Abstract

The advent of 3D inversion packages for Resistivity and Induced Polarisation has meant that geophysicists are no longer constrained by survey arrays designed to produce manually plottable data to be interpreted by eye. 3D inversion processing means that there is no longer a need to place receiver and transmitter electrodes in a co-linear array. Electrode arrays can now be designed to optimise target definition and data collection efficiency.

The double offset pole-dipole array offers a way to collect large amounts of data efficiently and has superior inversion sensitivity and depth of investigation to standard arrays.
