A gravity transducer includes a particle system characterized by internal vibrations relating to its de Broglie wave, a resonant cavity for trapping the particle without holding it in a lattice structure; a source of a phonon wave, wherein the de Broglie wave and the phonon wave interact over a junction area; a power source for applying electrical power across the junction; a sensing system for measuring resistance, voltage, or current across the junction and for producing a sensed signal; and a recording system for recording the sensed signal. The transducer is used in a method of detecting potential hydrocarbon deposits, the method comprising: providing the transducer for sensing a change in a spatial orientation of gravity; flying the gravity transducer across the hydrocarbon deposit; sensing a change in spatial orientation of gravity to produce a signal indicative of geologic subsurface features, generally associated with hydrocarbon deposit; and recording the signal.
