3-D digital rock image have recently become an important piece of information about the hydrocarbon reservoir properties. The goal of this project is to explore and employ machine learning as a tool to better understand the 3-D digital rocks from geometric measurement and features extracted from the image. Introduction This project applies machine learning to 3-D binary segmented images of the ...

The objective of this study was to establish a rock physics model of North Sea Paleogene greensand. The Hertz-Mindlin contact model is widely used to calculate elastic velocities of sandstone as well as to calculate the initial sand-pack modulus of the soft-sand, stiff-sand, and intermediate-stiff-sand models. When mixed minerals in rock are quite different, e.g., mixtures of quartz and glaucon...

Abstract The phase of CO 2 present in a saline reservoir influences the change pore geometry properties rocks and consequently transport storage integrity reservoir. In this study, digital rock physics was used to evaluate saturated with different phaseCO -brine under conditions. changes due -brine-rock interaction were quantified. addition compression, caused further reduction porosity by prec...

[1] Understanding the mechanical behavior of rock is critical for researchers and decision-makers in fields from petroleum recovery to hazardous waste disposal. Traditional continuum-based numerical models are hampered by inadequate constitutive relationships governing fracture initiation and growth. To overcome limits associated with continuum models we employed a discrete model based on the f...
