Question

Quizplus · Accepted Answer

Shale, salt, and fine-grained limestone are typically impermeable and can act as seal rocks, preventing the upward movement of hydrocarbons from a reservoir rock. They are not typically considered reservoir rocks themselves, as they do not have sufficient pore space to store meaningful quantities of oil or gas. Source rocks, on the other hand, are organic-rich sedimentary rocks capable of generating hydrocarbons through thermal maturation, and are not necessarily impermeable or well-suited to act as seals.
