So the science is settled then? Dinosaurs and plants turned into oil? You might want to re-open that closed brain of yours and consider that Petrobas finds oil at 46000 feet how did the animals get that far under the ground? The sediments above these finds arent as old as the dinosaurs another hit to your its all dino soup theory. If dino’s turn to oil it wouldnt require sediments a probiotic process would make oil regardless.
First of all, no one said anything about dinosaurs. Oil comes from algae. Dinosaurs lived primarily on the earth. Ever see what happens to an animal such as a cow when it dies on the earth? It is consumed. If not by carrion eaters then by worms if it is buried. I think you also need to check the total depth on the Petrobras well. It is probably an extended reach directional well from an existing platform. My guess is that its true vertical depth is around 20,000’. The deepest well in the world is in the BP Tiber Field in the Gulf of Mexico. 35,056’.
