  • Using gravity gradiometry in seismic interpretation in pre-SDM

    G. W. Coburn and J. Schneider

    U.S. production decline has spurred exploration efforts in increasingly difficult interpretation environments such as the deepwater Gulf of Mexico (GOM). To more accurately interpret seismic data in these areas, new technologies have been sought. One such technology is gravity gradiometry. Although gradient data has been extensively used since 1930, it was difficult and cumbersome because the data was collected using stationary measurements. In the 1970s, the U.S. Navy developed a moving gradiometer for positioning Trident nuclear-missile submarines. This technology was declassified in 1994, and is used in the energy industry today.
