Gus0,
HI100 is actually far nearer the mark than you are.
BOR needs a DW Drillship and even if Navitas get one for SL (they don't actually need one, but the current market means they may get one anyway), there is no chance of it being used in the SFB as it's going to be busy on SL for years.
So we are looking at around $50 Million just to Mob it and all the materials / consumables needed for any SFB drilling program.
Looking back at the previous campaign, we can expect a Well to take 90 days to drill and log. This time, the Wells would have to be tested and that's easily another 20 - 25 days on top.
The spread rate is going to be in the region of $1.25 Million per day, so we are already looking at around $140 Million per well, even before taking into account the consumables (Wellhead, Casing, Mud, cement etc).
He is also correct about the uncertainty in both production and injection rates - testing will be needed to be able to narrow down the potential ranges of those figures.
It is unlikely that an Appraisal Well will be used as a producer - they are drilled to delineate the field, which is often not the best place for a producer. Even so, the requirements for an appraisal well and a production well are different in terms of design lifespan and options for completion.
As for being "off the shelf tech", much of the drilling & completion equipment should be - although it certainly won't be available immediately, as the lead time is likely to be c. 18 months just for the Trees - which is why Navitas have already ordered them for SL even though the project hasn't been officially sanctioned yet.
The Production & injection manifolds certainly won't be - off the top of my head I can't think of a subsea gas/condensate development, so they'd have to be designed from scratch, as would the production and injection flowlines.
Similarly for the Floating Production system.
While there are gas/condensate fields that produce to fixed platforms, I can't think of one that produces to a floater - never mind one in the adverse weather requirements of the SFB.
The surface complexity of separating a high pressure gas/condensate stream shouldn't be underestimated, and neither should the surface requirements for injecting high pressure gas.
Then there are the offloading lines and mooring turret to the shuttle tanker which will need to be designed - again from scratch given the water depth.
So I'm willing to bet that there wouldn't be any change out of $1.25 Billion, just for the FPSO.
I doubt the original concept of just one gas injector and two producers will fly with the FIG, even if the appraisal program doesn't throw up any surprises.
They'll want to see an FDP that optimises production and recovery rates, which just three Wells is very unlikely to do.
As an LTH in BOR, I really, really hope they manage to pull something out of the bag.
But don't underestimate the significant challenges that lie ahead if they
