Gas that is trapped in very impermeable rock or sandstone. It can be extracted by fracking

Unconventional natural gas that's trapped in hard rock, sandstone or limestone formations that is impermeable and non-porous.

Natural gas produced from relatively impermeable rock.  Getting tight gas out usually required enhances technology applications like hydraulic fracturing.  The term is generally used for reservoirs ot [..]

gas found in sedimentary rock that is cemented together so tight that flow rates are very low. Extracting tight gas usually requires enhanced technology like"hydraulic fracturing" where fluid is pumped into the ground to make it more permeable.

Is natural gas trapped in a highly mixed mineralogy sandstone, shale, or limestone formations which has very low permeability and porosity. While conventional natural gas accumulations, once drilled, contain gas that can usually be extracted quite readily and easily, a great deal more effort, including hydrofracturing, has to be put into extracting [..]

Similar to shale gas but is trapped in other types of low permeability rock. Reservoirs require artificial fracturing to enable the gas to flow. Horizontal drilling and hydraulic fracturing are also used to develop such resources.

Gas produced from a relatively impermeable reservoir rock. Hydrocarbon production from tight reservoirs can be difficult without stimulation operations. Stimulation of tight formations can result in increased production from formations that previously might have been abandoned or been produced uneconomically. The term is generally used for reservoi [..]

Natural gas that is contained between dense rock layers that prevent it from flowing easily.
