Method for extrapolating the representativeness of the classes of the data of oil well wall rock lateral samples

Abstract

Method for extrapolating the representativeness of classes of data of oil well wall rock lateral samples comprises steps of a) selecting electrical log data and rock point data; b) determining maximum thickness and standard deviation tolerance which each electrical log will have to condition the expansion of the representativeness; c) verifying in the vicinity of each point sample to what extent the established criteria are met and determining that as the limit of the representativeness; and d) obtaining lithology result, or rock type, with the expanded representativeness of the point data. The method minimizes errors by automating processes and establishing quantitative criteria that take into account log data so that the representativeness is established. Considering adequate representativeness of rock point data is important—since characterization of the rock classes depends on a judicious and coherent expansion—if not performed incorrectly, all subsequent analyses and products will incorporate these errors.
