Detection of boulder using GEM-2 EM system based on three-dimensional inversion algorithm

The granite body, or referred to as boulder, that shows high resistivity in the near-surface is a common geohazard in pipeline construction by trenchless technology. The GEM-2 system using small coils as the transmitter and receiver (Tx-Rx) has been widely used to delineate the low resistivity targe...
