Process:  - Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms - It will turn into either petroleum or natural gas -   Perturbation hypothesis: suppose healthy kidney without problems happens, how will it affect LESS oil.  Does the supposed perturbation have an effect (direct or indirect) on the process?

no
