Producing natural gas from shale gas reservoirs has gained momentum over the past few years in North America and will<br>become an increasingly important component of the world’s energy supply. A shale gas reservoir is characterized as an<br>organic-rich deposition with extremely low matrix permeability and clusters of mineral-filled “natural” fractures. Shale gas<br>storage capacity is defined by the adsorbed gas on the organic material within the shale matrix and free gas in the limited<br>pore space of the shale rocks. Horizontal drilling and hydraulic fracturing are the primary enabling technologies to obtain<br>economical production from the shale gas reservoir.
