The offshore Nile Delta's Baltim gas fields contain extremely substantial gas condensate accumulations. Therefore, defining Pleistocene reservoirs (El-Wastani formation) and Pliocene reservoirs (Kafr El-Sheikh formation) is the primary objective of this research. A variety of data from five wells, such as gamma-ray, density, neutron, sonic, and resistivity wireline logs. These well logs are put together with seismic data, and a synthetic seismogram is used to find the right gas horizon interpretation for both of anomalies. Using seismic attributes while looking the existing seismic data makes it much easier for interpreters to learn more about the existing geological features. This investigation primarily aims to verify the presence of two potential gas anomalies, first is the structural attributes which include by applying seismic attributes in addition to conventional seismic interpretation. Seismic attributes are significant to ensure the two prospective gas anomalies by applying two different types of seismic attributes. First is the structural attributes which include discontinuity and fault likelihood (FLH), which are very important for fault detection. They are also important for examining the gas leakage to determine if the main fault is fully sealed, partially sealed, or non-sealed. The second is stratigraphic attribute, with different types. In this study, three stratigraphic attributes were applied: sweetness, reflection strength, which is a good tool for gas identification as high sweet points and high reflectivity; also, the third type of attribute is spectral decomposition, which is a good type for channel identification and determine of channel fairway as existence in the second Pliocene anomaly, which reflects the best place for drilling development wells. This study area is illustrated through seismic interpretation of 3D re-processed seismic data collected in 2018 and 5 wells data.

This study presents an integrated formation evaluation of the Middle Miocene syn-rift sandstones of the Hammam Faraun Member from southern Gulf of Suez. Core data, XRD, wireline logs and gas chromatography data have been utilized to assess the reservoir characteristics. Three lithofacies are identi ed from the cored intervals: i) ne to medium-grained massive sandstone (F-1), ii) low-angle cross-bedded ne-grained sandstone (F-2) and iii) coarse to very coarse-grained massive sandstone (F-3). The dominantly massive nature of the sand units with sharp erosive base and bottom rip-up clasts strongly indicates a high energy channel or fan deposit. XRD analysis exhibits quartz and feldspar to be the dominant constituents of these calcareous arkose. Montmorillonite and kaolinite are the major clay phases along with minor illite. Routine core analysis of a total of 168 core plugs indicates meso-to megaporous sandstones with porosity up to 28% and Kh up to 1171 mD. Permeability anisotropy analysis exhibit the dominance of primary depositional fabric and isotropic pores. Wireline log analysis yielded shale volume < 0.2 v/v, porosity ~ 0.18-0.24 v/v, and water saturation ~ 0.33-0.49 v/v. Various gas ratios (wetness, balance, character, and oil indicator ratio) estimated from the chromatograph data indicates the presence of liquid hydrocarbon within the studied reservoirs. The study concludes excellent reservoir properties in the Hammam Faraun clastic intervals of the Esh Elmallha area. HighlightsHammam Faraun reservoirs consist of meso-megaporous calcareous arkose.Massive sands with sharp erosive base and bottom rip-up clasts indicates a high energy channel or fan deposit.Wireline logs indicate poor shale volume and considerable hydrocarbon saturation.Gas chromatography data con rms the presence of liquid hydrocarbon.

Middle Jurassic reservoirs present challenges in the northern segment of the Western Desert due to geometric uncertainties arising from structural configurations, lateral facies variations, diverse lithologies, and heterogeneous reservoir quality. Consequently, this study employed an intricate approach, constructing detailed 3D geostatic models by amalgamating diverse datasets, including 2D seismic sections and digital well-logs. The focus of these 3D models was on the Khatatba Formation (Upper-Safa Member, Kabrit Member, and Lower-Safa Member) in Matruh—Shushan Basin in the North Western Desert. The objectives encompassed assessing hydrocarbon potential, precisely estimating reserves, formulating development and exploration strategies, and identifying prospective drilling locations. The resultant structural model revealed a compartmentalized region marked by major and minor NE–SW trending normal faults, establishing structurally advantageous locations for hydrocarbon trapping within the study area. Petrophysical analyses highlighted the promising potential of the Upper-Safa Member as a reservoir, featuring porosity values ranging from 10 to 18%, peaking in the northeast sector, volume of shale (Vsh) between 15 and 24%, water saturation (Sw) spanning from 18 to 53%, and increased sand thickness towards the eastern section. Similarly, the Lower-Safa Member demonstrated favorable reservoir attributes, including porosity values ranging from 10 to 16%, with higher values in the southeastern part, Vsh between 17 and 28%, and Sw varying from 15 to 47%. The study findings underscored the hydrocarbon potential in the northeast block of the study area for the Middle Jurassic Khatatba Formation. These insights contribute valuable information for decision-making in exploration and production endeavors within the basin.
