Reservoir Characteristics from Well Logging Records of Mamuniyat Formation, M Oil Field, NC115 Concession, NW Murzuq Basin, SW Libya

This study is concerned with Reservoir characteristics at M field, concession NC-115 in Murzuq basin sw of Libya. Mamuniyat formation is considered the first reservoir in the studied field M-NC115, sourced and sealed by Tanezzuft formation.Well recording operations have developed at the present time to become an essential and important part of drilling conclusions in addition to productive probing operations, which give us information about the well's productivity. Twelve wells were identified for this work scattered in the study area. A petrophysical assessment was achieved with interactive petrophysics software 2018. The results showed that the study Formation consists of sandstones with a small percentage of shale. The results also showed that the upper part of the studied reservoir at ((zones I and II)) is of higher quality than the lower part (zones IV). The reservoir thickness is about 960 ft in the north flank of the study area, and it is completely absent in the southwest flank of the study area. The results also illustrated that the average water saturation is 40%, the porosity is 12%, and the reservoir thickness is 560 ft.
