3D reservoir property modeling is one of the most important steps in fluid flow simulation. A more accurate model would provide a more realistic reservoir simulation. In this study, four different geostatistical approaches, including Kriging, collocated cokriging, sequential Gaussian simulation (SGS), and Cosimulation were applied to well data for 3D porosity model building. Initially, Kriging method was based only on well data and utilized for porosity estimation. Then, seismic acoustic impedance data as a secondary seismic attribute was used in collocated cokriging algorithm for 3D porosity modeling. Kriging and collocated cokriging-based SGS approach were also used for 3D model building. The cross validation of all the four approaches revealed that the best model obtained using co-simulation with secondary data.
