AGS Res2DInv 5.0: Advanced 2D Resistivity and IP Inversion Software

Discover the cutting-edge features of AGS Res2DInv 5.0, a premier tool from Aarhus GeoSoftware (AGS) for processing and inverting 2D electrical resistivity tomography (ERT) and induced polarization (IP) data. Integrated into the Seequent ecosystem, this version revolutionizes geophysical workflows for groundwater exploration, environmental monitoring, geotechnical assessments, and mineral prospecting. With lightning-fast inversions and intuitive tools, Res2DInv 5.0 transforms raw survey data into actionable subsurface models, supporting arrays like Wenner, Schlumberger, and dipole-dipole for precise imaging of geological structures.

Key New Features in Res2DInv 5.0

AGS Res2DInv 5.0 overhauls the user experience with a redesigned interface, enhanced processing, and visualization tools that slash iteration times and boost accuracy in resistivity inversion. Released in 2023 with point updates like 5.0.2 for stability, it eliminates tedious data cleaning cycles while maintaining compatibility with legacy formats.

  • Redesigned Tab-Based Interface: Streamlined workflow for seamless data processing, inversion setup, and result evaluation. Evaluate processing impacts on measured data effortlessly, re-process datasets, and create new models without disrupting your flow.
  • Customizable Inversion Settings and Direct Data Editing: Tailor inversion parameters on-the-fly and edit data points directly from pseudosections or profiles. Link electrodes to data for quick identification and correction of issues, ideal for handling noisy field data in ERT surveys.
  • Lightning-Fast Inversion Engine: Achieve rapid 2D inversions with real-time model grid previews. Visualize changes to grids instantly during setup, accelerating iterations for large datasets from multi-channel instruments.
  • Enhanced Visualization Options: Right-click for instant access to high-impact presentations, including live pseudosection updates and 2D time-lapse capabilities. Compare multiple survey results side-by-side for temporal monitoring in environmental or hydrological studies.
  • Simplified Licensing with Seequent ID: Subscription-based system for easy administration—assign licenses organization-wide via MySeequent. Trade-in options available for legacy dongle users under maintenance contracts.

These innovations make Res2DInv 5.0 indispensable for geophysicists seeking efficiency without sacrificing depth in subsurface analysis.

Core Modules and Capabilities

AGS Res2DInv 5.0 focuses on robust 2D inversion, with seamless integration to Res3DInv for 3D extensions. It handles diverse input formats (e.g., .dat for Wenner arrays, equatorial dipole-dipole) and outputs models in formats compatible with Seequent’s Leapfrog for 3D visualization.

Data Processing and Inversion

  • Automated Data Import and Filtering: Support for aquatic, land, and cross-borehole surveys (legacy in 5.0). Robust noise filtering and outlier detection for clean datasets.
  • Array Type Flexibility: Optimized for common configurations like Wenner-Schlumberger, with gradient and pole-dipole support.
  • IP Effect Modeling: Joint inversion of resistivity and IP data for enhanced resolution of chargeable structures.

Model Building and Analysis

  • Finite-Element Forward Modeling: Smooth or robust inversions with damping for sharp boundaries, incorporating topography.
  • Time-Lapse Inversion: Monitor changes over time for applications like leak detection or contaminant plume tracking.
  • Uncertainty Estimation: L2/L1 norm options and sensitivity analysis to quantify model reliability.
