Delay costs, yes, but a 25% delay due to breakdown doesn't mean a 25% blowout in costs. At least it shouldn't.
But as I said earlier, I don't see that it really matters at this stage. If the well is a success it will pay back any delays, and if it's not a success then JKA is in a lot of trouble.
In other words, exactly the same situation as it was before spud.
