Incorporating seismic attribute maps in 3D reservoir models
- and others
We introduce a new geostatistical method to incorporate seismic attribute maps into a 3D reservoir model. The method explicitly honors the difference in vertical resolution between seismic and well log data. The method, called Sequential Gaussian Simulation with Block Kriging (SGSBK), treats the seismic map as a soft estimate of the average reservoir property. Using this method, the average of the cell values in any one vertical column of grid cells is constrained by the value of the seismic map over that column. The result is a model that contains vertical variability driven by well logs and the vertical variogram model and spatial variability driven by the seismic map and the areal variogram model.
