Abstract

The application of vertical magnetic gradiometer methods to hydrocarbon exploration was initiated some thirty years ago, by Pure Oil Co. (now Union Oil) and Aero Service Corp., using both helicopters and fixed-wing aircraft (Slack et al., 1967).

Both types of installation used two total-field sensors, with a vertical separation of 100 ft (30 m). For the helicopter version, both sensors were suspended on tow cables. For the fixed wing, one sensor was in a tail stinger and the second was towed below the aircraft. The magnetic interference of the aircraft on the stinger sensor was compensated for by passive means.
