Isn't free carry MOG and CUE for drilling only? Do these free carry have 'commitments' attached normally should the drilling be successful? It would seem to me that either the two could sell thier share at any time. How can you negotiate terms prior to a success. I would have thought that MEO are the negotiaters. Why would MOG or CUE have any say. Do minority stake holders have loads of pull in this kind of arrangement? I can't see how MEO would negotiate any benifits down to the detriment of itself and other parties. I just can't get a grip on it.
