N2  - The Central Luconia is one of the major carbonate province formed by 200 carbonate buildups with gas reserves of 63 Tcf. Structurally, the Central Luconia represents an area of low degree of structural deformation. It is located between areas of compression in south and subsidence in north. Carbonate sediments, were mainly deposited during the Upper Miocene (locally referred to as cycles IV and V). The reservoir quality of the carbonate sequence is largely controlled by dia-genesis. Hence, understanding of diagenetic process and products (pore types/cements) is of prime importance for predicting reservoir quality in the subsurface. In this study, about 1150 feet of core and 160 thin sections from well X are used to calculate the qualitative and quantitative description. The platform is grain dominated (32), dominant components are corals and foram-inifera (53). The dominant porosity type is mouldic (30), carbonates are poorly cemented with blocky equant calcite cement (35) having as dominant cement. However, diagenesis has altered these original minerals HMC (High Mg Calcite)/aragonite into LMC (Low Mg Calcite) and dolomite. Based on our observations, we can conclude that the platform was near to clastic source, highly dolomitized, porosity secondary in nature and coral facies are more diagenetically altered. Para-genetic sequence comprises of micritization, dissolution, dolomitization, cementation, mechanical compaction and stylolitization. © Pet Coal 2018.
