Petrophysical Uncertainty

What is your Petrophysical Uncertainty? How do you quantify a high and low case for your property predictions?


The attached PDF shows how to quantify core measurement uncertainty and Petrophysical uncertainty but also the uncertainty associated with up-scaling from core to log and log to 3D Seismic scale.


The presentation also addresses the uncertainty due to averaging, which is primarily used to populate properties in the 3-dimensional space.
