THE JOKE has been told by generations of Jews, most famously Golda Meir, the former prime minister of Israel: ‘Why did Moses lead us to the one place in the Middle East without oil?’ But an updated version may be required if Harold Vinegar and his colleagues get their way. Dr Vinegar, the former chief scientist of Royal Dutch Shell, is at the centre of an ambitious project to turn Israel into one of the world’s leading oil producers. According to Dr Vinegar, Israel has the second-biggest oil shale deposits in the world, outside the US: “We estimate that there is the equivalent of 250 billion barrels of oil here. To put that in context, there are proven reserves of 260 billion barrels of oil in Saudi Arabia.”
