Borehole Geophysics

It supports projects that need direct depth-controlled measurements to complement surface geophysics and borehole logs.

Definition

What this method is

Borehole geophysics uses downhole measurements to characterize subsurface conditions with depth and improve confidence in engineering interpretations.

It supports projects that need direct depth-controlled measurements to complement surface geophysics and borehole logs.

How It Works

From field measurement to interpreted model

  1. 1Borehole details, depth targets, and project objectives are reviewed during planning.
  2. 2Appropriate downhole measurements are acquired at defined depth intervals.
  3. 3Results are integrated with geology and surface geophysics for decision-focused reporting.

When to Use

Best-fit conditions for this method

  • Projects requiring borehole-based velocity or geophysical control
  • Calibration of surface geophysical models
  • Integrated geotechnical and geophysical interpretation programs

What It Can Help Identify

Subsurface features and signals

  • Depth-specific changes in physical properties
  • Intervals that require additional direct validation
  • Correlation points between borehole and surface datasets

Deliverables

What you receive

  • Borehole geophysics logging summary
  • Depth-interval interpretation tables
  • Integrated correlation notes

Typical Outputs

What the data looks like

  • Logging profile plots
  • Depth-based interpretation summary
  • Correlation panels

Applications

Common applications in the Philippines

Infrastructure and foundation investigations

Groundwater and mining interpretation support

Method Limitations

What this method cannot do alone

  • Requires suitable boreholes and site access for instrumentation.
  • Data quality depends on borehole condition and logging control.
  • Best results are achieved when integrated with geology and direct investigations.

Geophysical results are interpreted models based on measured physical property contrasts. Results should be correlated with boreholes, test pits, drilling, geological mapping, laboratory data, or other direct investigation methods where required.
