Shallow Geothermal Borefield Verification

50-year system.
Zero subsurface
verification.
Until now.

BoreLogger gives geothermal GSHP projects and thermal energy networks documented proof of what was actually drilled.

Who It's For

Different stakes.
Same need for verified geometry.

For Engineers & Designers
Iterate GSHP thermal design on real borehole geometry, not assumptions.
  • Confirm installed spacing and verticality match your geothermal model
  • Feed actual borefield geometry back into your thermal design — not initial theoretical values
  • Specify borehole deviation verification on dense or boundary-adjacent projects
For Project Owners
Know exactly what's underground — and whose property it's on.
  • Verify bores stayed within your property boundary and thermal energy rights
  • Subsurface as-built documentation for your long-term asset records
  • Verification report for commissioning and regulatory handover
For Drilling Contractors
Add borefield verification to your service offering.
  • New differentiated service line for geothermal GSHP and thermal energy network projects
  • Assistant driller can easily deploy on a standard line
  • Deliver professional verification reports to engineering clients

Assumed → measured, in three tiers.

Tier 01 · Geometry

Where the bores actually went.

A 3D as-built survey of every bore — drift, property-line excursions, and collision risk, before they cost you a redrill.

  • True 3D trajectory, foot by foot
  • Bottom-holes flagged when they leave your property
  • A probabilistic drilling plan & bore-by-bore sequence

✕ Collision · $65/ft redrill
Tier 02 · Capacity

What that does to your capacity.

We recompute the field’s real thermal capacity on the measured geometry — the gain or loss the vertical design never saw. Critical for dense Cold-UTES for data-center cooling fields, where clustering quietly kills capacity.

  • As-built g-function on the measured field
  • Thermal interference mapped, depth by depth
  • Capacity gain or loss vs the vertical design
as-built g-function
Tier 03 · Conductivity

Measured, not assumed.

A Thermal Response Test with fiber-optic DTS logging — measured conductivity at every depth, and the groundwater and grout voids a single bulk number hides.

  • A conductivity profile, not an average
  • Groundwater and grout-void flags by depth
  • A capacity number you can size the plant on
