“…Despite the above features, the integration of scratching data and thermal profiling is of practical interest, particularly for unconventional formations [10,12,14,17,20,[41][42][43][44], since it allows us to refine the rock typing, quantitatively evaluate heterogeneity in strength and thermal properties, determine the locations of sampling for further laboratory studies (accounting for rock heterogeneity and thermal anisotropy), and establish for individual intervals the dependence of the "UCS-thermal conductivity" relationship to further use them for predicting UCS with the results of optical scanning.…”
