Figurę 78 shows the resulted permeability map in Tubaen 1 after manipulations by BASRA. As can be seen, the contrast in horizontal permeability in this layer is preserved as the average value of the horizontal permeability is reduced by BASRA by a factor of around 0.67. It should also be noted that the initial variability between well points is just one realisation of an uncertain model, and seismic data have not been used as input to this modelling.
