Abstract
The present thesis deals with the characterization of the deep marine reservoirs of Sapphire field that is allocated at the west Mediterranean Nile Delta Egypt. The goal of the study has been achieved through an integrated approach between some of the petrophysiacl and sedimentological tools especially the advanced ones like NMR, FMI and MDT tools. This integrated approach involved three main stages of advanced analytical techniques. The first one deals with carrying an advanced petrophysical analysis, while the second one deals with structural framework delineation, sedimentological and depositional setting interpretation. Finally, the third ones deals with constructing a geostatic model showing the different characteristics of the studied reservoirs. The petrophysical stage included the implementation of two techniques, deterministic and probabilistic, to deduce the main properties such as net reservoir thickness, net to gross thickness, reservoir porosity and permeability, fluid saturation, hydrocarbon and water bulk volumes. This stage included the identification of the reservoir fluids as well as the delineation of the vertical and horizontal reservoirs continuity using MDT data, and at the end with the identification of the different reservoir dynamic rock units through establishing a new methodology using NMR log data. The structural, sedimentological and depositional setting interpretation were achieved through the using of (FMI) log data in integration with the available core data. The structural framework delineated though the interpretation of formation bedding over the image logs as well as minimum and maximum stresses determination using some evidences like washouts and either fracture or faults. Both of the sedimentological characteristics and depositional environment interpretation were depended on the FMI electro-facies that have been grouped and classified into facies association, which could reveal unique depositional units that can be linked to a certain depositional environment. The reservoirs geomorphology and the distribution of its petrophysical characteristics in three-dimension geostatsical models were constructed to get a better understanding of the overall properties of the studied reservoirs as well as getting the maximum volume of its hydrocarbon reserve.
