The wealth of data on infill/step-out wells in the Western Canadian Sedimentary Basin (WCSB) implicitly includes clues to various reservoir characteristics, but techniques for evaluation were not obvious to us. We tried different ways of deriving meaningful insights and present three examples here. We compared the values of the average and the median performance parameters for specific populations of wells. Generally, the average rate was larger than the median. We also prepared frequency plots and their representation on the normal (standard deviation) scale for the wells in each group. From these plots, we were able to characterize teh lateral hetero-geneity of the reservoirs. These could also the used in analyses of risks in future projects. Risk analysis can also he aided by other features of frequency distributions. A rate-cumulative production plot was also helpful in determining acceleration and incremental reserves benefits resulting from infill drilling.
