Regional 2D Line Merging for NDR

Use Case

Creating Basin-Wide, Aligned, Merged 2D Seismic Layers

Business Challenge

Merging large 2D seismic datasets across basins is challenging due to varying coordinate systems, vintages, and inconsistent quality. These fragmented datasets hinder regional mapping, regulatory submissions, and collaboration.

Inconsistent coordinate systems and projections, making alignment across basins error-prone and unreliable.
Overlapping and intersecting seismic lines, often undocumented, cause spatial conflicts in interpretation.
Velocity model mismatches, leading to inconsistencies in depth conversion and stratigraphic correlation.
Delays in regulatory readiness, with prolonged QC cycles before data can be ingested into NDR platforms.

The AI Approach

To tackle fragmentation across multiple vintages and basins, the client adopted an AI-powered seismic merging workflow to align, harmonize, and consolidate 2D seismic data into a unified, regionally consistent layer.

AI-based line overlap detection and alignment logic was used to identify spatial intersections and rectify mismatches across adjacent 2D lines.
Coordinate system harmonization was achieved using EPSG re-projections and datum transformations to unify geospatial references across surveys.
Merged velocity model construction blended data from multiple vintages using regression fitting and structural ties to ensure consistent depth references.
Final output consolidation delivered merged SEG-Y files, shapefiles, and velocity overlays optimized for interpretation platforms and regulatory systems.
