Oil shale resources are estimated to amount to some 10 quintillion tonnes worldwide. The amount of oil they would yield exceeds the current total oil reserves by as much as 50 percent. Some 5 billion tonnes of oil shale occur in Estonia, 1.5 billion tonnes of which can be considered recoverable and are mostly enclosed by limestone deposits.

Apr 24, 2018 The most common extraction process of decomposing shale to become an oil is via pyrolysis, also known as destructive distillation, whereby the shale is heated to produce condensable shale oil vapors and non-condensible oil shale gas. This vapor and gas is then collected and cooled, which causes the oil to condense.
