虽然埃及没有丰富的新生代岩浆活动的特点，但其位于非洲板块东北角的位置表明，它可能拥有地热资源，特别是沿着其东部边缘。埃及利用热梯度/热流技术和地下水温度/化学技术进行了区域地热勘探。在热梯度/热流研究中，在钻取特殊热梯度孔之前，利用了现有油井井底温度数据以及现有钻孔中的地下温度测量值。地下水温度和化学数据被用来扩大直接地下热测量的地理范围。在一个非常有限的预算，区域热高已被发现沿着埃及东部边缘，并在该地区发现了局部热异常。已发表的地质资料表明，努比亚组的砂岩可能是地热流体的合适储层。新的数据表明，在苏伊士湾和红海沿海地区的水库中，可能会发现150/sup 0/C或更高的温度，该水库位于4公里或更深的深度。
Although Egypt is not characterized by abundant Cenozoic igneous activity, its location in the northeastern corner of the African plate suggests that it may possess geothermal resources, especially along its eastern margin. Regional geothermal exploration has been carried out in Egypt using the thermal gradient/heat flow technique and groundwater temperature/chemistry technique. In the thermal gradient/heat flow study, existing oil-well bottom-hole temperature data as well as subsurface temperature measurements in existing boreholes were utilized before special thermal gradient holes were drilled. Groundwater temperature and chemistry data were used to extend the geographic range of the direct subsurface thermal measurements. On a very modest budget, a regional thermal high has been discovered along the eastern margin of Egypt, and a local thermal anomaly has been discovered in this zone. Published geological information suggests that the sandstones of the Nubian Formation may be a suitable reservoir for geothermal fluids. The new data indicate that temperatures of 150/sup 0/C or higher may be found in this reservoir in the Gulf of Suez and Red Sea coastal zone where it lies at a depth of 4 km and deeper.
