Plate tectonics creates areas that are ideal for oil accumulation. High productivity, especially along continental coasts, is ideal.

You can look at the oceans today and chart the areas of high productivity and compare them with areas in the past that have produced oil. Areas along continents with just the right water condition, circulation, and basin creation are shown as red in the diagrams below. Production of organic matter is key to the entire process.


Zones of high productivity are in red


Double subduction produces basins that are ideal for oil accumulation
