In areas where the geological structures are approximately two-dimensional (2D), conventional 2D electrical imaging surveys have been successfully used. Multi-core support with RES3DINVx32/圆4, 256GB memory support with RES3DINV圆4 Supports parallel calculations on Intel (and compatible) based computers Supports surveys with electrodes at arbitrary positions (RES3DINV圆4) Supports more than 20000 electrodes and 100000 data points on computers with 16GB RAM (RES3DINV圆4) Supports up to 5041 electrodes and 67500 data points on computers with 1GB RAM (RES3DINVx32) Now available as a combined package together with RES2DINVx32/圆4, the 2D Resistivity & IP inversion program. (a) Apparent resistivity pseudosection, (b) resistivity model section, (c) apparent metal factor pseudosection and (d) metal factor model section. The inversion of this data set, which has 67 electrode positions and 339 data points, takes seconds on a modern PC.įigure 2. and Barton, K, 1995, Seeing beneath Rathcroghan. This survey was carried out across a circular mound which is thought to contain some important Irish archaeological burial chambers (Waddell, J. The figure below shows an example from an electrical imaging survey in an area with fairly complex subsurface geology and significant surface topography. Chemical Engineering Journal, 77, 11-18.) is used for IP data inversion. Complex resistivity tomography for environmental applications.
The complex resistivity method (Kenma, A., Binley, A., Ramirez, A. Resistivity information from borehole and other sources can also be included to constrain the inversion process. A robust data inversion option is also available to reduce the effect of noisy data points. Two different variations of the smoothness constrained least-squares method are provided one optimised for areas where the subsurface resistivity varies in a smooth manner (such as chemical plumes), and another optimised for areas with sharp boundaries (such as massive ore bodies). The smoothing filter can be adjusted to emphasize resistivity variations in the vertical or horizontal directions. However, the parameters which affects the inversion process can be modified by the user. The program will automatically choose the optimum inversion parameters for a particular data set.

Together with the free 2D forward modeling program RES2DMOD, it forms a complete 2D resistivity forward modeling and inversion package. Four different techniques for topographic modelling are available in this program. On a modern microcomputer, the inversion of a single pseudosection is usually completed within seconds to minutes. The use of available memory is optimised so as to reduce the computer time by minimising disk swapping. This program has been optimised for the inversion of large data sets. It is completely automatic and the user does not even have to supply a starting model. The RES2DINVx32/圆4 programs use the smoothness-constrained Gauss-Newton least-squares method inversion technique to produce a 2D model of the subsurface from the apparent resistivity data alone. The results from such surveys are usually plotted in the form of a pseudosection (Figure 1a) which gives an approximate but distorted picture of the subsurface geology. Two-dimensional (2D) electrical imaging surveys are now widely used to map areas of moderately complex geology where conventional 1D resistivity sounding and profiling techniques are inadequate.
