Description
The process of petrographic analysis aims to help oil and gas experts in building a prediction model which would better characterize and explain the behavior of the hydrocarbon reservoir. However, making informed decisions regarding a good characterization requires exploration and integration of very large amounts of data presenting many challenges in which high dimensionality is the most important one. We present PetroVis, our visualization prototype which we developed with the goal of supporting the visual analysis of petrographic data. PetroVis incorporates the use of multidimensional visualization techniques coupled with statistical methods in order to enable identification, classification, validation and interpretation of petrofacies. We developed PetroVis continuously guided by the feedback and suggestions from our domain collaborator.
