Geophysical Survey Package

Non-invasive pre-drilling reconnaissance and optimization

Package Overview

The Geophysical Survey Package combines seismic profiling and electrical resistivity surveys to provide a comprehensive, non-invasive subsurface model before any drilling occurs. This precursor approach optimizes the overall investigation strategy and significantly reduces unnecessary drilling costs.

What's Included in the Package

• Site assessment and survey design
• 2D Seismic profiling surveys
• Seismic data acquisition and processing
• 2D Electrical resistivity tomography (ERT) surveys
• Multi-electrode data acquisition
• Resistivity inversion and modeling
• Integrated data interpretation
• Subsurface geological model development
• Optimal borehole location recommendations
• Survey report with maps and profiles

Best For

• Large project sites (infrastructure, industrial)
• Pre-drilling reconnaissance and planning
• Groundwater exploration and source identification
• Quarry and excavation site evaluation
• Contamination assessment and mapping
• Complex geology requiring detailed mapping
• Cost-optimization before committing to drilling

Package Advantages

• Non-invasive: No drilling disturbance
• Cost-effective: Reduces overall investigation costs
• Risk Reduction: Identifies surprises before drilling
• Large Coverage: Surveys wide areas efficiently
• Integrated: Seismic + Resistivity = complete picture
• Strategic: Guides optimal drilling strategy

Typical Deliverables

• 2D seismic sections and profiles
• Velocity models and depth conversions
• 2D resistivity cross-sections
• 3D resistivity models (where applicable)
• Integrated subsurface interpretation
• Layer boundary depths and thicknesses
• Groundwater level estimates
• Optimal borehole location map
• Comprehensive survey report
• Recommendations for follow-up drilling

Typical Survey Coverage

• Seismic Lines: 2-4 profiles, 200-500m each
• Resistivity Lines: 3-5 profiles, 150-400m each
• Investigation Depth: 20-100m typical
• Site Coverage: 1-5 hectares typical

When to Add Drilling After Geophysics

The geophysical survey often indicates where drilling should occur and what depths are most critical. This guides a more targeted borehole program, reducing the number of boreholes needed and focusing resources on the most important subsurface zones.
