Tight gas
From Wikipedia, the free encyclopedia
Tight gas is natural gas produced from reservoir rocks with such low permeability that massive hydraulic fracturing is necessary to produce the well at economic rates. Tight gas reservoirs are generally defined as having less than 0.1 millidarcy (mD) permeability.[1] Tight gas is considered an "unconventional" source of natural gas
Rock with permeabilities as little as one nanodarcy, reservoir simulation may be economically productive with optimized spacing and completion of staged fractures to maximize yield with respect to cost.[2]
