Computational Intelligence Techniques and Phylogenetic Trees for Identification of Sedimentary Petrofacies

Anais do XV Encontro Nacional de Inteligência Artificial e Computacional (ENIAC 2018), 2018
The heterogeneities are characterized by several sedimentary petro- facies. Petrofacies identification involves manual processes and time-consuming analyses. The study of the diagenesis has been encouraged by petroleum companies, in order to understand the distribution of porosity in sandstones.
