Oil Shale

Oil shale is different than shale oil. Shale oil (and gas) occurs in rocks where the oil is as a liquid between sediment grains. On the other hand, oil shale does not contain liquid petroleum and is actually the rock marlstone which contains kerogen, a precursor to oil. The kerogen must be heated to more than 750 degrees to convert it into a ...
