Petroleum Geology Traps generally exist in predictable places – such as at the tops of anticlines, next to faults, in the updip pinchouts of sandstone beds, or beneath unconformities.

What do oil traps have in common?

❖ Several geologic structures may act as petroleum traps, but all have two basic conditions in common: 1) Porous, permeable reservoir rock that will contain quantities of oil and gas that make it worth drilling. 2) Impermeable cap rock that traps oil and gas preventing it from escaping to the surface.

How do you keep your PCV clean?

Clean it yourself by immersing it in carburetor cleaner. There should be no gummy deposits or discoloration on a clean valve. If your PCV valve must be replaced, buy a new valve, remove the old one, and insert the new one in its place.
