Overview

NORSAR-2D applies seismic ray theory to two-dimensional geological models. Geoscientists use it to understand how seismic energy travels through the subsurface and how that behaviour shapes recorded data.

By working in 2D, teams can test interpretations and acquisition scenarios quickly before committing to more complex workflows.

Key capabilities

2D seismic ray tracing
Time-to-depth conversion
Survey planning and evaluation
Seismic illumination studies
Synthetic seismogram generation
Ray path and seismic event analysis

Applications

Survey evaluation: compare acquisition layouts along a profile and assess how well target horizons are illuminated.

Interpretation support: trace ray paths and identify seismic events to verify interpretations and convert between time and depth.

Modeling studies: generate synthetic seismograms from geological models to compare with recorded data.
