The tectonic position of Egypt in the northeastern corner of the African continent suggests that it may possess significant geothermal resources, especially along its eastern margin. The most promising areas for geothermal development in the northwest Red Sea-Gulf of Suez rift system are located where the eastern shore of the Gulf of Suez is characterized by superficial thermal manifestations, including a cluster of hot springs with varied temperatures. Magnetotelluric and gravity-reconnaissance surveys were carried out over the geothermal region of Hammam Faraun to determine the subsurface electric resistivity and the densities that are related to rock units. These surveys were conducted along profiles. One-dimensional (1D) and two-dimensional (2D) inversion model techniques were applied on the MT data, integrating the 2D inversion of gravity data. The objectives of these surveys were to determine and parameterize the subsurface source of the Hammam Faraun hot spring and to determine the origin of this spring. Based on this data, a conceptual model and numerical simulation were made of the geothermal area of Hammam Faraun. The numerical simulation succeeded in determining the characteristics of the heat sources beneath the Hammam Faraun hot spring and showed that the hot spring originates from a high heat flow and deep ground water circulation in the subsurface reservoir that are controlled by faults. These studies were followed by an assessment of the geothermal potential for electric generation from the Hammam Faraun hot spring. The value of the estimated potential is 28.34. MW, as the reservoir is assumed to be only 500. m thick. This value would be enough for the desalination of water for both human and agricultural consumption.
