One can get the estimate from production levels of near by finds of the block also calculating and comparing Cairn india and selan exploration output.
I understand the oil reserves are huge. Brazilian Govt has stopped private particupation in oil exploration in that region post this find. Now since the find has been successful. these participating coys can sell there stake at huge premium.
