How can people look at this and not see this is where most of our oil comes from.
All that organic mater being forced under and being pyrolysed into oil and being
forced back to the surface. Yes they claim our oil is old as the dino's but wouldn't
it take that long to go from the ocean floor to the mantle then to the deposit and being it hasn't stopped and never will how can peek oil exist and the oil from the wells should get sweeter not thicker as they claim. Do you not see what I am seeing.

How To Display Subduction Zone Seismicityby RockWareSoftware1,037 views
Most hydrocarbon occurrences are from cretaceous source rocks. Some subduction zones (Chile, Pac.NW) have too short a history of carbon accumulation. Plus, the bulk of sediment that ends up in a wedge is likely to be scraped from subducting plate. Tectonic disruption can cause the oil to be released, creating paths for migration up and out of the sediment.
13 holes were drilled offshore WA and OR but none were deemed worthy gas producers. However, OR has methane hydrate potential.
