Seismic Refraction Tomography (SRT)
Seismic Refraction Tomography (SRT)
Seismic Refraction Tomography (SRT) is an advanced seismic imaging technique used for detailed subsurface profiling, rock quality assessment, weathered zone identification, and geotechnical investigations.
SRT surveys provide accurate subsurface velocity models and geological stratification data for tunnels, dams, highways, mining, and infrastructure projects.
Daily Coverage Capacity
Survey Coverage: 1–5 Line KM/day
Key Deliverables
• Subsurface Layer Interpretation
• Seismic Velocity Tomograms
• Bedrock Depth Estimation
• 2D/3D Refraction Models
Accuracy & Data Quality
-
SRT provides enhanced accuracy and resolution compared to standard seismic refraction techniques.
- Detailed 2D velocity models of subsurface layers
- Improved detection of lateral variations and weak zones
- Higher reliability in complex geological conditions
- Accuracy depends on survey design, geophone spacing, and processing quality
