Abstract:Different geophysical data reflect rock properties from different aspects,and joint utilization of such complemental information may better image subsurface geology.Electromagnetic prospecting and seismic prospecting are two ways of geophysical exploration with different mechanisms.Seismic prediction suffers from the issue of non-uniqueness,and electromagnetic prospecting may render useful information which is absent in seismic data.Thus,joint utilization of electromagnetic and seismic data can provide more credible support for exploration and development decision making.Joint electromagnetic-seismic inversion,as a method of quantitative interpretation,may mitigate the non-uniqueness of single-data inversion and improve the credibility of geophysical interpretation.We give an overview of the classification,progress,and opportunities of joint inversion in China and around the world,as well as its future development.
