APPLICATION OF WELL LOGGING METHODS TO ESTIMATE THE DEPTH AND THICKNESS OF DEEP AQUIFER (ZONE G) OF THE GEOLOGICAL SECTION IN THE IN THE NORTHERN PART OF EL-BAHARIYA OASIS (WESTERN DESERT, EGYPT)
Seven well-logs have been studied to assess the deep groundwater aquifer (zone G) in the Northern part of El-Bahariya oasis, Western desert of Egypt. The most important results of this study as follows: The depth of zone D in the study area is ranging from 530m to 785m and its thickness ranging from 67m to 170m. Zone D consists of Sandstone or Sandstone with minor layers of clays. Readings of short, long potential probes and GR in well-logs against zone G is ranging from 36 to 681 Ohm.m, from 69 to 1369 Ohm.m and from 10 to 52 API (Respectively). The best place for drilling new well is located at western part of the study area.
