In well logging, delineation of thin beds that contain reasonable amounts of hydrocarbon will enhance the total hydrocarbon potentiality of the area under evaluation. Most of thin beds are usually bypassed in case of the conventional wireline logging tools used, because of their low vertical resolution.
For better evaluation of the thinly bedded laminated sections and in order to maximize the hydrocarbon potentiality an integrated technique of resistivity anisotropy and nuclear magnetic resonance (NMR) were applied in this study. This approach is very useful, that minimizes the effect of the hydrogen index in the gas bearing sands.
The present study is applied on Port Fouad Marine field, Mediterranean Sea, Egypt, using the data available in the deep well PFMD-1 over the interval 2845-3300 m in the Tortonian Wakar Formation .The results of interpretation
show a better definition and counting of the thin beds from 12 m (by conventional tools) compared to 19 m from the
NMR-Resistivity anisotropy approach which can be considered as an added value to the formation evaluation process.
