Asmari is a heterogeneous carbonate reservoir, which fractures play main role in hydrocarbon production. The main goal of present study is evaluation of FMS’s ability in detecting fractures and other geological features of Asmari formation. More than 380 m whole core that cut from Asmari described in order to extract structural features. FMS of this interval has also been processed and interpreted. Then, in order to evaluate and compare structural features on both core materials and image logs, the frequency logs (as frequency per 0.5 m) (for fractures, compactional features, beddings and anhydrite),orientation plots (for fractures and beddings) and aperture log (For open fractures) have been generated. Results checked by fractures data of seven wells (five image logs and two cores) of studied field and one well of neighbor field that obtained from core and image logs. Comparison of core and FMS revealed that they have excellent correlation for open fracture. FMS rarely detects filled fractures and faults of Asmari in studied well. It also is average in detecting bedding plains. Most of the 940 compaction features observed in core could not be recognized in FMS. Anhydrites in Asmari determined by FMS had good correlation with core.
