Designing and manufacturing detectors used for deepwater oil and gas exploration can be very challenging. Detectors used for this purpose; need to have great accuracy and reliability in detecting extremely low frequency EM signals (as low as I kHz). Often these Electromagnetic (EM) waves to be detected have a diminished capacity (poor signal to noise ratio/ SNR) due to the very long depth (more than 2500m) they travel beneath the seafloor to reach the potential hydrocarbon reservoir
