Sorry ssc,
On the conundrum, I did misunderstand, but I'll stick to my version of huge/large gas finds (although I have not said there were no liquid showings).
On the question of gas/oil volume conversion, without being pedantic, the general rule is 1Tcf of gas = almost 170 million barrels of oil equivalence (boe) [ITcf=170mmboe].
Accordingly, if you look up the respective NSAI estimates per Blks 2,3 and 4 wells you will see the equivalence. For example, - and from memory - in Block 2/Bomu, NSAI estimated the possible existence of 230mmbls. Somewhere around 1.35Tcf of gas.
cheers,
