40 [Advertorial] overcame this problem by keeping the transmitter and receiver in symmetry. The heli XTEM gives much higher spatial resolution than fixed wing TDEM surveys, allowing detailed mapping of shallow to medium depth groundwater resources. In 2003, the United Arab Emirates commissioned the most comprehensive demonstration of the value of airborne geophysics in water exploration by flying a blind XTEM survey over an area of desert previously explored by drilling hundreds of bores at enormous cost. In just five days of flying and five days of processing, the survey produced over four million airborne electrical soundings, with each sounding having almost as much information as a borehole. The acquired data was processed into multiple maps, cross sections and 3D images that mapped out the fresh water resources in very high resolution never seen before. The whole survey cost less than just one of the hundreds of bores drilled using the traditional scattergun drilling approach. Since this demonstration the XTEM system has become part of mainstream groundwater exploration throughout Australia. As project water needs continue to rise to meet increasing scale efficiencies and the remaining groundwater resources become harder to locate, the ability to stay ahead of advances in airborne geophysical technologies will be the critical success factor for future water development.
