In a petroleum trap,

Question

Quizplus · Accepted Answer

Petroleum traps are geological structures where hydrocarbons that have migrated from a source rock get trapped in a rock formation that is impermeable, preventing them from further migration. This can result in the accumulation of both gas and oil, contained by impermeable rocks above in the trap. Therefore, the best choice is D. Option A is incorrect because both oil and gas can be found in the same trap. Option B is incorrect because oil is not found dissolved in pore water but is rather trapped in the rock formation. Option C is incorrect because the rocks in which oil and gas are trapped are often permeable, allowing them to flow through the rock pores.
