View upcoming changes on the Roadmap

The latest installers can be found on the downloads page.

Intrepid 6.1.5 brings a raft of new updates including a extensive reworking to 3D visualisation to target performance using shaders, image exporting and the addition of the superquadric glyph. The release of the 2020 National TMI Grid for Australia created by Intrepid Geophysics’ Mike Morse for Geoscience Australia leveraging these new capabilities.
Intrepid 6.1.5 is available upon request as part of the open beta.

Intrepid v6.1.5

Intrepid Open Beta Testing

Internal and closed beta testing of the upcoming Intrepid 6.1.5 release has been ongoing for several months. We would now like to extend an invitation to all current Intrepid users to the open beta testing phase. Testing and providing feedback greatly helps us improve the software.

Version 6.1.5 carries numerous changes to the user interface, performance improvements and stability upgrades. The beta will be available on both Windows and Linux and is available upon request.

Updated Intrepid Tools: 3D Explore, Isostatic Gravity Correction, Multi-scale edge detection wizard, Intelligent Search (Batch) and the Gravity Import Wizard.

Two new tools, TrendQ Gridding and Dataset Rarification are now available.

3D Explore has seen the inclusion of custom shader code to optimize mixing geophysics signals without loss of resolution and to assist in handling large datasets.

To report your feedback/issues please submit a ticket to our support team. If you discover a bug or regression, please include a list of steps taken in your ticket so that we can try to reproduce it (Intrepid Support).

TrendQ Gridding

The new trend gridding tool has started to be rolled out as a service option for customers as part of our geophysical data processing. Trend gridding is a powerful tool to uncover trends in your data that might otherwise be hidden due to the flight line direction. The TrendQ Gridded Product demonstrates the enhancements in quality and interpretability of the trended grid. This applies when there are 2D bodies causing the gridded signal to show Boundinage style manifestations, when the underlying geology is more uniform in thickness. These features, which are visible as circular anomalies in standard gridding process, easily mislead interpretations and can be avoided by using the TrendQ process.

Intrepid, AEM and AWS

Intrepid Geophysics has recently collaborated with Amazon Web Services to bring our AEM Inversion service to the cloud. 2.5D Airborne Electromagnetic inversions are now able to be run on AWS, allowing for rapid scaling in projects and faster turnaround for larger scale surveys.

Services and Expertise

Throughout the year Intrepid Geophysics has been routinely producing regional and permit scale results for global clients. Alongside our current services, the Intrepid Geophysics team have been adding further AEM products:

  • Joint Induced Polarization and Superparamagnetism (IP and SPM) Inversion
  • Joint Inversions with starting 2d/3d geolectrical model
  • Joint Inversions with guide/reference geoelectrical model

As well as Geological and Geophysical Products:

  • Isostatic Corrections (collaboration with Richard Lane)
  • 4th order derivative model for noise to data convergence
  • Geophysical drone data acquisition design and quality control workflow including pitch and roll corrections.
  • Multi Scale Edge Detection to influence or quality control current geological models
An Upcoming Venture

A new product is being engineered to slot into the geology/geophysics integration space. This builds on our collective experience in the industry of 35 years, and makes use of the latest compilers, toolkits, and templating.

This new product aims to achieve the systematic characterization of geological uncertainty, informed by geophysics. With the capability for visualize complex 3D Datasets and reduce to a common earth model, on desktop and cloud.

Superquadric Glyphs in 3D Explore - Providing Intuitive Visualisation of Vector, Tensor and Time Domain Measurement Data

As geophysical observations become more complex, involving phenomena like gradients and time decay curves, we can begin to see that our limited and standard imaging options available do not convey the complexity. Intrepid has begun using glyphs and the advances made in the modern graphics card to address these issues and provide intuitive visualisation of complex systems.

The latest addition to this effort is the superquadric tensor glyphs, as described by Kindlmann the superquadric provides a balance between the symmetry of ellipsoids, and shape and direction of cylinders and cuboids for the visualisation of tensor data.

Software and Expertise In Motion

Intrepid Geophysics is pleased to announce our recent collaboration with Sihayo Gold Limited to assist with their exploration of the complex geology around the Sumatra fold belt, searching for Gold-Copper deposits. Leveraging off the previously collected magnetics, radiometrics and gravity data, Intrepid Geophysics is well placed to assist Sihayo Gold’s exploration efforts with our world leading geophysics processing software. A sample of the work done will be presented in a paper at European Association of Geoscientists and Engineers conference titled: Role of advanced geophysical processing in searching for the next giant Gold-Copper deposit in North Sumatra.

Incoming changes for 6.1.5

The traditional web-based technology used in JetStream is now upgraded, using the Google microservices and messaging, and the JetStream Service’s functionality has been extended in the Intrepid Project Manager. The JetStream catalog is also made more flexible, by being upgraded to the internal ioDB standard. Hence many more fields are “standard”, as are the set of tools to build and support the catalog.

Multi-scale edge detection wizard has been updated to enable all batch functionality including the loading and saving of task files.

GridMerge now supports 64bit indexing, which enables the tool to track the grid-refinements and processing for 32+ gigabyte output grids.
