SibER - multi-electrode resistivity surveying set

Landviser, LLC is offering advanced equipment for deep electrical tomography - Siber-48 - manufactured by KB Electrometry, Ltd in Novosibirsk, Russia. Since 2012 they started to produce modificated version of "SibER". New device has new safer body, powerfull generator (inject current up to 2A), provide more stable and faster measurments.

Price of the system ordered through us is the same as listed on Registered users can view complete price of the SibER-48 and SibER-64 equipped with two standard 5-m spaced cables in current catalog. Custom spacing of electrode connectors on the cables is also available per request.

Please, request your personalized quotation from us: or call 1-609-412-0555 / 1-888-306-LAND. The system is shipped worldwide from Russia, shipping costs will vary. See specification table at the bottom of this page on estimated weight of the system and components.

pseudosection for 2D resistivity surveys

Example of electrodes arrangement and measurement sequence that can be used for a 2-D electrical imaging survey is shown on the left. Many different multi-electrode systems have been developed over the past 15 years using different arrangements of the cables and measurement strategies (Loke, 2011). This program is designed to invert large data sets (with about 200 to 100000 data points) collected with a system with a large number of electrodes (about 25 to 16000 electrodes). The survey is usually carried out with a system where the electrodes are arranged along a line with a constant spacing between adjacent electrodes. However, the program can also handle data sets with a non-uniform electrode spacing. RES2DINV program can be used for surveys using the Wenner, pole-pole, dipole-dipole, pole-dipole, Wenner-Schlumberger, gradient and equatorial dipole-dipole (rectangular) arrays. In addition to these common arrays, the program even supports non-conventional arrays with an almost unlimited number of possible electrode configurations (Loke et al. 2010). You can process pseudo sections with up to 16000 electrode positions and 70000 data points at a single time on a computer with 4 gigabytes (GB) of RAM. Besides normal surveys carried out with the electrodes on the ground surface, the program also supports aquatic and cross-borehole surveys.

Supports the Wenner (alpha,beta,gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, gradient and non-conventional arrays. 
Supports exact and approximate least-squares optimisation methods 
Supports smooth and sharp constrasts inversions 
Supports up to 16000 electrodes and 21000 data points on computers with 1GB RAM 
Seamless inversion of very long survey lines using sparse inversion techniques 
(RES2DINV only license includes limited used of RES3DINV 3D inversion program)

RES2DINV software is designed to interpolate and interpret field data of electrical geophysical prospecting (2D sounding) of electrical resistivity (conductivity) and induced polarization. The inversion of the resistivity and IP data is conducted by least-square method involving finite-element and finite-difference methods. The software can handle data from any electrode array, including Wenner (a, b, g), dipole-dipole, inline pole-dipole, pole-pole, Wenner-Schlumberger, equatorial pole-dipole and non-conventional arrays. Interpolate data from land, under water, and cross-borehole surveys. Easy data conversion from the most popular geophysical instruments including ABEM  Lund, Syskal, AGI, PASI, IRIS, SCITREX, etc.
