“…In the last decade, applications in reservoir characterization are on the rise, with solutions being deployed on several fronts of machine learning (e. g. regression, classification, clustering, anomaly detection). Some selected works in the Brazilian Pre-Salt include automatic facies classification (Bize-Forest et al, 2018;Ferreira et al, 2019;Valentin et al, 2019, Camargo et al, 2022, reservoir property estimation Valentin;Ferreira et al, 2021;Babasafari et al, 2022), synthetic well-log generation , and support to drilling operations (Duarte et al, 2018). Some of these methods are further expanded in the next section.…”
