Michael Pyrcz, PhD, P.Eng (daytum Founding Advisor) After the last lengthy post, this one is short, sweet, [slightly] technical, and vintage... As you can imagine, Facies / Rock type is an important decision for subsurface modeling. Below are a few comments, perspectives, and criteria on the topic. Comments and Perspectives: - When contemplating facies, the…

Uncertainty for Geoscientists, Data Scientists, and Engineers

Engineering, General, Geoscience, Geostatistics, Petroleum Engineering, Statistics , , , ,
Michael Pyrcz, PhD, P.Eng (daytum Founding Advisor) What is Subsurface Uncertainty? Uncertainty is not an intrinsic property of the subsurface. At every location (uα) within the volume of interest the true properties could be measured if we had access (facies, porosity etc.). Uncertainty is a function of our ignorance, our inability to observe and measure…
