Abstract:

The Egyptian government tends to rely on renewable energy sources in the framework of sustainable development plans, including the geothermal energy. Therefore, this investigation objective to reveal the distribution of the geothermal energy in term of u-pwelling heat flow over the Egyptian Red Sea district from magnetic data by assessing the depth to the bottom of the magnetic bodies. The spectral analysis method was applied to the magnetic data to determine this bottom. This method demonstrates that the area is characterized by an average Curie depth of 9.5 km. The calculated heat flow of this area (151 mW/m²) goes above the common worldwide heat flow. The consequences establish a general increase of the Curie point depth from 7km, close to the axial trough, to 15km at the western coast. The assessed heat flow varies from 92 to about 196 mW/m². The examination area has a high geothermal gradient and a high heat flow because of the rifting action of the Red Sea that causes an up-welling heat flow from the upper mantle. The results indicate that the area is suitable for hydrocarbon accumulation as a source of non-renewable energy as well as geothermal energy as a source of renewable energy.
