Gravity gradiometry resurfaces

Gravity gradiometry is a Gulf Coast exploration technique that records gravity gradients, which directly recovers sharp signals over the edges of structures. Thus, the concept of gravity gradiometry is 3-D gravity. Gravity gradiometry anomalies reflect the edges and shapes of sources rather than just mass distribution. Three-dimensional gravity gradiometry is a `stealth' technology developed by Bell Aerospace for the United States Navy Trident submarine program. This technology offers the possibility of imaging density contrasts beneath salt to much higher resolution and accuracy than previously possible. It can be used to track the movement of hydrocarbons as production proceeds in oil fields.
