DIAS32 Resistivity/IP System

DIAS32 Resistivity/IP System

Deep IP  –  Distributed Array IP  –  3D IP and Resistivity

DIAS32 – leading-edge 3D resistivity imaging

  • Survey qualification and optimization
    • selection and qualification of appropriate method through forward modeling
    • 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-built technologies assure 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 yields efficient and effective field operations.
  • mesh networking technology provides real-time monitoring of system health and data quality
  • injection point monitoring (IPM) of the current waveform and time series recording drive data accuracy and sensitivity to enhance 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 survey design and 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.
  • In addition, Dias has developed proprietary safety technologies that are integrated with the DIAS32 system. These technologies are detailed in our Safety Technologies page.
  • Our proprietary common voltage reference (CVR) mode of surveying also has a significant impact on safety by reducing the overall exposure of our crews during surveying – less weight, less walking.
  • The wireless mesh network that resides in all of our system receivers also improves safety for our crews. This network facilitates an immediate identification of, and precise location for, any issues that my arise during the normal course of surveying.
  • Dias manages all its 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, so there are no restrictions for array layout. We place a DIAS32 recorder at each receiver electrode, so the DIAS32 system can complete any survey method or array with great efficiency.
  • The CVR mode of surveying allows for great 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 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 linecutting is not required. Where the vegetation is too dense to pass, the lines will need to be brushed out, but no picketing or flagging is required.
