What’s New in RadExPro 2025.4 (Major Improvements)

RadExPro 2025.4 focuses on real processing priorities: faster migration, cleaner stacking control, better event picking, enhanced QC tools, and productivity upgrades for large workflows.

1) Faster 2D Kirchhoff Depth Migration (major performance upgrade)

The 2D Kirchhoff Depth Migration module continues to evolve in 2025.4, and this release brings one of the most important improvements: faster travel-time computation. This helps reduce cycle time for depth imaging, especially when running multiple scenarios (different velocities, parameters, grids, apertures, etc.).

• Parallelized travel time computation for faster processing
• Option to compute travel times using a decimated grid (extra speed for large runs)
• Support to precompute multiple travel time versions and choose the required dataset during migration
• Travel time parameters now load automatically from the dataset and are auto-updated when selecting a travel time dataset

Why it matters: For many teams, depth migration is one of the most time-consuming steps in processing. Faster travel-time computation directly improves throughput and makes it easier to iterate toward cleaner images.

2) Ensemble Stack upgrades (more control over trace header operations)

The Ensemble Stack module in RadExPro 2025.4 gains improved control over how trace headers are handled inside ensembles. This is especially useful in real data where different header attributes or grouping logic need different treatments during stacking.

• Supports different operations for different trace headers within an ensemble
• Helps refine stacking strategies and supports better QC and repeatability

3) First Break Picking improvements (Global method enhancement)

RadExPro 2025.4 improves the First Break Picking workflow by adding a practical control to the Global method, helping pickers handle datasets where the first event might not always equal the strongest global maximum.

• New parameter: Maximum / Global Maximum ratio [%]
• If set below 100%, the picker can search for the first minimum/maximum event where the amplitude exceeds the selected threshold of the global maximum

Use case: Helpful for noisy spreads or mixed acquisition conditions where consistent picks require smarter thresholds instead of “always the biggest peak.”

4) Trace Math: new “Divide by Scalar” operation

RadExPro 2025.4 expands the Trace Math toolkit, adding another operation that supports everyday amplitude and normalization tasks.

• Divide by Scalar (Trace/Scalar operation)

5) Screen Display: FK Spectrum polygon export (better QC workflows)

For QC workflows that rely on FK analysis (noise isolation, filter design validation, documentation of processing decisions), RadExPro 2025.4 adds a useful capability in Screen Display.

• In the FK Spectrum window: Save Active Polygon command

6) Data Filter: start reading from a selected line (skip file headers)

Import and filtering tasks become easier with a small but important improvement:

• Starting line parameter when reading from a file
• Quickly skip file headers and begin reading clean numeric blocks (less manual prep)

7) Boulder Detection 2D/3D: additional output attribute

The Boulder Detection 3D/2D modules now store more useful information for interpretation and reporting:

• New output: Maximum attribute value within each boulder
• Saved as a separate column in the output ASCII table

8) License status bar: validity period display

For teams using time-limited licenses, RadExPro 2025.4 improves visibility and planning:

• License validity period is now shown in the status bar

Workflow Improvements (Modernized module parameters)

RadExPro continues migrating modules to a universal parameter style that improves usability and repeatability—especially for teams that maintain standard processing templates.

• Full replicas support (better repeatable workflows)
• Standard export/import of module parameters (faster project reuse)

Modules updated in RadExPro 2025.4:

• 3C Orientation
• Ensemble Equalization

Bug Fixes & Stability Improvements (RadExPro 2025.4)

RadExPro 2025.4 includes important fixes across processing and display workflows—reducing crashes and removing incorrect behavior introduced in earlier releases.

• Wavefield Subtraction: fixed crash when horizons cross or fall out of trace limits
• Trace Header Math: fixed frame_max() / frame_min() not working since 2025.1
• Synchronized Screen Displays: fixed issue where all displays could close together when exiting the last frame
• 2D Kirchhoff Depth Migration: fixed error when travel time dataset path is edited manually
• Travel Time Tomography: fixed incorrect topography processing
• Zero-Offset Demultiple: fixed crash when horizons fall out of trace limits

Why this matters: In production environments, stability improvements reduce lost time and help teams run long processing sequences with higher confidence.
