“…Separation of regional and residual aeromagnetic anomalies is considered very essential before any qualitative and quantitative interpretation process. The reason is that the observed aeromagnetic anomalies represent the combined effects of sources under different depth, density, or magnetic variation, especially for metallic deposits (Abdelrahman and Sharafeldin, 1996;Al-Rahim, 2016;Zahra and Nakhla, 2016). What really needs to be inversed is the mineralization-targeted or residual anomalies after removing the regional (background) anomalies and the neighboring interferences.…”

“…What really needs to be inversed is the mineralization-targeted or residual anomalies after removing the regional (background) anomalies and the neighboring interferences. There are some filtering techniques that have been applied to deal with this regional-residual separation issue, such as graphical separation (Gupta and Ramani, 1980), radial power spectrum analysis (Zahra and Nakhla, 2016;Elkhateeb and Abdellatif, 2018), match filter (Spector and Grant, 1970), preferential filtering method (Guo et al, 2013), polynomial fitting (Martínez-Moreno et al, 2015;Gabtni and Jallouli, 2017;Innocent et al, 2019), fast Fourier transform (Saada et al, 2022), and upward continuation (Eldosouky et al, 2022). However, there are no unique and absolute solutions for regional-residual anomaly separation.…”

Reduction of aeromagnetic noise and extraction of mineralization-related residual anomalies are critical for aeromagnetic data processing in mineral exploration. This study introduced a multifractal singular value decomposition (MSVD) method to remove the noise and improved the bi-dimensional empirical mode decomposition (BEMD) algorithm to extract residual magnetic anomalies. It is shown that MSVD and improved BEMD could effectively reduce the noise and extract residual magnetic anomalies. Then, a wavenumber–domain iterative approach is applied in 3D imaging of magnetic anomalies and gradients with depth constraints, which is a rapid tool for qualitative and quantitative interpretation of magnetic data and is suitable for rapidly imaging large-scale data. The 3D inversion result is verified by four geological sections along the regional tectonic directions and some drilling holes on the deposits. It is revealed that this proposed approach is practical and effective in dealing with aeromagnetic data interpretation and inversion for mineral exploration.

Lower Miocene rift sediments of the Nukhul Formation are one of the prominent hydrocarbon producers in the Gulf of Suez basin. In this study, we focused on the oil producing Nukhul sandstones of the Abu Rudeis-Sidri Field, located in the east central Gulf of Suez. Nukhul Formation is characterized by the prominent low amplitude seismic reflectors and represents the youngest identified reflector (Lower Miocene) in the study area. Petrophysical assessment was carried out using wireline logs to infer the reservoir characteristics. The Nukhul sandstone reservoir exhibits lower shale volume (< 0.1 dec dominantly), 0.07–0.16 dec total porosity and effective porosity up to 0.13 dec within the Nukhul sandstone interval. Bulk density-neutron porosity cross plot infers primarily sandstone matrix with the influence of carbonates, which characterizes the studied reservoir as calcareous sandstones. Spectral gamma ray data indicates montmorillonite as the principal clay phase along with minor kaolinite and illite. The calculated water saturation of the reservoir zone in the three productive wells ranges between 0.17 and 0.34 dec (i.e., the hydrocarbon saturation equals 0.66–0.87 dec). A small range of bulk volume of water (0.011–0.03 dec) indicates superior quality of the hydrocarbon-bearing sandstone intervals. Absence of productive sands in one of the studied wells, drilled in the hanging wall implied structural control on hydrocarbon accumulation in the study area. This study provides crucial insights regarding the quantitative petrophysical characteristics, reservoir quality distribution and hydrocarbon potential of the Lower Miocene Nukhul clastic reservoir.
