Popis: This study focuses on one of the resistivity imaging tools owned by Schlumberger; Full-bore Formation Micro Imager (FMI). The objective of this paper is to analyze quantitative analysis that is carried out focusing on calculating the volume on clay volume and net-to-gross measurement. Clay volume in a thinly bedded interval was estimated based on the gamma ray log and one FMI trace (out of 192 traces). The gamma ray log data resolution is considerably lower than the FMI log to reflect accurate lithology changes in thinly bedded reservoirs. It has been found afterthought some calibrations and corrections on the FMI resistivity log, the new processed log is used for clay volume and net to gross calculation of the reservoir, indicating the potential of this log for analysis of thin beds. A comparison between VNG-NERGE, NORTH SEA WELL, NERWING and LAGIA-8, LAGIA, EGYPT indicates the calculation for shale volume at different intervals using FMI tools.
