No, not gobbledygook. His assessment of that production basin is correct but please note that “Crusty” indicates “migrated” to the basin; to which I agree.
The question is, from whence is the source of the petro-hydrocarbons to migrate? Does Crusty believe that it is the decay of carbon-based life-forms? We’ll allow him to answer.
If so, would not the known average percentage of decay of carbon-based life forms need to be evaluated?
The death of a carbon-based human life form weighing 200 pounds results in -at best- 2 pounds of carbon-based material (note, the human body is approximately 90% water and bones are calcium).
Those assumed 2 pounds, when undergoing the pressure and temperature conversion to petro-hydrocarbon (assuming an ideal of 100% conversion) would likely provide under 0.1 pounds of recoverable oil (best scientific estimate).
A single gallon of WTI crude weighs around 7.2 pounds, possibly representing the decay of 72 humans.
When extrapolated to the assumed history of life on Earth, we must ask, is this sensible to assume “decay” as the genesis/single source of O&G production as we know it today? I leave the answer to you.
