Integrated Geophysical Studies for Mineral Exploration at Wadi El-Homer, Wadi Ranga Area, South Eastern Desert, Egypt.

The occurrences of mineral ore deposits and disseminated sulfides in wadi Dendekan are geologically thought to be associated with parts of the shearing fault and the alteration shear zone, which is composed of porphyritic rhyolites–dacite and metamorphosed volcanics highly fractured rocks occupying the all parts of the studied area. Mineralogical analyses that were done on bedrock samples of the oxidized and alteration zones indicated that there are several anomalous spots of minerals reached up to 3.6, 62.9, 87 and 202 ppm associated with Au, Ag, Pb and Zn respectively. Therefore, the magnetic, self-potential SP, resistivity and induced polarization surveys were applied and critically interpreted at south Wadi Dendekan area to delineate the mineral ore deposits in terms of depths and extensions. The interpretation of magnetic data was carried out using 3D Euler deconvolution, analytical signal and source parameter image techniques. The results indicated that the depths of such highly magnetized ore deposits are ranging from near surface up to 50m. However, the results of the SP survey showed distinctive negative and positive anomalies ranging from− 40 to 10 mV. Most of these anomalies occupy the shear, silicified zones, alterations zones and rock contacts. The Gradient resistivity map showed low resistivity values, less than 90 Ohm. m, with variable width. The induced polarization (IP)-chargeability data were measured in the time domain. The positive anomalies on the IP-chargeability map are clearly coinciding with the sites of alterations, shears and contact zones. Six 2D resistivity/IP imaging profiles that were measured along the …

Multisensor satellite data and field studies for unravelling the structural evolution and gold metallogeny of the Gerf Ophiolitic Nappe, Eastern Desert, Egypt

The gold mineralization located in the southern Eastern Desert of Egypt mostly occurs in characteristic geologic and structural settings. The gold-bearing quartz veins and the alteration zones are confined to the ductile shear zones between the highly deformed ophiolitic blocks, sheared metavolcanics, and gabbro-diorite rocks. The present study attempts to integrate multisensor remotely sensed data, structural analysis, and field investigation in unraveling the geologic and structural controls of gold mineralization in the Gabal Gerf area. Multispectral optical sensors of Landsat-8 OLI/TIRS (L8) and Sentinel-2B (S2B) were processed to map the lithologic rock units in the study area. Image processing algorithms including false color composite (FCC), band ratio (BR), principal component analysis (PCA), minimum noise fraction (MNF), and Maximum Likelihood Classifier (MLC) were effective in producing a comprehensive geologic map of the area. The mafic index (MI) = (B13-0.9147) × (B10-1.4366) of ASTER (A) thermal bands and a combined band ratio of S2B and ASTER of (S2B3+A9)/(S2B12+A8) were dramatically successful in discriminating the ophiolitic assemblage, that are considered the favorable lithology for the gold mineralization. Three alteration zones of argillic, phyllic and propylitic were spatially recognized using the mineral indices and constrained energy minimization (CEM) approach to ASTER data. The datasets of ALSO PALSAR and Sentinel-1B were subjected to PCA and filtering to extract the lineaments and their spatial densities in the area. Furthermore, the structural analysis revealed that the area has been subjected to three …

Reservoir Characterisation of the Jurassic Safa Formation, Shoushan Basin, North Western Desert, Egypt.

This study assesses the lithological and petrophysical properties of the Jurassic Safa reservoirs in western part of the Shoushan Basin, north Western Desert of Egypt. Composite logs from five wells from TUT and Salam fields were utilized to evaluate the different petrophysical parameters. Well log analysis, using Density/Neutron (D/N) dia-porosity and tri-porosity (M-N) cross-plots, have been used to determine the lithology and porosity of the studied reservoirs. Litho-saturation results reveal that the Lower Safa Member is composed of sandstone as a major lithological constituent and a few beds of limestone, with shale intercalation and calcareous cement, while the Upper Safa Member contains shale as the principal lithological component and a few beds of limestone, with sandstone bodies and calcareous cement. Effect of natural gas appears in some D/N cross-plots in both Members. Petrophysical parameters derived from vertical litho-saturation cross-plots were used to identify the most effective sand zones in each well. Movable hydrocarbon is found to increases mostly at the top and middle parts of the L. Safa reservoir and at the middle and bottom parts of the U. Safa reservoir. In terms of hydrocarbon potentiality, the studied reservoirs of Øeff, Vsh, Sh, Sw, net sand thickness, net pay and net pay to gross-sand were determined for the Lower and Upper Safa Reservoirs, respectively. Constructed iso-parametric maps of the Lower and Upper Safa reservoirs display that, the northern part; and the eastern and south-eastern parts of the studied fields are the most areas for future development, respectively.

