ABSTRACT: 168 core
samples data of two production wells in the Baltim North field were used to
identify the complex discrepancies in reservoir pore geometry which governing
the Abu Madi reservoir fluid flow properties. Permeability prediction from well
logs is significant goal when the core data is rarely available in most cases
because of its expensive cost. The hydraulic flow unit approach was used to
classify reservoir rocks according to its pore aperture size in the cored
wells. The predicted permeability was calculated from core porosity and core
permeability relationship for each flow unit. The difference between Neutron
porosity and Density porosity was recognized to distinguish different hydraulic
flow units. The higher difference indicates higher quality flow unit and vice
versa. For model’s verification the predicted permeability was plotted against
the laboratory measured permeability in all studied wells and shows highly
matching.
