GeoTeric 2017.2.2 – Turbo charge your Interpretation
The bulk of the work in the patch is around interactivity performance which can be split into 3 sections:
- Horizon rendering performance
- Performance when data mapping large surfaces is much better
- Performance when shifting data mapped horizons is much better
- Users are no longer limited by the number of Horizon Points as before and should not need to reduce the number of horizon points in order to visualise the surface
- In previous versions, some horizons when mapped with data, turned ‘pink/red’ – this has been resolved and should no longer happen.
- Expression tools performance
- Noise & Fault Expression is between x2-x25 faster depending on setup.
- Spectral Expression is on average twice as fast.
- The best improvement will be seen in the ‘least optimal’ setup e.g. processing a large volume where the ‘data’ required for processing in the Expression tool doesn’t fit into the processing memory and project is accessed across a poor network or to an external USB disk.
- The least amount of improvement will be seen where the starting conditions were good e.g. local project using a small volume.
- Overall we have reduced the difference in performance seen when running the Expression tools on a project stored locally vs on the network, as well as the differences seen when temp file location being local vs network location.
- The results seen will vary greatly depending on a variety of factors, incl. volume size vs processing memory settings (GeoTeric option), shape of volume i.e. number of traces, physical location of GeoTeric project, network connectivity, location of temp file directory, RAID setup
- General interactivity performance:
- Changes to the code have halved the start-up time for GeoTeric.
- General interactivity has been improved. This will be particularly noticeable when adding and removing items to the scene - including slices, volumes, arbitrary lines, colour blends and data mapped horizons. Another area of improvement is when switching to data mapped mode for horizon and fault surfaces.
- Improvements will also be seen when panning through data using slices, arbitrary lines or volumes where the data should reach higher resolution quicker and the scene remain interactive throughout.
Other enhancements/bugs fixed in this patch:
- The waveform tracker (fill) in Adaptive Horizons now has improved snapping to peak / trough
- The histogram will now correctly zoom in when adjusting the colour bar compression
- Support for NVIDIA Pascal cards on Linux
- We have fixed an issue where Horizon interpretation occasionally crashed with a well in the 3D scene.
- We have fixed a crash caused by exporting a GeoImage in the Linux version.
- The Dip attribute returned an invalid number in certain floating point volumes, which in turn caused Fault Expression to fail. This has been resolved.
- Fault Expression: Detect on CMY now always returns a result.
- In the batch processor sometimes you weren’t able to edit name of output volume. This has been resolved.
- Transferring data following fault sticks to DSG using the Link crashed DSG. This has been resolved.
- Fixed an issue where the STOIIP calculator sometimes showed wrong units.
