Desenvolvimento de uma metodologia computacional para determinação automática de petrofácies sedimentares em poços de exploração de petróleo

Abstract

To the characterization of hidrocarbon reservoir is strategically important both detection and mapping of it heterogeneity, as it can establish a relationship between porosity and permeability, defining both productivity and commercial character of a field of oil and gas. The sedimentary petrofacies are a set of characteristics that individualize a particular group of rocks, and their determination allows the inference of the heterogeneity of the reservoir’s heterogeneity. But this process is usually very long and not all information is harnessed, due to the large amount of data. Consequently, it becomes interesting change of use of manual methods for automatic analysis using computational tools. This work aims to present a computational method able to identify and separate them according to their common features. Thus, the method is able to assist the geologist/petrologist the task of identifying sedimentary petrofacies.
