Abstract

Summary

Accurate seismic imaging in depth domain is strictly related to the availability of robust velocity models that are typically derived from the analysis of the propagation of seismic waves. Velocity inversion in complex geology is ill-posed showing strong dependency on noise in the data, non-uniqueness and lack of sensitivity. Additional geophysical methods, such as high resolution time or frequency domain electromagnetics (TEM/CSEM), provide added sensitivity to geologic features. More unique results and decreased dependency on noise in the data can then be obtained by the joint use of multiple geophysical methods during the inversion. Various aspects are involved in this analytic integration process involving an appropriate choice of algorithms and workflows that are often problem-dependent.
