As the search for natural resources such as oil, gas and precious minerals intensifies, the demand for more sensitive exploration systems grows. Geophones used in oil and gas exploration will deliver greater and more accurate information with the inclusion of A-Metrics transducers in the devices – especially in the low frequency range, where typical geophones have poor sensitivity.

Gravity is often measured in increments of millionths of the earth’s gravitational field, or milligal (mGal). Over the earth’s surface this “pull” can vary as much as +/-65 mGal. The A-Metrics transducer, incorporated into existing technology, could measure variations in gravity pull to 0.0025 mGal, (2.5 microGal) or better.

Systems based on the technology have the potential to transform our ability to predict meteorological disturbances or natural catastrophes such as Tsunamis, Earthquakes or Volcanic Activity. Gravity Wave Sensors are another prime application of this technology. They would all benefit greatly from the high sensitivity and low cost of the A-Metrics transducer.