Evaluation of groundwater sensitivity to pollution using GIS-based modified DRASTIC-LU model for sustainable development in the Nile Delta Region

The groundwater resources in the Nile Delta region are an important resource for freshwater because of rising water demand due to anthropogenic activities. The goal of this study is to quantify groundwater sensitivity to pollution in the Nile Delta by a modified GIS-based DRASTIC-LU model. In this study, we utilized two types of modified DRASTIC-LU models, generic and pesticide, to determine the groundwater vulnerability rates to contamination. The results of the generic DRASTIC-LU model showed that the research region, except for the northwestern part with moderate vulnerability of 3.38%, is highly and very highly vulnerable to pollution with 42.69 and 53.91%, respectively. Results from the pesticide DRASTIC-LU model, on the other hand, also confirmed that, except for the northwestern and southern parts with a moderate vulnerability of 9.78%, most the Nile Delta is highly and very highly vulnerable with 50.68 and 39.53%, respectively. A validation of the model generated was conducted based on nitrate concentrations in the groundwater and a sensitivity analysis. Based on the nitrate analysis, the final output map showed a strong association with the pesticide vulnerability model. Examining the model sensitivity revealed that the influence of depth to water and net recharge were the most important factors to consider.

Jurassic-Lower Cretaceous petroleum system of Faghur Basin, North Western Desert, Egypt

Different parts of the Lower Cretaceous Alam El Bueib (AEB) and the Jurassic Khatatba source and reservoir rock units in the Faghur basin, like in other basins in the north Western Desert, act as hydrocarbon sources and reservoirs. In the present study, well-log data from five wells in Phiops field and geochemical data from the Neith S-2X well from the neighbor Neith field together with reflection 2D seismic data of thirty (30) lines have been utilized to evaluate the Jurassic-Lower Cretaceous petroleum system in the Faghur basin and to give evidence for future hydrocarbon exploration and development in the study area. Source rock evaluation shows that several units from both Alam El Bueib and the Jurassic Khatatba shale source rocks represent good source rocks. Total organic carbon (TOC) values of the studied units of Alam El Bueib shale source rocks range from 0.27 to 6.39 wt.% that reflect fair to very good …

Petrophysical evaluation using well logging of the alam el-beuib reservoirs, Shushan basin, northern western Desert, Egypt

Petrophysical analysis of some of the Lower Cretaceous Alam El-Bueib reservoir units has been carried out using wireline logs from four wells representing two fields (GEB and APRIES) located in the western part of the Shushan Basin, northern Western Desert. Several petrophysical parameters were calculated and used in the petrophysical subdivision of the studied reservoirs, including shale volume (VSH), total and effective porosities (PHIT, PHIE), water saturation (SW), and hydrocarbon saturation (SH). Neutron versus density and M-N crossplots indicated that quartzose sandstone is the major matrix component with minor carbonates in some units. Furthermore, the litho-saturation crossplots indicated the existence of oil-bearing intervals, which are frequently associated with quartzose sandstones with low silt and clay content. Dispersed and laminated clays are detrimental to the reservoir quality as it blocks pore spaces, hence decreasing the hydrocarbon storage and flow capacities. Analysis of petrophysical data shows that the studied units have a good reservoir quality, with effective porosity values averaging 9% and low water saturation values of less than 35%. The most prospective reservoir intervals are found in the upper and middle reservoir units and are recommended for future exploration and development.

Stability and Volumetric Properties of Hot-Mixes Asphalt (HMA) Using Marble Powder Waste

The current study aims to evaluate the performance of hot mix asphalt (HMA) in terms of physical and mechanical properties using marble powder waste (MPW) as a substituting material for bag-house mineral filler. The marble powder waste is the by-product of the sawing and polishing processes of marble blocks that represent about 25-30% of the block volume. The marble wastes were characterized in terms of chemical composition, particle size distribution, and specific surface area using X-ray fluorescence (XRF), BT, and BET; respectively. To achieve the above objective, five asphalt mixes were prepared according to Marshal Mix Design procedure, using 0% (control mix), 25%, 50%, 75%, and 100% marble powder as a bag-house mineral filler replacement. The prepared asphalt mixes were subjected to the Marshall tests in terms of stability, flow, bulk specific gravity (Gmb), air voids (Va), void in mineral aggregates (VMA), and void filled with asphalt (VFA), in addition to the loss of stability (LOS). The results showed that there is an increase in the stability of asphalt mixes with increasing the (MPW). In the same line, the loss of stability decreased drastically with the addition of (MPW). Moreover, the results of flow, air voids, voids of mineral aggregate, and voids filled with asphalt achieved the requirements of the Egyptian Code of Practice specification (ECP) for binder mix.

Crustal Structure of the Nile Delta: Interpretation of seismic-constrained Satellite-based Gravity data

