Property identification of anomalous seismic bodies by GMES techniques, a case history.

What are the anomalous seismic reflection bodies at depths of over 6000 m? Are they reefs or igneous rock? This is a difficult problem for seismic techniques, but the GMES technique can handle it. The GMES technique is a joint exploration technique combining gravity, magnetic, electrical, and seismic techniques. The specific procedure is to conduct a 2D interface-constrained CEMP inversion using 2D seismic and log data followed by a property parameter inversion of the anomalous bodies using gravity and seismic data by the stripping technique. We then estimate the physical properties of the anomalous bodies, such as density, susceptibility, resistivity, velocity, and etc. to deduce the geological features of the bodies and provide a basis for drilling decisions. The work in the TZ area reported in this paper shows the applicability of the technique. [ABSTRACT FROM AUTHOR]
