Question

Quizplus · Accepted Answer

Unfractured shale, salt, and fine-grained limestone are impermeable and therefore good candidates for seal rocks, which prevent hydrocarbons from escaping out of a reservoir. They are not good candidates for reservoir rocks, as they are not porous and permeable enough to hold significant amounts of oil and gas. They may or may not be source rocks, depending on their organic content and thermal history.
