For the majority of uses the two energy sources are interchangeable except for small power plants and besides fracking also produces oil in large quantities. Although the largest reserves of NG could well be in Russia since they get a higher percentage of NG from their fields than we do.
Yeah, now you've really got me confused.Oil and gas are not interchangable for a majority of people, particularly considering that most oil goes into transport,and most natural gas does not. Hydraulic fracturing is a process that allows what would normally be uneconomic volumes of oil, gas and water to be recovered to be economic.
And Russia, Qatar and Iran would be the three countries on the planet that have gas reserves and resources out the wazoo, and I'm not sure what Russian GOR's are from all their fields but I don't expect them to be that different from GORs in similar fields anywhere else on the planet. If in fact what you are referring to is GOR and not something else, which is where the confusion comes in because you haven't been very clear.
