... in the Middle East. The results were largely influenced by reservoir heterogeneity and yielded large K v /K h ratios (greater than unity). Such data would need to be acquired on the same rock volumes for proper K v /K h ratios. In this work, permeability measurements were investigated using digital...

..., neutron-density and V-shale logs. Total (PHIT) and effective (PHIE) porosity were computed using the Neutron-Density algorithm in Techlog. The inputs were neutron porosity, bulk density and volume of shale. Prediction of permeability was log-based (as no reservoir in the field was cored). The permeability...
