Comparable well evidence
The report should show nearby well logs and explain what they can and cannot say about a geothermal site.
Geothermal Feasibility
Evidence guide
Well Logs for Geothermal Pre-Feasibility
Nearby well logs can help qualify geothermal prospects by showing depth, water, lithology, and sparse-evidence warnings before a paid design conversation.
Well evidence helps explain drilling context, but thermal conductivity must remain an uncertainty until better data exists.
Thermal uncertainty
Thermal conductivity should be represented as a confidence-banded assumption, not a final design value.

Evidence inputs
Nearby well logs
DrillerDB evidenceShows depth, water, and formation context around an address.
Limitation: Nearby wells do not prove actual loop performance.
Static water and lithology context
DrillerDB evidenceSupports drilling and constructability review.
Limitation: Thermal assumptions require qualified review and, when needed, test data.
Report logic
What the page should teach
- Show comparable wells by distance band.
- Flag sparse nearby evidence.
- Explain thermal conductivity uncertainty plainly.
Human-review boundary
- The screen does not replace engineering design.
- The screen does not finalize loop sizing.
- Actual site conditions and permitting still govern the work.
