The Eastern Mediterranean region, extending from the Offshore Nile Delta Cone of Egypt to the Levant Basin, is a confirmed hydrocarbon rich territory with several giant gas discoveries. Numerous gas fields have been discovered in the Miocene reservoirs within the Nile Delta Cone, and in the Levant Basin. The Miocene sedimentary sequences in this region are extremely heterogeneous, consisting mainly of turbiditic slope deposits, channels, and basin floor fans that were capped by evaporites during the Messinian Salinity Crisis. As a result, there is ambiguity regarding the seismic characteristics and interpreted attributes of this heterogeneous section. The study area is located in the Offshore North Sinai Basin, where a thick Early Miocene section was deposited midway between the Nile Delta province that includes El-Fayrouz discovery and the Levant Basin which includes Tamar, Tanin and several other discoveries. This study uses quantitative seismic interpretations methods, such as amplitude variations with offset (AVO), fluid replacement modeling to assess the seismic acoustic impedance trend with depth. Also, determine the seismic amplitude response for the brine and gas sands reservoir of the Early and Late Miocene section, to link the unexplored study area within the North Sinai Offshore basin with the explored Nile Delta and Levant Basins. In addition to evaluate direct hydrocarbon indicator (DHI) of the diming seismic amplitude that is compatible with the structure last closed contour of the Syrian Arc anticline of the Early Miocene reservoirs (EMT-1 prospect). Different ventages of 2D & 3D seismic data, 6wells and different published data used in this study. The quantitative interpretation shows the pitfalls of the acoustic impedance trend and seismic response dependency on depth for gas and brine sand which lead to drill EMT-1 dry well. Also, the fluid replacement, P-wave velocity (Vp) and density (ρ) modeling confirming that the seismic diming amplitude is due to seismic processing uncertainty, which solved by readjust the overburden Messinian salt processing velocity model. This research concluded that the seismic quantitative interpretations were successfully used to assess the acoustic impedance versus depth and DHI pitfalls., also, assess the processing workflow that could enhance the seismic image.

This study aims to overcome the problem of unexpected hydrocarbon non-potentiality detected in Alam El-Bueib (AEB) member in Aman field. To achieve this objective, the structural framework and petrophysical analysis of the studied interval is carried out using seismic and well log data, respectively, then using the fault-seal analysis technique to assess the availability of the main fault dissecting AEB Formation to trap hydrocarbons. Structure depth contour maps and 3D structural model are constructed for illustrating the main structural features to assign and evaluate the most promising locations of closures favorable for hydrocarbon trapping. AEB III-E shows a general dipping to the northwest and south, constituting a horst fault-block dipping to the northwest. These structural settings are mostly three-way dipping and occasionally four-way dipping closures and accomplish the conditions for trapping of hydrocarbons. AEB III-E sandstone shows a porosity of 14 % to 16 % and water saturation near to 100 %, as reported by JASMIN-1X (J-1X) well. Fault seal analysis revealed that the main fault dissecting AEB Formation near J-1X well represents a leakage zone for hydrocarbon movability and its un-trapping in the location around the well. Finally, due to the good quality of AEB Formation in the study area ant its surroundings, a prospects prediction routine is carried out to search for other prospects. Two prospects are predicted which may be more favorable for hydrocarbon trapping.

The present study deals with petrophysical analysis to evaluate the hydrocarbon-bearing reservoirs in the Karama field, East Abu Gharadig basin Northern part of the Western Desert. Some wells which spread around the Karama field are being investigated and studied to determine the different petrophysical characteristics of the Upper Cretaceous Upper Bahariya and Abu Roash "G" reservoirs. This analysis indicates the presence of significant hydrocarbon potential in the Upper Bahariya and Abu Roash "G" reservoirs at different depth intervals. The well log analysis involves data editing, data verification, and lithology, porosity assessment using a density-neutron cross plot. The density-neutron cross plots indicate that the Upper Bahariya reservoir is mainly sandstones with some calcareous cement. Abu Roash "G" reservoir is mostly composed of limestone with some sandstone, shale, and siltstone lithology. The shale volumes are 10-19 % and 11-18 % in the Abu Roash "G" and Upper Bahariya reservoirs respectively, and the effective porosities are 14-20 % at the Abu Roash "G" while reaching 12-16 % at the Upper Bahariya reservoir, implying good reservoirs quality. Petrophysical parameters of the Abu Roash "G" and Upper Bahariya reservoirs are illustrated on iso-parametric maps to delineate the most effective locations with good hydrocarbon potentialities. The iso-parametric maps such as net pay, effective porosity, and hydrocarbons saturation show an increase in the southern parts of the study area especially in Abu Roash "G" reservoir, while the Upper Bahariya reservoir shows an increase in the north-western parts. This analysis gives necessary knowledge about the distribution of fluids within reservoirs.
