oil shale

Fuel-bearing sediment

Oil shale is sedite rock containing keite organic material called kerogen that can be processed to extract petroleum-like oil.

Unlike conventional oil deposits, the hydrocarbons in oil shale haven't naturally converted to liquid crude—they require mining and heating to release usable fuel.

The oil shale deposits in Colorado hold vast energy reserves, but extraction remains expensive and environmentally contentious.
