Complex salt features resolved by integrating seismic, gravity and magnetics

Abstract

The seismic method continues to astound explorationists with the amount of detail that can be inferred from the data. New techniques such as turning wave analysis are allowing imaging of the base of complex salt features. In the past, gravity and magnetics data have been used only peripherally in mature salt basins, giving way instead to the greater imaging power of the seismic method. However, many complex geologic environments have not yielded all of their secrets to the 3-D seismic method. A revival is underway in the use of gravity and magnetics data to yield better geologic interpretations from seismic data.
