| Abstract: | One of the ways to improve the information content of a set of field data is that of combining the interpretation of disparate
data sets. Electromagnetic and direct current resistivity methods suffer from inherent equivalence problem. Application of
joint inversion for these measurements can overcome the problem of equivalence very well. In the present work, synthetic data
from vertical electrical sounding (VES) and horizontal coplanar low-frequency induction sounding (EMHD) are inverted individually
and jointly over different types of 1D earth structures. Global optimization with Monte Carlo Multistart algorithm was used
in the calculations. The results obtained from the inversions of synthetic data indicate that the joint inversion significantly
improves the solution reducing the ambiguity of the models. |
