Survey Design for the Borehole Induced Polarization Method: A Modelling and Inversion Study

The Induced Polarization (IP) method of exploration geophysics can sense the depth, size and

composition of certain metallic ore bodies. Measurements from within boreholes that surround an ore

body can help determine its size and hence its economic worth. Such geophysical methods of

determining the economic viability of a deposit are cheaper than doing so by drilling boreholes. Abitibi

Geophysique, inc., offer as a product to the mineral exploration industry a novel way of carrying out a

borehole IP survey. Abitibi Geophysique can make measurements using any locations within any pair

of boreholes that are available. However, there is a redundancy of information: doubling the number of

measurement locations, while doubling the length of time for a survey and hence its cost, doesn’t

necessarily provide twice the information about the ore body. The goal of this project, therefore, is to

determine the measurement configuration for Abitibi Geophysique’s borehole IP surveys that provides

the most information about an ore…
