Shale Gas Production Technologies


Gas contained within shale reservoir rocks is classified as unconventional gas reservoirs because the shale formation has low permeability. The reservoir is challenging to produce due to the lack of interconnections of the pore spacing. The gas cannot easily flow to the well in an unconventional reservoir and for this reason, shale gas reservoirs were not considered to be economical. In recent years, research and development of new technologies has made it possible to produce shale gas in an economically feasible fashion. The two major breakthroughs for shale gas production were hydraulic fracturing and directional drilling, which are typically used in combination to provide enhanced recovery ...
