Abiotic Theory, Oil And Gas Deposits Sufficient To Thousands Years?
Methane clathrates are the major sources, and researchers are optimistic that the technology is safe and economical recovery can be expanded. In addition, the drilling of oil and natural gas that has been exhausted and abandoned, slowly filling again, especially gas. Land drilling and abandonment of the old should be considered as a future resource.
Most of the hydrocarbon fuel trapped in the planet Earth when it formed about 4.6 billion years ago. In Abiotic theory, almost ensure that earth have quite a lot oil and gas for thousands, even millions of years.
