In a virtually uninhabitable section of South Australia, a discovery has been made which could rock the world. Some are calling it the biggest discovery of oil in 50 years. Earlier this year, a company called Linc Energy announced that tests had revealed that there was a minimum of 3.5 billion barrels of oil equivalent sitting under more than 65,000 square kilometres of land that it owns in the Arckaringa Basin. But that is the minimum number. It has been projected that there could ultimately be up to 233 billion barrels of recoverable oil in the area. If that turns out to be accurate, the oil sitting under that land is worth approximately 20 trillion dollars, and it would be roughly equivalent to the total amount of oil sitting under the sands of Saudi Arabia. In essence, it would be a massive game changer.