Interpretations of the tectonic setting of the Nile Delta of Egypt and its offshore extension are challenged by the thick sedimentary cover that conceals the underlying structures and by the paucity of deep seismic data and boreholes. A crustal thickness model, constrained by available seismic and geological data, was constructed for the Nile Delta by inversion of satellite gravity data (GOCO06s), and a two-dimensional (2D) forward density model was generated along the Delta’s entire length. Modelling results reveal the following: (1) the Nile Delta is formed of two distinctive crustal units: the Southern Delta Block (SDB) and the Northern Delta Basin (NDB) separated by a hinge zone, a feature widely reported from passive margin settings; (2) the SDB is characterized by an east–west-trending low-gravity (~−40 mGal) anomaly indicative of continental crust characteristics (depth to Moho (DTM): 36–38 km); (3) the NDB and its offshore extension are characterized by high gravity anomalies (hinge zone: ~10 mGal; Delta shore line: >40 mGal; south Herodotus Basin: ~140 mGal) that are here attributed to crustal thinning and stretching and decrease in DTM, which is ~35 km at the hinge zone, 30–32 km at the shoreline, and 22–20 km south of the Herodotus Basin; and (4) an apparent continuation of the east-northeast–west-southwest transitional crust of the Nile Delta towards the north-northeast–south-southwest-trending Levant margin in the east. These observations together with the reported extensional tectonics along the hinge zone, NDB and its offshore, the low to moderate seismic activity, and the absence of volcanic eruptions in the Nile Delta are …

Evaluation of hydrocarbon potentiality of the lower Safa reservoir, pepi field, Shushan basin, north Western Desert, Egypt

The Middle Jurassic Lower Safa Member serves as a hydrocarbon reservoir in Shushan Basin, North Western Desert, Egypt. The present work deals with studying the subsurface setting and reservoir properties of this member to assess its hydrocarbon potentiality in the Pepi field.  Seismic interpretation of thirty 2D seismic sections was used to determine the geometry and the detailed structural properties affecting this member. Well-log data available from five well-logs (Pepi-1X, Pepi-2, Pepi-5, Pepi-6, and Pepi-8) was utilized to determine the various reservoir parameters distinguishing the pay zone to highlight the promising locations for further exploration and development. Interpretation of the seismic data showed two master faults (F1 and F2) forming a half-graben block that trends NW-SE and NE-SW, respectively. These faults reflect the structural control of hydrocarbon accumulation in the Pepi field. Results of neutron-density cross-plots showed that the lithology of the studied Lower Safa reservoir is mainly sandstone with some calcareous cement. Vertical demonstration of the petrophysical data via Litho- Saturation cross-plots and lateral layout through the iso-parametric maps helped identifying the lateral variation of petrophysical parameters, reservoir thickness and to define the most suitable place for locating new productive wells. The estimated petrophysical parameters of the reservoir throughout the study area ranges from about 7.6 % to 11.3 % for effective porosity, from 1.8 % to 8.3 % for shale volume and from 47.3 % to 85.1 % for hydrocarbon saturation.  These results revealed that good reservoir parameters distinguish the Pepi field …

Application of Magnetic Susceptibility and Its Anisotropy in Deciphering the Tectonic Evolution of the Pan-African Belt of Egypt

The Pan-African belt (PAB) of Egypt outcrops mainly in the Eastern Desert and Southern Sinai. It occupies the northwestern sector of the Arabian-Nubian Shield (ANS) and lies at the northern continuation of the East African Orogen (EAO). The EAO comprises the low-grade greenschist facies lithologies of the ANS to the north and the deeper crustal equivalents of the Mozambique belt (MO) to the south. It is regarded by many workers to form a major suture zone delineating the oblique convergence (transpression) between East and West Gondwanaland. The PAB represents a complete succession of the Neoproterozoic basement encountered elsewhere in the ANS. It is recently interpreted as composed of a series of Neoproterozoic intra-oceanic arcs amalgamated during the climax of the Pan-African Orogeny c. 630 Ma. It consists of four major rock groups: high-grade gneisses and migmatites, arc-type …

Source Rock Evaluation of Some Mesozoic and Paleozoic Rocks, Faghur Basin, Neith Field, North Western Desert, Egypt

Faghur Basin is one of the most important hydrocarbon provinces inthe northern Western Desert of Egypt. Some of the Mesozoic (Alam ElBueib and Khatatba formations) and Paleozoic rocks at this basin wereevaluated as source rocks based on certain parameters including: thequantity, quality and maturation of the contained organic matter.PetroMode 1D software was used for the construction and prediction ofgeological and geochemical models. Results from organic geochemicalanalysis have clarified that the TOC, HI, S1, S2, %Ro and Tmax values ofAlam El Bueib source rock units range from 0.27 to 6.39 wt.%, 34 to114 mg/g, 0.12 to 0.38 mg/g, 0.23 to 4.3 mg/g, 0.58 to 1.07 % and 409to 450 oC, respectively. While for the Khatatba source rock these valuesrange from 0.41 to 30.09 wt.%, 27 to 155 mg/g, 0.1 to 0.53 mg/g, 0.15 to26.41 mg/g, 1.02 to 1.09 %, 363 to 454 oC, respectively. As for thePaleozoic source rock they are ranging from 0.53 to 4.83 wt.%, 52 to136 mg/g, 0.06 to 0.4 mg/g, 0.29 to 6.57 mg/g, 0.97 to 1.1 % and 406 to467 oC, respectively. Such results indicate that the Alam El Bueib sourcerocks are characterized by type (III) kerogen while Khatatba andPaleozoic source rocks are of type (III) kerogen with inputs of kerogentype (II). Burial history analysis indicates that most of these source rocksare mature and reached their maximum temperature at Neogene time.
