On the Horizon… Air Quality Conventional resources generally exist in discrete, well-defined subsurface accumulations (reservoirs), with permeability values greater than a specified lower limit. Such conventional gas resources can usually be developed using vertical wells, and often yield economic recovery rates of more than 80% of the Gas Initially in Place (GIIP). By contrast, unconventional resources are found in accumulations where permeability is low. Such accumulations include “tight” sandstone formations, coal-beds, and shale formations. Unconventional resource accumulations tend to be distributed over a much larger area than conventional accumulations and usually require well stimulation in order to be economically productive; recovery factors are much lower — typically of the order of 15% to 30% of GIIP” (MIT, 2010).
