Proven gas reserves are reservoirs from which workers can easily extract natural gas. The amount of natural gas in a proven reserve is based on an assessment of the geology and current or estimated production of natural gas. Natural gas reserves are unequally distributed around the world because specific conditions for hydrocarbon formation were favorable at those locations millions of years ago. Arrange the world regions in order from most to least proven natural gas reserves.
