ABSTRACT

Borehole geophysical measurements were carried out inside 18 exploratory water wells drilled at Maghara area, North Sinai. Qualitative interpretation of well logging data showed that there are two different aquifers in the  studied area, the first is found at Wadi El Masajid and the other at Wadi El Safa.

The first aquifer is located within the fracture limestone of Masajid Formation, Jurassic Age, the salinity of  its groundwater range from 1700-6000ppm, and the static water level varies from 118-120m below ground level.

The second aquifer is located within the Safa Formation, Jurassic Age, inside two types of rocks, fracture limestone, and coal bearing sandstone beds. The salinity of groundwater varies from 10000-15000ppm, while the static water level changes from 2.5-94m below ground level.
