There were some big buyers Its more likley that they heard the well was either completed or nearing completion and tried to jump the gun
These to targets are as good a bet as one gets in the drill game. 352 #A-15 is 8 days away if sucessful the price will leap again (Jocam9 seem to believe them conected and lessens the liklyhood of success)
Then there is Vermilion to be drilled quickly after.
In the meantime Petsec is raking in plenty of cash
