Much of that comes from the supergiant Samotlor field in Siberia, which TNK-BP has spent billions rehabilitating after years of mismanagement under Soviet engineers.
Both Supergiant and he had emerged from Bastion with considerably enhanced reputations, so a degree of caution with the brand would not seem inappropriate.
In 2005 he became one of the earliest western investors to take a chance on the Kurdish oilpatch, partnering with Turkish oil company Genel to develop the supergiant Taq Taq field.
When a supergiant finally goes bang it produces a massive burst of gamma rays and that burst lasts much longer because the supergiant is so big and there's much more fuel to burn through.
