... gradient equipped 12 MHz NMR spectrometer. The experimental technique begins with carrying out as-received NMR scans on shale core plug samples to measure the amount of water and oil in the samples. Micro-CT scans are used to identify and reject plug samples that have micro-cracks. These samples...

This correlation allowed us to generate a synthetic porosity log of millimeter resolution. After that, the length scale was increased by moving...

... different scales (core plug measurements, log data and well test data). On a well test scale, permeability is influenced by larger scale heterogeneities, such as lateral changes in depositional facies, dipping beds and faults. In this study, we demonstrate that the use of small and medium scale process...
