Abstract
Driven by needs in the Mineral exploration market for ever faster and ever easier setup of large 3D resistivity and induced polarization, autonomous and cable-less recorded systems come to the forefront. Opposite to the traditional centralized acquisition, this new system permits a complete random distribution of receivers on the survey area allowing to obtain a real 3D imaging.
Nevertheless, thanks to their geographical configuration, these new systems can record negative apparent resistivity and chargeability which could disappoint users.
Up to now, state of the art processing does not take into account negative values for inversion. That means new instruments bring in that context new opportunity for processing development.
