Geotomo res2dinv software#

He is the Director (Software Development and Technical Support) of Geotomo Software Sdn Bhd. from the School of Earth Sciences, The University of Birmingham in 1994 under the supervision of Dr. M.H.Loke, the developer of the RES2DINV and RES3DINV software, obtained a P.hD. Support for mult-core CPUs is now available with RES3DINVРµСљвЂ 4.Р”Вr. On a modern quad-core based microcomputer, the data inversion takes less than a minute for small surveys with 200 electrodes in a flat area, to a day for extermely large surveys with with thousands of electrodes in rugged terrain. It now supports parallel calculations on multi-core CPUs that significantly reduces the inversion time for very large survey grids. In addition to surveys with a traditional rectangular grid of electrodes, it also supports surveys with trapezoidal grids and even arbitrary electrodes arrangements which is common in rugged and/or forested areas. It is probably more than an order of magnitude faster than some other commercially available 3D inversion software.

It supports surveys with up to about 10000 electrodes and 150000 data points. To reduce costs to the user, RES3DINV is sold as a combined package with RES2DINV which costs only about 25% more than the RES2DINV program alone. 3D surveys are more time-consuming and expensive to carry out, but could be useful for very complex geological situations. RES3DINV is the 3D resistivity and IP inversion software, and it is probably the first widely available commercial software of this type. Multicore CPU support is now available in RES2DINVРµСљвЂ 4. The program supports survey lines with up to 16000 electrodes and 27000 data points. In addition to the standard Wenner (alpha, beta, gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole arrays it also supports non-conventional electrode arrangements. Besides normal land surface surveys, it also supports underwater and cross-borehole surveys. RES2DINV is the 2D resistivity and IP inversion software.

Geotomo res2dinv update#

For current RES2DINV and RES3DINV users, you can update the software by just downloading the same files. The demo versions have some limitations, but you can use them to invert most common resistivity and IP data sets.

At this site, you can download working demo versions of the RES2DINV and RES3DINV inversion software. The second development that has made 2D and 3D electrical imaging surveys practical tools is fast interpretation software that can be used on commonly available Windows based microcomputers.

A set of free lecture notes (Spanish version aso available) which cover a number of practical aspects of 2D and 3D electrical imaging surveys, including field methodology and data interpretation, is available in the 'Downloads' page of this website. Over the last 20 years, there has been an explosive growth in the number of commercial multi-electrode resistivity meter systems for electrical imaging surveys sold by companies in Europe, North America and Asia. A recent development is 4-D time-lapse surveys. However due to recent developments in field equipment design, interpretation software and microcomputer technology, two-dimensional (2D) and three-dimensional (3D) surveys are now practical geophysical exploration tools for environmental, engineering and mineral exploration studies.

Until the early 1990's, the resistivity method has been used as a one-dimensional (1D) tool where quantitative modelling was confined to simple horizontal layers which are not sufficiently accurate for complex geological environments. Over the last 25 years, there has been a revolutionary change in the resistivity (and IP) surveying method.
