Analysis of reservoir petro-physical parameters by PNL Saturation Log

Abstract

The purpose of this work was to introduce the tool used, and the summary of the information it gives us in the field, and the way to convert it into analytical results. so we can intervene in the well in a good way. The analysis was to evaluate and calculate the water saturation and compare it with the initial water saturation from open hole data in order to evaluate and monitor the change of the hydrocarbon / water contact using RMT tools. The results show the Dynamic Sigma Envelope overlaid with the Sigma curve used as hydrocarbon identification. The position of the Sigma (SGFC) curve between the water Line (blue) and hydrocarbon Line (green) determines the water saturation.
