Nice read Spitfire - thanks. I realise you have a vast industry knowledge so I appreciate your view (or any one else who chooses to comment) on the following. I was rather surprised in the NZ drill that they failed to hit the primary target. I know you offered some possible reasons why at the time but I was assuming that drilling accuracy these days is pretty good. I am wondering how confident can we be that they will actually hit the target in the Cuba drill and what the factors are that affect this accuracy. For example, with modern day equipment can drillers be say, 50%, 75%, 95% sure of hitting the target? I realise that the nature/quality of the oil/gas/water once the target is hit is another matter, but getting to the identified target is step one and I am wondering how much of the risk is associated with just getting to that target. -any advice on this would be appreciated.
