Abstract: A computer-implemented method/arrangement for rapidly assessing operable conditions of each constituent tool of a MWD tool string between two consecutive downhole runs of a drill string. The method includes filtering binary data downloaded from a recently pulled MWD tool string for data sets that each represent conditions indicative of the operational condition of each of the several tools of the MWD tool string. For each of the data sets, a processing algorithm is selected from a store of predetermined algorithms, based on characteristics of the respective data set. Each data set is substantially simultaneously processed with the algorithm selected for that data set. Based on respective tool-condition data output by each algorithm-processed data set, determining whether the tool that corresponds to the respective data set meets a predetermined operational capability requirement or threshold to be operated in a subsequent run downhole with the drill string.
