Popis: Well-log (radioactivity, density and resistivity) analysis constitutes a stan- dard approach for inferring lithology from wells. However, due to inherent complex- ity of the signals (such as highly heterogeneous deep-water sedimentary sequences) lithology recognition is not straightforward. We used a rescaled range analysis, cali- brated with cores, to recognize lithological patterns from signal recorded along wire- line logs. The detected intervals coincide with zones of visual electro-facies associa- tions proposed by geologist well-log interpreters. In addition, we propose a rescaled range multifractal analysis to identify ranges of well-log signal complexities, which could be related to sedimentary process variations at specific stratigraphic order cy- cles.
