a dark oil consisting mainly ofhydrocarbons, crudeoil, fossiloil, petroleumoil etc.
well according to my research impermeable rock that occurs at the top of an oil reservoir is called cap rock

Shale rock / Roof rock
Porous sandstone is a good reservoir rock for its porosity enables it to store the fluid (oil?) and also to allow easy release. Compare with oil shale, where the rock is very fine grained and will not release the fluid easily. Both would ideally be capped with an impermeable cap rock to constrain the oil.

Oil shale.
Oil is commonly formed in rock or in sealed pockets under the seabed and it is from the Latin for 'rock oil' that the word 'Petroleum' is derived

Petroleum = petra, Greek = rock, and oleum, Latin = oil. So we have an oil from rock. And by common usage, all substances deriving from it.

The main one is oil shale.

sedimentary, the oil is formed within a source rock formed with high quantities of decomposed vegetation, then a reservoir rock which holds the oil and a capping rock which seals it shut in addition to this sequence of rocks, certain structures are required to stop the oil escaping, a classic would be an anticline
