With a project of this quality I'd hope they'd be able to get a 70:30 debt equity deal. So the total equity component may be as little as ~$120M.

100kbbls seems pretty high, they are obviously not planning on a long plateau. Keep the pressure up with gas reinjection and just pull it all out in 4-5 years, then keep going with the tail until it's uneconomic, probably just a few years more.

Re costs, a new build FPSO would be the best part of a billion, surely? It's not just a simple separator with a flare, it's going to have to be built for gas reinjection and condensate stripping. Thinking the well cost will probably be more like $60-80M fully tied in as the water depth is shallow and they would be drilled as a big campaign which saves mobilisation.

Anyway, there is enough info in there to build a simple DCF model and come up with an estimate of NPV net to CVN. Just spitballing it I think it should come out at least 20c a share just for this oil stage. Pavo and Apus to be drilled in the next two years too, which will be exciting.
