ABSTRACT: An innovative inversion code, named “Curupira v1.0”, has been developed using
Matlab to determine the vertical distribution of resistivity beneath the
subsoil. The program integrates Vertical Electrical Sounding (VES), successful
in shallow subsurface exploration and Time Domain Electromagnetic (TEM)
techniques, better suited for deeper exploration, both of which are widely
employed in geophysical exploration. These methodologies involve calculating
subsurface resistivity through appropriate inversion processes. To address the
ill-posed nature of inverse problems in geophysics, a joint inversion scheme
combining VES and TEM data has been incorporated into Curupira v1.0. The
software has been tested on both synthetic and real-world data, the latter of
which was acquired from the Parana sedimentary basin which we summarise here.
The results indicate that the joint inversion of VES and TEM techniques offers
improved recovery of simulated models and demonstrates significant potential
for hydrogeological studies.
