Integrating conventional and digital rock physics

Understanding the relationship between different petrophysical variables as function of stress is an important goal in core analysis. Integrating digital core analysis and conventional measurements in a way that measurements are made on the same scale allows a direct comparison of experiment and numerical simulation. If boundary conditions for both experiments are matched and measurements agree, the solution of the numerical problem provides additional insights by considering categorical variables, over which field variables might be averaged. The approach is illustrated by full scale calculations on reservoir core plugs, targeting permeability as function of stress conditions, quantifying the contribution of micro-porosity to relative permeability, and by local analysis of NMR responses with applications to rock typing.
