In areas where geological structures are approximately bi-dimensional (2D), standard 2D electrical surveys have been successfully used. Main limit of that surveys is probably the assumption of a 2D structure. In areas with remote structures, the only effective solution is a completely 3D survey. Supported arrays include pole-pole, pole-dipole, dipole-dipole, equatorial dipole-dipole and Wenner-Schlumberger, together with non-conventional arrays. The RES3DINVx32/x64 programs use smoothness-constrain ed Gauss-Newton least-squares inversion technique to produce a 3D model of the subsurface from apparent resistivity data alone. Like RES2DINV, it is completely automatic and user does not even have to supply a starting model. A Intel multi-core (or compatible CPU) based computer with at least 2 GB RAM and an 500 gigabyte hard-disk is recommended. It supports parallel calculations that significantly reduce inversion time. RES 3D Professional can access up to 192 GB RAM; it can support 3D time-lapse inversion and also non-rectangular survey layouts (including inclined boreholes) using arbitrary electrodes data format, and I.P. inversion through complex resistivity method.
