. The FTG survey is an airborne survey that aids significantly in the structural mapping of prospective hydrocarbon basins. Using a converted DC-3 aircraft, Bell Geospace will fly a dense grid of flight lines to measure small changes in gravity caused by changes in density of subsurface rocks. This survey method has been used successfully in Africa and contributed to recent oil discoveries in Uganda and Kenya.
