Ann: SM71 F5 Well to be Drilled (corrected), page-12

If both F4 and F5 were duds the price would collapse but they are not going to be duds .
There is some uncertainty as to the proportion of oil and gas in F4 but it is already a discovery , it has near zero chance of being a dud .
F5 should be upgraded as a prospect and the risk of operational problems lowered by the drilling of F4 .
We have not drilled it yet so as always in this business some risk still remains , but it is unlikely to be a dud .

Considering the carnage in the oil explorers at the moment BYE is holding up well .
