Upscaling with Bias 

Upscaling with Bias
Description: Diagram showing the effect of using bias when upscaling. To ensure cells with certain facies do actually get the petrophysical properties associated with those facies you should use bias during upscaling. In this case only the length of log corresponding to the facies in the upscaled cell is used in the averaging (log on the far right).
