How Our Geology Estimator Works
Location Input
Enter your address or click the map. Our system identifies your exact coordinates and begins searching for nearby well data.
AI Analysis
Our AI examines up to 50 nearby well logs, extracting geological data, water levels, and drilling details from technical reports.
Detailed Report
Receive a layer-by-layer geological prediction with depth estimates for residential and high-capacity wells, plus construction recommendations.
What Your Geology Report Includes
Geological Layer Analysis
- Layer Types: Clay, sand, gravel, limestone, sandstone, granite, etc.
- Depth Ranges: From/to depths for each geological formation
- Characteristics: Color, hardness, caving potential
- Water Bearing: Which layers likely contain water
Drilling Depth Estimates
- Residential Depth: For typical household use (5-15 GPM)
- High-Capacity Depth: For irrigation/commercial (50+ GPM)
- Static Water Level: Natural water table depth
- Confidence Level: Based on nearby well density
Construction Recommendations
- Drilling Method: Rotary, cable tool, or air rotary
- Casing Depth: How deep to seal the well
- Screen Placement: Optimal intake zones
- Grouting: Cement depth requirements
Key Insights & Warnings
- Drilling Challenges: Hard rock, caving sands, etc.
- Water Quality: Known issues in your geology
- Cost Factors: Depth and difficulty indicators
- Success Rate: Based on nearby well performance
Why Understanding Geology Matters
Knowing what's beneath your property before drilling can save thousands of dollars and prevent project failures.
Every geological layer affects drilling difficulty, well construction, and water quality. Understanding these variations helps you budget accurately, choose the right contractor, and avoid dry holes.
Estimate Your Geology NowCaving Sands
Loose sand layers that collapse, requiring special screens
Hard Bedrock
Granite or quartzite that slows drilling and increases costs
Multiple Aquifers
Different water-bearing zones at various depths and qualities
Clay Barriers
Impermeable layers that protect or isolate water sources
Frequently Asked Questions
How accurate is the geology estimate?
Our AI-powered estimates are based on actual well logs from your area, typically achieving 80-90% accuracy for major geological formations. The tool analyzes up to 50 nearby wells to predict subsurface conditions. However, geology can vary significantly even over short distances, so actual conditions may differ. Always confirm with professional drilling and consider a test bore for critical projects.
What data sources does the estimator use?
The estimator uses DrillerDB's database of millions of well logs filed with state agencies. It analyzes the 5 closest well logs with detailed PDFs and up to 50 additional wells in your area. Our AI examines drilling reports, geological descriptions, water levels, and construction details to create a comprehensive prediction of your site's geology.
How deep will my residential well need to be?
Well depth depends on your local water table and aquifer conditions. Our estimator provides both a residential depth estimate (for 5-15 GPM household needs) and a high-capacity estimate based on analysis of nearby wells. Most residential wells range from 100-500 feet deep, but some areas require 800+ feet. The tool will give you a specific estimate for your location.
Can I use this for commercial or irrigation wells?
Yes! The estimator provides both residential and high-capacity depth estimates. High-capacity estimates are useful for irrigation, commercial, or industrial applications requiring 50+ GPM. However, for large projects, we recommend combining this estimate with professional hydrogeological surveys and possibly test drilling.
Why does the estimate take up to a minute?
The AI needs time to analyze multiple well logs, extract geological data from PDFs, identify patterns, and generate a detailed layer-by-layer prediction. It's essentially reading and interpreting dozens of technical documents to create your personalized geology report. The wait ensures you get the most comprehensive analysis possible.
What if no well data exists for my area?
If insufficient well data exists within a reasonable radius (typically 10 miles), the tool will notify you. In such cases, you may need to expand the search radius or consult with local drillers who have experience in your specific area. Remote or newly developed areas may have limited historical drilling data available.
