Thats how I read it too.Sintez earlier had to pay 80% of the cost,that was to expensive for them so the jv agreed that they could convert the operating interest to a 10% carried interest for seismic and the next well.Its up to Energulf to negotiate other terms with a new operator.Maybe ENG is trying to achieve that the new operator pays back what they spent earlier,even what Sintez and Petrosa spent.Could be the reason why Eng`s interest isnt defined yet,19%-15%.If ENG achieves good terms for the others they could get a 19% interest?Maybe ENG also is trying to get a free carry for seismic or even the next well for itself.
