🌊 HydroPick — Professional Software for Groundwater Detection
Advanced ADMT & PQWT Data Processing with 1D Resistivity Inversion
 
💧 Find the Best Location to Drill a Water Well
HydroPick is an advanced geophysical software developed by GeoExplorer Solutions to process and interpret Spontaneous Potential (SP) data from ADMT and PQWT instruments.
The software converts complex frequency-domain measurements into clear geophysical models that reveal groundwater-bearing zones, fractures, and subsurface structures.
With HydroPick, geophysicists can quickly identify the most promising drilling locations, reducing exploration risk and increasing drilling success.
 
🚀 Why HydroPick?
HydroPick was designed specifically for groundwater exploration professionals who work with ADMT and PQWT systems.
Instead of manually interpreting complex frequency curves, HydroPick automatically processes the data and generates:
✔ 2D subsurface anomaly maps
✔ 1D resistivity inversion models
✔ Automatic drilling target detection
✔ Professional interpretation graphics
This allows you to move from raw field data to a clear drilling decision in minutes.
 
🔬 The Science Behind HydroPick
Frequency Spectrum Method (FSM)
HydroPick is based on the Frequency Spectrum Method, a geophysical technique that analyzes how different subsurface materials respond to electromagnetic signals across multiple frequencies.
Different geological materials produce unique electrical responses:
Material
Typical Response
Fractured rock
Low frequency anomalies
Water saturated zones
Strong SP signals
Clay layers
Distinct electrical signatures
Competent bedrock
Stable high resistivity
By analyzing the entire frequency spectrum simultaneously, HydroPick identifies fractures, aquifers, and lithological boundaries with high confidence.
 
The method relies on electrokinetic effects, where groundwater flow through porous or fractured media generates streaming potentials, producing measurable SP anomalies at the surface.
📊 What HydroPick Delivers
 
1️⃣ 2D Subsurface SP Imaging
HydroPick generates full-color geophysical sections that display:
• Lateral extension of groundwater zones
• Depth to potential aquifers
• Structural features and fractures
• Geological layer boundaries
These images allow fast visual interpretation of the subsurface.
 
2️⃣ 1D Resistivity Inversion Models
For any point along the survey profile, HydroPick calculates a 1D resistivity model, showing:
• Layer resistivities
• Depth to geological interfaces
• Thickness of saturated zones
• Bedrock depth
This inversion helps transform SP measurements into quantitative geological information.
 
3️⃣ Automatic Drilling Target Selection
HydroPick automatically analyzes the processed data and identifies the best drilling locations based on:
• SP anomaly strength
• Vertical extent of the conductive zone
• Lateral continuity
• Data confidence
 
The software highlights the optimal point to drill, minimizing uncertainty.
⚙ Advanced TRF Inversion Algorithm
At the core of HydroPick is the Trust Region Reflective (TRF) inversion algorithm, a robust mathematical approach used to estimate subsurface resistivity models.
The inversion converts measured SP signals into physical resistivity values:
Measured SP Data → Mathematical Inversion → Resistivity Layer Model
 
Key advantages:
✅ Physically constrained solutions
✅ Stable results even with noisy field data
✅ Smooth and realistic layer models
✅ RMS error and quality indicators
