Oil/Gas and Mineral Exploration applications 

Our wide range of magnetic field measuring instruments has a number of uses in oil and mineral exploration, including: 

Time domain and controlled source electromagnetics TDEM/CSEM 

Whilst TDEM and CSEM traditionally rely on induction coil sensors as a receiver, in cases of very conductive targets, signal decay is very slow, and DC or very low frequency measurements are required. Fluxgate sensors detect this secondary field, and can measure over the frequency range from DC to 1kHz. Our magnetic fluxgate sensors can be used for this purpose – for ground work, and for borehole work. Some special types can also be used for offshore CSEM.
