Description
Summary:The study of outcrops is one of the main ways of carrying out research in geology, because it offers direct analysis on the behavior of rocks. Thus, the study of analogous outcrops has been used by the oil industry, as they can be associated with other data and offer a more effective analysis in geological modeling of reservoir rocks. With the advancement of technology in recent years, the use of virtual environments has been gaining more space in geosciences, as they allow the user to analyse areas that are difficult to access and allow structural and geometric analysis of real-scale outcrops. Even though the use of Digital Outcrop Models (DOM) is becoming popular, the industry still suffers from a lack of software appropriate to interpret digital outcrops. In this paper we assess the performance of DOM to classify Lithofacies on out-crop of carbonate rocks in northeastern Brazil by using Mosis XP tools. Mosis XP is a software developed by Vizlab - X-Reality and GeoInformatics Lab specifically to perform DOM analysis and interpretation. Results confirm that texture and color attributes were satisfatory preserved in the virtual representation. Also, interpretation tasks were promising since allowed correctly identification of at least four distinct facies over the outcrop profile.
