Borehole logging 

Borehole logging provides continuous information with depth of physical properties that are vital for most environmental and water resources investigations. 

In COWI we tailor our logging services to our clients' needs due to the stackable capability of the probes. This way we can conduct a wide combination of measurements on the same log run.

The equipment is installed on a 4WD all-terrain vehicle for easier access to borehole locations.

We employ the following advanced probing equipment in our logging operations:

• Fluid conductivity and temperature
• Impeller and heat-pulse flowmeter
• Full waveform sonic
• Natural gamma
• Vertical seismic profiling
• Focused resistivity
• EM dual induction
• Porosity
• Density
• Caliper
• Video inspection

Taking advantage of areas with existing boreholes our wide range of logging capabilities are used in the following applications:

• Soil characterization
• Determining hydraulic properties
• Identifying geologic structures
• Stratigraphic correlation
