Conventional and Unconventional Gas
Conventional Gas refers to natural gas that can be produced from the reservoirs using some techniques like traditional drilling, pumping and the compression techniques. Natural gas is referred as conventional when it can be extracted from the Earth either through naturally occurring pressure, or pumping mechanisms. This is opposed to unconventional gas sources like shale gas, tight gas, and coal bed methane. Conventional gas tends to be less expensive and complex to extract than unconventional gas due to the usual nature of production techniques. Historically low natural gas prices have led to the popularity of its use for the power and heating.
