“…The gamma-ray logs obtained from the Abu Roash G-5 reservoir reveal distinct patterns characterized by boxcar (or blocky), serrated, and cylindrical themes, as shown in Fig. (4). The gamma-ray levels of this facies range from 30 to 150 API units, with an average thickness of 25 meters.…”

“…Rock typing and petrophysical characterization are fundamental aspects of reservoir characterization and modeling in petroleum exploration and development [1,2]. These processes play a crucial role in understanding the properties and behavior of reservoir rocks, which are essential for optimizing oil and gas production strategies [3][4][5]. Reservoir rock typing involves classifying reservoir rocks into distinct types based on their petrophysical and geological characteristics that influence fluid flow.…”

Rock typing and petrophysical characterization play a vital role in constructing reservoir models for petroleum exploration and development. This study focuses on evaluating the petrophysical characteristics of the Late Cretaceous Abu Roash "G" Reservoirs at the East Alam El Shawish field in Egypt's Western Desert. The study involved five vertical wells and employed various techniques and analyses to investigate the reservoir. Lithology determination utilizing well logs and core analysis helps identify the lithology types and corresponding porosity of the Abu Roash "G" reservoirs. Sandstone and limestone lithologies with varying porosity ranges were identified, along with the influence of shale on neutron porosity values. Facies analysis of the Abu Roash "G" Member identified seven lithofacies types, categorized into shallow marine and deeper marine depositional environments. The petrophysical analysis involves evaluating gamma-ray logs, porosity, permeability, flow zone indicator (FZI), and reservoir quality index (RQI) values for each lithofacies type. This analysis classifies the core samples into seven reservoir rock types (RRT1 to RRT7) based on petrophysical attributes, providing a clear classification of the Abu Roash "G" reservoir interval. RRT1, RRT2, and RRT3 exhibit the highest reservoir quality, while RRT4 and RRT5 indicate moderate reservoir quality. RRT6 and RRT7 exhibit low reservoir quality due to unfavorable petrophysical behavior. The findings of this study provide valuable insights into the Abu Roash "G" reservoir, including its lithofacies, reservoir properties, and depositional environments. This knowledge is crucial for reservoir characterization and optimizing oil production strategies in the region.

“…After a certain period of rifting, Africa and Arabia were separated from each other by the Dead Sea Transform that allowed continued extension in the Red Sea and abortion of the Suez Rift. (Hamimi et al, 2019) The stratigraphic succession of the Gulf of Suez rift basin is divided based on Peijs, 2013 into five distinct tectonic mega sequences separated by regional unconformities that mark the onset and end of a successive phases of the basin forming processes. Megasequence 1 stands for Paleozoic age.…”

Kareem Formation is one of the Gulf of Suez's most significant hydrocarbon resources. It makes a substantial contribution to Egypt's overall oil production especially in Morgan and Badri fields. Kareem sand reservoir is deposited as a fan-delta environment, which erodes the high rift shoulders and deposits in the Basin. The present work deals with the petrophysical evaluation of Kareem Sand Reservoir at GS277 Oil Field which is the only oil reservoir in the field. Comprehensive well log analyses techniques were applied for a three-selected well in GS277 oil field. Those wells are named GS277-1, GS277-A4 and GS277-A5. The minimum suite of logs consisted of gamma ray, density, neutron, and resistivity logs; all the log data are in the form of LAS files. Specialized software was used for the petrophysical evaluation of Kareem sand reservoir in this study. In this paper , the essential petrophysical parameters were evaluated such as volume of shale (Vsh), effective porosity (Øeff) and water saturation (Sw). Also, cross plotting techniques are used for water resistivity (Rw) calculation and lithological identification for Kareem reservoir in the study area. The derived parameters from the petrophysical evaluation were used to calculate the standard tank oil in place (STOIIP) in Kareem sand reservoir in the study area. From the outputs of the petrophysical evaluation, it was found that Kareem Formation is a good reservoir rock in most intervals, where the interpretation of the well logging data indicates that the porosity ranges from 16% to 20% , shale content ranges between 5% to about 7%, water saturation from 20% to about 30%, and Net pay thickness ranges between 20 ft to about 50ft. The analysis of Lithological Identification cross plot for Kareem Sand reservoir indicates the presence of mixed lithology composed of sandstone and limestone. Petrophysical Analysis for Kareem Sand Reservoir in GS277 field indicate an enhancement for the reservoir properties towards GS277-A4 and GS277-A5 wells which may be highlight an opportunity for drilling a development well to maximize oil recovery from the field. Standard Tank oil in place (STOIIP) for Kareem sand in GS277 Field is calculated depending on the derived petrophysical parameters. The STOIIP ranged from 15 to 20 MMBO which highlighted a huge amount of hydrocarbons that is under developed.

Deciding on the next wellbore site for field development in oil and gas exploration is a process involving risks and large investments. Selecting a more accurate location based on hydrocarbon migration is one of the ways to reduce the risk in the operations. This study provides an overview to evaluate the pore pressure for main reservoirs in the Belayim oil land fields. These reservoirs are included in the Miocene Belayim, Kareem, and Rudies formations. Calculation of corrected drilling exponent (Dxc) is used in the present research based on electric logs. These calculations specify the pore pressure values and are used to make subsurface mapping that is utilized to observe the migration paths. The study revealed high to low pore pressure in the northeast-southeast trend in Belayim and Kareem formations in the study area. However, the high to low pore pressure trend is inversed and changed to northeast-southwest. Better locations of the field development are located in low pore pressure zones.
