Tests of Simplified Conductivity Stratigraphy by Monte Carlo Analysis in GPFA-AB The simplification of well geology using the COSUNA approximation is tested by using Monte Carlo analysis to examine the potential differences of the thermal model outcomes for the COSUNA simplification compared to a full analysis of each well. For 77 wells, thermal model outcomes of the conductivity stratigraphy based on well details are compared to thermal model outcomes for the same locations if the COSUNA approximation is used instead. This memo first describes the approach of selecting a smaller subset of wells from the large collection to better understand the Basin's characteristics. Criteria were established for well selection based on availability of better lithology detail, multiple temperature-depth readings at appropriate depths, spatial distribution throughout the region of interest, etc. against which to test the COSUNA-based thermal model. The memo then describes the Monte Carlo simulation parameters. The results of the analysis are that the differences between the COSUNA stratigraphy with Carter conductivities and the detailed stratigraphy are generally minor when compared over the whole region.
