GRS specialise in the acquisition, processing and interpretation of high quality ground electrical geophysics through the MIMDAS system. With true 3D capability, real time QC and telluric cancellation through time synchronised remote MT acquisition GRS truly are the industry leaders in IP/RES/MT.
​
Since 2014 GRS has been using MARE2DEM code to invert joint MT/CSEM data. This advanced signal processing is allowable when collecting both transmit current and received signal voltages at high sample rates - as is standard with MIMDAS.
​
​
This enables the joint inversion to be applied to historic datasets as has been done at Olympic Dam, Prominent Hill and Carrapateena.
​
Results include more accurate resistivity models rather than using DC alone, greater depth extent and increased structural information.
MIMDAS
Run privately since 2003 MIMDAS offers a complete package in electrical geophysics. Using a distributed array channels are almost limitless with true 3D acquisition possible. Any array type using any transmitter combined with great signal to noise receivers and cutting edge processing and modelling makes MIMDAS the industry leader in IP/RES/MT acquisition.
Magnetotellurics
AVAILABLE NOW!
2-5 component standalone MT receivers for regional acquisitions
​
Newly developed three channel receivers wirelessly connected to controlling software. The new "Vegas" boxes are a versatile regional and project scale acquisition option. Signal to noise only comparable to MIMDAS expect the highest quality in geophysical MT surveying.
Magnetics
Ground magnetics has been a commonly used technique in mining exploration for decades. More recently the this method has been applied to the coal industry where it has the potential to map potentially problematic igneous rock formations within coal sequences. This pre-screening allows potential savings in follow-up drilling programs.
