Geological investigation of the Upper Part of Memouniat Formation in Well I1-NC2, Ghadames Basin.
Journal Title: Libyan Journal of Engineering Science and Technology - Year 2022, Vol 2, Issue 1
Abstract
— Memouniat Formation proved to be a good reservoir in Concession NC2, containing gas and condensate at its upper part. The Memouniat clean sandstone units are anticipated good percent porosity and an average permeability value. The porosity and permeability decreased in some parts of studied well I1- NC2, The core samples and thin-sections were described shows grain size is generally medium in the upper part, and it is going to be fine sized in the lower part. The oil shows are only presented in the upper sixteen feet. The logs, used are Gamm Ray, Neutron Porosity, Bulk Density, Density Porosity, shows the section is sandstone interlaminated with shale. The bulk density increase with presence of shale, whereas the density and neutron porosities decrease. In the lowermost two feet the FMI image shows the shale lighter than in the layers above, because theit has more organic matter as it is shown in the thin sections. Compaction in sediment of Memouniat Formation it clear and obvious, represented in the wavy sutured styolties, and it is common in the lower part of core sample in the study well.
