Geophysics data and imagery processing

Oasis Montaj, developed by Geosoft Inc, Canada. This software is used to perform data reduction, geophysical image processing, 3D visualisation and final map edition.

Induced polarization and resistivity interpretation and modeling software

RECONSULT understands that the key to interpreting induced polarization (IP) and resistivity (RES) is the integration of these data with other indirect information such as airborne geophysics, geochemistry results and superficial geology data. RECONSULT uses the TS2DIP software by Zonge to model IP and RES information. The resultant models are integrated with other sources of information in plan and section views. When the IP and RES data are acquired in a regular grid, the inversion results are interpolated in a tridimensional way through voxels to perform 3D integration, especially when there are historical drillholes that may have not tested the detected polarisable bodies correctly.

Gravity and magnetic interpretation and modeling software

RECONSULT uses the Oasis Montaj from Geosoft Inc as its platform to process gravity and magnetic images. In this software, special transformed field images are elaborated such as low latitude reduced to the pole filter and the fractional derivative ternary distribution, aiming at creating a plan view interpretation that highlights all the geological information that is presented in the geophysical datasets. To estimate the spatial positioning (mainly the depth) and the geometry of the magnetic and/or dense sources RECONSULT uses the ModelVision Pro and UBC-GIF software that were developed in Australia and Canada, respectively. Both programs invert 3D data using different mathematical approaches. The ModelVision uses prismatic bodies with constant physical properties that differ them from the background. The UBC works with tridimensional meshes that are associated to a specific physical property for each voxel making it possible to have changes in the physical properties of an anomalous body.

Electromagnetic interpretation and modeling software

Based on the same concepts that underlie magnetic and gravity guide interpretation, RECONSULT has been investing in implementing world class services in electromagnetic (EM) interpretation over the past ten years. Currently, RECONSULT meets an old demand of the Brazilian mineral exploration industry, the lack of EM specialists. RECONSULT became a reference in using the Maxwell software that inverts EM data, mainly in time domain, acquired in holes (borehole EM technical), over the surface and in airborne systems, such as the VTEM and the HeliGEOTEM, both in moving wing platform. Some of RECONSULT’s achievements in EM interpretation are described in academic papers that report cases of sulphide rich and conductive bodies in depths frequently bellow 100 metres that were successfully intercepted after the company conducted inversion processes using Maxwell.


RECONSULT has operated and operates the following American pieces of equipment to perform gravity surveys: Lacoste Romberg, Scintrex CG-3 or Scintrex CG-5. The company will choose the one that best suits the specifications of the survey and the client’s needs, offering the best cost vs. benefit ratio.

GSM-19 magnetometers

Made by TerraPus from Canada. A set of base and rover magnetometers and sensors. The rover unit has a built in GPS that enables the performance of surveys that don’t require cutting and pegging line. This type of magnetometer is suitable for areas located near the magnetic equator, where the magnetic field is horizontal and weak. Brazil has many areas that fit this profile in its northern region.

Susceptibilimetres and condutivimeter MPP-EM2S+

Manufactured by the Canadian company GDD Instrumentation. Devices used to measure conductive and magnetic susceptibility of rock samples and drillhole cores digitally and simultaneously.
