Summary:
The studied porous-cavernous carbonate rocks of the Khalah formation of the North-Western desert of Egypt are represented mainly by cavernous limestones, in the lower part of fine-grained chalky and marly limestones. Throughout the work area, limestones are blocked by younger sandstone calcareous with stratigraphic disagreement. In the roof of limestones, the weathering crust is represented by sections of scabrous rocks with loamy aggregate of 1 to 3 m in thickness. In the present study, two problems were solved: 1. Study of the pore space of limestones of the Khalah formation 2. The positions in the space of the zones of these rocks with different physical properties, characterizing permeability. The solution of these problems is connected with the subsequent construction of industrial facilities in the territory under consideration. To solve these problems, a set of geological and geophysical methods was applied.
