... In determining inter-well connectivity analysis, the very first reference basis are well logs. Although carbonates are heterogeneous and their permeability may not be derived from porosity as easily as sandstones, their reservoir quality can still be determined from a conventional logging suite...

... Abstract The approach to handle the unresolved pores at 3D X-ray Micro Computed Tomography (μCT) images of core samples is developed. It enables a sufficient widening of digital rock studies for tight rocks. The μCT images of a low-permeable sandstone with a resolution of 1.2 μm/voxel have been...

... fingering for a better oil recovery. The effect of polymer addition to water is not only to increase the water viscosity but also to reduce the water relative permeability leading to more favorable mobility contrast. Skauge et al., (2014) , show the development of viscous fingering in a bentherimer...
