 en Detection of Fractures for Groundwater Development in Oha Ukwu using Electromagnetic Profiling
Ugwu, S. A. & Nwosu, J. I.


Electromagnetic profiling technique was used in this study to detect fractures for groundwater development in Oha Ukwu Local Government Area in the Albian Asu River Geological Formation. The data showed that conductivity anomalies, 297-506mmho/m.was obtained along the fractured zone. Where the conductivity values did not change much, (12.3-37.9mmohm/m), the rock was not generally fractured, for instance, between the distances 0 and 800m; and 1000-1200m. It was discovered that the higher the peak, the deeper the rock fracture. This was confirmed from the cross section drawn from the manually contoured values of the data. It was further discovered that the producing water borehole along the traverse which coordinate is 007.966E and 06.466N and lies between 960 and 1000m situates within the fractured zone while the abortive wells fall within the non-fractured zone @ JASEM
