Abstract Immense potential of shale gas to supplement domestic energy needs and the recent engineering strides in multi- staged fractures in long horizontal well laterals have inevitably increased interest in exploitation of such plays across the country. However, because of the continuous nature of these plays, the production potential can change significantly from one location to the other often within close proximity. For a project to be economically viable, under downward price pressures, large number of wells in multi-well drilling campaigns needs to produce commercial quantities of gas. Not surprisingly, numerous attempts are being made to type-cast mineralogy, organic contents, fracture design and completion opt
