N2 - On the basis of 12 wells, which are part of the Northeast Jabal al Hassouna wellfield (East Fezzan, Libya) of the Great Man Made River Project phase 2 a preliminary geophysical investigation of the aquifer in a certain area was done. The aim of the investigation was to get porosity and permeability information out of all wells from the available well log data and well reports. Well log data are very limited (resistivity, gamma, calliper). Based on a corrected Archie algorithm porosity could be estimated. Permeability was estimated by a combination of poro-perm- correlation and pumping test results. Furthermore logplots were used for correlation between the wells and for characterisation of the aquifer along 2 profiles. The result of interpretation discusses the type of porosity in the aquifer.
