The Interpretation bar provides tools for seismic horizon and fault interpretation, including automatic picking, correlation control, AI-assisted detection, and import/export of interpretation objects.

The bar consists of the following groups: Picking, Horizons, Horizons Management, AI Faults Detection and Faults Management. For more information about the supported formats refer to Horizon Data Formats and Fault Data Formats.

This bar brings together the horizon and fault interpretation tools that were previously divided between separate bars, so that picking, horizon map updates and the import and export of both horizons and faults are all available in one place. External topography is no longer loaded from this bar — it is now loaded from the Topography item in the Data Manager context menu.

Picking

Defines how horizons are picked in the seismic views. The available parameters are:

• Pick mode — the picking mode (for example Autopicking).
• Pick type — the trace feature picked, such as Zero phase, peak, or trough.
• Magnet type — how the pick snaps to the seismic signal (for example Cross-correlation).
• Picking window and XCorr window (ms) — the time windows used for picking and for cross-correlation.
• XCorr threshold (%), XCorr with, Radius limit and Override in radius — control the correlation quality, the reference seed, and the radius within which picks are accepted.

These picking parameters are set directly in the bar and are also available in Module Properties.

A full description of the picking workflow is given in Seismic picking.

Horizons

Update the selected horizon maps from the current horizon picks.

Run the AI Horizons Stack wizard to automatically pick several horizons across the seismic volume using a trained model. To add the current settings to the active workflow without starting the calculation, select Save to workflow. When you open the saved job from the workflow, the wizard restores its settings; after editing them, select Save to update the job. See Workflows for instructions.

The wizard calculates in five steps, each on its own tab: select Calculate on a tab to run that step alone, or Calculate All to run the whole sequence. While a step runs, the progress bar at the bottom of the wizard identifies it — for example Step 1 of 5: Fault + Flattened — and the detailed progress of the running calculation is shown in the main window.

On the Fault + Flattened tab, set Start time and End time before selecting Calculate All. The selected range also limits Ridge, Dip and RGT results and generated horizons on each trace; no results are calculated outside it. The Horizons tab inherits this range when its Use options for Start Time and End Time are cleared. Enable either option to narrow horizon extraction further. To process the full trace, leave both initial selectors at Entire gather and the Horizons limits cleared.

Generated horizons follow the live-trace coverage of the selected source seismic volume. On inline and crossline sections, the empty regions beyond that coverage contain no generated horizon points or line segments.

Select Stop to end the step that is running; the button is active only while a calculation is in progress. g-Space then reports that the step was stopped instead of reporting a failure and keeps the outputs already produced in the project. If the run was started with Calculate All, the remaining steps are not started.

Horizons Management

Import and export horizon interpretation data. For more information refer to Import horizons / Export horizons.

Save horizon binary

Import horizon ASCII

Import horizon (charisma format)

Export current horizon ASCII

AI Faults Detection

Runs AI-assisted fault detection on the selected seismic data to automatically highlight fault surfaces. See AI faults wizard and Fault prediction for the full workflow.

Faults Management

Import and export fault interpretation data. For more information refer to Import faults / Export faults.

Export faults binary

Load faults binary — add faults from a binary file to the existing faults. If an imported fault name is already in use, g-Space appends _2, _3, and so on so that both faults are kept. If the file cannot be parsed, g-Space reports that it could not load the fault file and leaves the existing faults unchanged.
