FI on standby.
