The Fault Prediction tool in g-Space helps identify and analyze fault structures in seismic data. Access this tool by pressing Alt + right-click on any seismic section.

Time Analysis Parameters

• Correlation time window: Defines the vertical analysis window for examining seismic trace patterns, measured in milliseconds. A larger window considers more data vertically.
• Correlation bin window: Determines how many adjacent bins (traces) to analyze horizontally. Larger values include more neighboring traces for pattern recognition.
• Maximum shift: Sets the maximum allowable time shift when correlating traces, measured in milliseconds. Limits the search range for matching patterns.

Visual Enhancement

• Time stretch: Controls the vertical exaggeration percentage of the display. Higher values enhance fault visibility by making them appear more vertical.

Smoothing Controls

• Sigma for local faults: Fine-tunes the smoothing for detailed fault features. Lower values maintain more local detail.
• Sigma for generalized faults: Controls regional fault trend smoothing. Higher values emphasize major fault systems.
• Sigma for noise reduction: Determines noise filtering intensity. Higher values produce cleaner images but may reduce subtle details.

Processing Control

• Autopicking step: Sets the increment between automatic fault picks. Lower values increase detail but require more processing time.

Saving Predictions

The right-click context menu on a time seismic section provides options to turn predictions into fault geometry:

• Run fault prediction - compute the fault prediction for the current section.
• Create new stick from prediction - build a single stick from the prediction at the clicked location.
• Create new sticks from all predictions - build sticks for every predicted fault on the section in one step and save them as free sticks (named PredictedStick_1, PredictedStick_2, and so on).
