DIGITAL ROCK PHYSICS-BASED TREND DETERMINATION AND USAGE FOR UPSCALING

摘要

An example method includes acquiring two-dimensional (2D) or three-dimensional (3D) digital images of a rock sample. The method also includes selecting a subsample within the digital images. The method also includes deriving a trend or petrophysical property for the subsample. The method also includes applying the trend or petrophysical property to a larger-scale portion of the digital images.
