Abstract
Summary This work proposes the use of stratigraphic forward modelling to test and quantify concepts about the evolution of the carbonate platform of a Pre-Salt field, as well as to use the results as trends for stochastic simulations of facies in geocellular reservoir models. The facies model was performed in three steps: (1) facies interpretation in the wells using rock data (core and sidewall samples) and image logs; (2) forward modelling simulation to control the carbonate reservoir geometry and low-frequency heterogeneities; (3) stochastic simulations of the facies, which aims to generate a high-frequency variability of facies and honour the well data. Subsequently, this final facies model, based on geological knowledge and geostatistic approach, will be the background for the propagation of the petrophysical rock properties (porosity and permeability).
