2020-Applied Petrophysics and Statistics - RILS - V20.11


The purpose of this skill level course is to provide the participants with an understanding of how petrophysics and statistics are integrated.  The course can be delivered as a remote delivery, a public or customized for a client.  Often the primary objective of reservoir petrophysics is to provide numerical transforms for total porosity, effective porosity, absolute permeability, lithology, defining petrophysical rock types  and creating a saturation height model.  It is important that investigators, know how to evaluate various statistical techniques and use various methods, because these numerical transforms are used as the basis for building static and dynamic 3-D models.  To be a successful reservoir petrophysicists, you must understand statistical distributions, various averaging methods, smoothing, curve fitting and regression methods. Further, it is necessary to understand when a dataset has statistical significance.
