Abstract: For each well of the plurality of wells, a plurality of model outputs are generated for the well. A range of productivity is determined for the well by plotting the plurality of model outputs in the form of a probability distribution function, projecting an actual production indicator result for the well onto the probability distribution function, comparing the actual production indicator result and the probability distribution function to identify a well production potential for the well, and determining a quality of the well production potential based on a plurality of categorization rules including a lowest quality category and a highest quality category. All of the wells in the plurality of wells are analyzed to identify wells in the highest quality category based on the determined quality of well production potentials for the plurality of wells for hydraulic refracturing.
