Morphology

petroliferous = petrol (opaque) = petrol + iferous

The word has a recognizable base plus the learned suffix '-iferous', but the specialized geological meaning is not readily inferable for an average learner.

Etymology

Petroliferous comes from petrol 'oil' and the ending -ferous which means 'bearing' or 'producing', like in coniferous ('cone-bearing'). So petroliferous means 'oil-bearing' or 'containing oil'.
