Understanding the size of the inherent variability among wells is crucial.  It directly effects royalties paid.  It can easily account why your neighbors check is twice yours.  We have developed a series of programs to identify performance of thousands of wells.  This is done each month for all unconventional wells in PA.  We are sharing some these results to provide a realistic view of the variability among wells even on the same pad.  Take a look, this is real information.  In life (and the gas well business) there is no substitute for luck.
