Is it easy to use geostatistics for reservoir characterization or not? Is SGEMS able to reproduce reservoir geological characteristics in a 3D high resolution model? After years, Geostatistics has been allowing high resolution models generation to increase reservoir lithological detail. This work presents a straightforward methodology to create a facies model conditioned with the porosity model. Therefore, Open source geostatistics software was used to interpolate data. Rock type and porosity data, obtained from 26 well-logs of the Oriente Basin, were loaded in SGEMS. A high vertical and areal resolution 3D grid was built. Finally, 20 facies and porosity equiprobable models were generated. The model that better represents the reservoir characteristics was selected. The result is a high-resolution grid that represents the porosity conditioned to a facies model.
