Land Magnetics

For land magnetic surveys, Excel owns and operates Overhauser GSM-19 Magnetometers with an absolute accuracy of ± 0.1 nT and a resolution of ± 0.01 nT. Land magnetic surveys are a non-destructive and cost effective geophysical technique. Excel has performed several land magnetic surveys for the mining, oil and gas exploration, archaeology and environmental industries for purposes including unexploded ordnance detection, magnetic observatory measurements, as well as geologic, archaeological and pipeline mapping. Recent land magnetic surveys were designed to evaluate large areas for mineral bearing ore bodies and oil-bearing sedimentary structures.
