RE:There was a guy speculating that a massive oil pool might beI haven't seen any more posts from Tonnacombe since the one you referred to but I think it's worthy of a repost so hear it is again ! (My favourite part in yellow)
Tidd, nobody wanted gas when shell drilled the well, gas discoveries had to be multiple TCF’s to move the dial back in the 60’s/70’s for a major, and make them consider development, when I worked in Tanzania for black marlin energy, siesmic, (We found the solo gas field down by Mtwara, amongst others)there were several plugged and abandoned gas wells drilled by agip when looking for oil, I subsequently even met the old sweat that drilled those wells working In Italy for safron energy as it was then, who mentioned he worked for agip for years, whilst I was visiting a gas well in the Po Valley Italy , and having seen agip welded on a capstan at Kilwa Masoko port I put two and two together and sure enough this guy knew the area well, and even held personal maps of the discoveries, at the time there was no infrastructure able to cope with an isolated gas discovery and the economics wouldn’t stack up for anything less than tcf discoveries, obviously that’s now changed, anyhow I’d personally be very surprised if we don’t bring in a gas discovery at chinook, given shell did, I doubt they even bothered to flow test at the time once they realised it was gas.
As for Cascadura deep, as the siesmic reflection from this zone managed to drown out the signature of the gas field above, I’d surmise that (a) the liquids in Cascadura deep which it almost definitely is to give off such a strong signal and drown out the gas field above, also extends in all directions past the extent of the gas above, otherwise a tell tale signature would have been seen on the outer perimeter beyond the highly reflective zone, given a huge gas field above, which must be charged from a working petroleum system again I’d be surprised if an oil discovery isn’t announced and alternatively the highly reflective zone turns out to be water.
Imho as long as the company makes the correct calculations from the old Trinidad datum (I believe the original siesmic was shot in this, having contacted a surveyor who worked there around this period,)to wsg84 (GPS)correctly and the drill bit is drilling where we think it is in correlation to the siesmic data, we’re all good.
Obviously all in my opinion, and having a different opinion is absolutely fine, and makes a market. GLA
