adding value by delivering useful knowledge through innovation and resolve

Dias Geophysical is a ground geophysical service provider that specializes in delivering 3D and 2D resistivity and induced polarization survey solutions worldwide. Dias has developed its proprietary DIAS32 survey technology to deliver a new level of survey performance and model accuracy.

Safely ahead of the rest – With rigorous safety procedures and integrated safety systems such as our proprietary lightning shunt and current lockout technologies, Dias is leading the industry forward on survey safety.

Flexible and scalable – The DIAS32 system’s fully-distributed architecture facilitates maximum flexibility in survey design, and CVR acquisition, which allows for full scalability.

Depth sensitivity and data richness – The DIAS32 mode of surveying delivers a multi-scale data set (many different dipole sizes are acquired simultaneously) which significantly enhances depth sensitivity, and in 3D mode, the system delivers multi-azimuth dipoles. The combination of multi-scale and multi-azimuth data provides a rich data set which improves the accuracy and resolution of final 3D models.

The cable-free mesh networking which forms the core of the DIAS32 system facilitates real-time quality control, data capture, and system health monitoring, and provides a wide variety of safety and operational benefits.

In addition, the DIAS32 system acquires time series data, and we actively monitor for leaks in the current transmission lines.
