Deep IP – Distributed Array IP – 3D DCIP

DIAS32 is Dias Geophysical’s DCIP survey system that provides full, high quality, and high-resolution 3D resistivity and induced polarization models of the subsurface. The system uses modern proprietary technology that has significantly reduced the size and weight of the system and has increased the survey flexibility and scalability immensely. The DIAS32 is the most reliable surveying tool for every electrical target in every terrain challenge.

With integrated safety systems, DIAS32 is the leading IP Resistivity technology in survey safety. The receivers are also programmed with cable-free mesh networking capability, which seamlessly facilitates safety and real-time quality control during data acquisition.

All surveys are planned using optimization software for to determine the most efficient and effective results. No matter the target or site restrictions, the DIAS32 will optimize the best solution.

Leading-Edge 3D IP and Resistivity Imaging

Many aspects of the DIAS32 put the system at the leading-edge of 3D IP and Resistivity imaging.

  • Survey qualification and optimization
    • Selection and qualification of appropriate method through forward modelling
    • Optimization of survey parameters and specifications with proprietary software
  • Survey acquisition
    • Proprietary safety, acquisition, and processing technologies
    • Safe and efficient acquisition of low-noise, high-volume data sets
    • Calibration, sensitivity, and data-rich surveys enhance accuracy of the final models
  • Imaging
    • Initial 2D and 3D resistivity models using inversion
    • From voids to massive sulphides, and aquifers to shale

DIAS32 Advantages

  • Proprietary safety procedures and purpose-build technologies ensure a safer working environment for our field teams.
    • The DIAS-CL Current Lockout system enhances safety around high voltage operations.
    • The DIAS-LS Lightning Shunt technology mitigates risks due to lightning.
  • Optimized automation and survey methodology improves and streamlines field operations.
  • Mesh networking technology provides real-time monitoring of system health and data quality, meaning that any troubleshooting requirements can be addressed immediately in the field.
  • Injection Point Monitoring (IPM) of the current waveform and time-series recording drives the data accuracy and sensitivity, which further enhances confidence in the final resistivity imaging.
  • Proprietary signal processing routines produce low-noise final data.
  • The fully distributed array architecture allows for full flexibility in the survey design and survey implementation, and makes the system scalable.

Safety Advantages

  • Dias Geophysical adheres to industry best practices in the planning and execution of all surveys. These practices and procedures are contained in our HSE manual.
  • Dias has developed proprietary safety technologies that are integrates with the DIAS32 system. These technologies are detailed in our Safety Technologies page.
  • Our proprietary common voltage reference (CVR) mode of surveying has a significant impact on safety by reducing the overall exposure of our crews during surveying – less weight leads to less walking, which leads to less risk of injury.
  • The wireless mesh network technology that is integrated into our system receivers facilitates the immediate detection and precise location of any issues that may arise during the normal course of surveying, which inherently improves safety for our crews.
  • Dias manages all HSE matters through cloud software. From the field to the office to the warehouse, all documentation, training, tracking, and reporting is managed by this highly interactive and easy to use internet-assisted portal.

Operational Advantages

  • Each receiver is a single-channel recorder, meaning there are no restrictions for array layout. We place one DIAS32 recorder at each electrode station, so the DIAS32 system can complete any survey method or array with great efficiency.
  • The CVR mode of surveying allows for unparalleled flexibility in survey design and implementation. Where ground access is restricted due to land ownership or topography, the survey can easily be designed to avoid these regions.
  • The CVR method also facilitates waterway crossings. Because there are no move-ups as with conventional surveys, the crew only needs to cross the waterway once to lay out the array and once again to pick it up.
  • Because a DIAS32 recorder is placed at each receiver electrode, the GPS in the recorder accurately locates the electrode. This feature also allows for operational flexibility where a planned electrode location cannot be easily accessed due to safety concerns or other restrictions.
  • Energy management in the DIAS32 system is designed to allow the recorders to operate for several days before they need to be re-charged.
  • For DIAS32 surveys, traditional line-cutting is not required. In project areas where the vegetation is too dense to pass, the lines need to be brushed out, but no picketing or flagging is required.
