     "abstract": "Oil and gas well production parameters, including peakmonthly\r\nproduction (PMP), peak-consecutive-twelve month\r\nproduction (PYP), and cumulative production (CP), are tested\r\nas tools to quantify and understand the heterogeneity of reservoirs\r\nin fields where current monthly production is 10 percent\r\nor less of PMP. Variation coefficients, defined as VC=\r\n(F5-F95)/F50, where F5, F95, and F50 are the 5th, 95th, and\r\n50th (median) fractiles of a probability distribution, are calculated\r\nfor peak and cumulative production and examined with\r\nrespect to internal consistency, type of production parameter,\r\nconventional versus unconventional accumulations, and reservoir\r\ndepth.\r\nWell-production data for this study were compiled for\r\n69 oil and gas fields in the Lower Pennsylvanian Morrow\r\nFormation of the Anadarko Basin, Oklahoma. Of these, 47\r\nfields represent production from marine clastic facies. The\r\nMorrow data were supplemented by data from the Upper\r\nCambrian and Lower Ordovician Arbuckle Group, Middle\r\nOrdovician Simpson Group, Middle Pennsylvanian Atoka\r\nFormation, and Silurian and Lower Devonian Hunton Group\r\nof the Anadarko Basin, one large gas field in Upper Cretaceous\r\nreservoirs of north-central Montana (Bowdoin field),\r\nand three areas of the Upper Devonian and Lower Mississippian\r\nBakken Formation continuous-type (unconventional)\r\noil accumulation in the Williston Basin, North Dakota and\r\nMontana.\r\nProduction parameters (PMP, PYP, and CP) measure the\r\nnet result of complex geologic, engineering, and economic\r\nprocesses. Our fundamental hypothesis is that well-production\r\ndata provide information about subsurface heterogeneity\r\nin older fields that would be impossible to obtain using\r\ngeologic techniques with smaller measurement scales such\r\nas petrographic, core, and well-log analysis. Results such as\r\nthese indicate that quantitative measures of production rates\r\nand production volumes of wells, expressed as dimensionless\r\nvariation coefficients, are potentially valuable tools for\r\ndocumenting reservoir heterogeneity in older fields for field\r\nredevelopment and risk analysis.",
