Abstract
On this work we present a method to discriminate the pores shape in a carbonate rock using the Kuster and Toksöz model, like so, the determination of dolomitization process using laboratory samples characterized with the Digital 2D Imaging Analysis.
We conclude that is possible using the Kuster and Toksöz model to classify the distinct pore shapes, like spheres, needles, and Penny-Shaped Cracks and determine their dolomitization process using a graph of velocity versus porosity for carbonated rocks with presence of dolomite. On the other hand, we observed that is necessary to refine the interpretation with the Digital 2D Imaging Analysis, given that, there is not correspondence with certain geometries in this work. And finally, we observed that is necessary to add more curves like ellipsoids in our graph to improve the interpretation of the pore shapes and including the samples that were not characterized with the curves presented on this work
