RE:RE:FurtherSo the Berbice canyon was formed before, at least 103 million years ago, pre Coniacin, when South America was located out in the present day Atlantic rotated counter- clockwise when most of the northern part of South America was drained by the Berbice River and not the Amazon because the Amazon didn't exist back then.
Only when the South American plate run up against the Nazca plate did the South America plate tilt to change the drainage patterns to form the Amazon, with it's huge prolific oil producing areas. At the same time the Andes were formed. That's what I read anyway. So why is that relevant? Because the ancient Berbice River must have deposited trillions of tonnes of reservoir quality sediments.
Basher yesterday said that the hydrocarbons must be gas. I point the basher to Yallup and Scotchman of Halliburton, found on google, where they conclude that the heat flow is low enough and perfect for the conversion of kerogen into oil and not gas. Apparently between 80 to 120 C is required to cook kerogen into oil. Higher temperatures will convert kerogen into gas. The heat flow is too low to produce gas, they concluded. It has something to do with the thickness of the Canje source kitchen that underlies the entire Guyana Basin.
According to Yallup and Scitchman the Canje source kitchen is still producing oil to this day. It migrates up into traps. It is those traps that everybody is searching for. The ancient Berbice River created a lot of traps.
