Annotation

During diagenesis process, the upper Triassic sandstones Mulussa F reservoir have experienced multiple diagenetic transformations which have an important influence on the petrophysical properties of the reservoir, among them, the influences of the diagenetic / authigenic clay minerals precipitation. Conventional core analysis CCA data combined with petrographical observations have been used to characterize the upper Triassic sandstones reservoir parameters and to define the influence of the diagenetic clay minerals on reservoirs quality. Diagenetic clay minerals are found in a wide variety of morphologies as confirmed by Scanning Electron Microscope SEM analysis, and mostly are represented by; kaolinite, illite, chlorite and mixed layers of illite-smectite. The porosity and permeability of the upper Triassic sandstones Mulussa F reservoir were reduced by the platelets or booklet of the authigenic kaolinite which arranged as sub to euhedral blocky structures measure between 20 to 60 μm in length and partially or completely filled pore spaces. Some pores are occluded by the precipitation of the authigenic chlorites that are commonly occurred as grain coating, or pore-filling / lining phase. Authigenic illite and mixed layers of illite-smectite also played as an important factor in reducing the porosity of the upper sandstone reservoir where they are founded as grain coating or pore filling phase composed of well-crystallized lath-like blades (10 μm), and short fiber-like morphology partially filled the intergranular pore and has nucleated at the margins of detrital clay surfaces.
