A PROPOSAL FOR Geological MAPPING  OF FRACTURE ZONES FOR WATER SUPPLY

Charles T. Young,  Associate Professor of GeoP Engineering, MTU

We propose MS thesis research involving geological measurements of fracture zones near proposed and completed water wells.  The object is to improve  water well siting and production.

......Clearly, the depth of the hole and thus the cost of drilling could be reduced if  the location and orientation of the  fracture zone were estimated by instrumentation before drilling.

This technique ……radio signals in the frequency …...  The primary signal …… through the earth-ionosphere wave guide. It is refracted into the Earth and penetrates into the earth typically 100 to 500 meters in the rocks in the UP. The waves interact with electrically conductive water-bearing fractures and create a secondary signal. The primary signal alone creates a horizontal magnetic field. …..The data may be processed to create  a two-dimensional cross section of the subsurface, ………..    MTU owns a a geological VLF  receiver (Geonics EM-16 with a resistivity attachment)………..
