Borehole logging
A detailed record of every geological formation a borehole passes through — by eye at the core box, and by instrument down the hole.

Sectors
The two kinds of log
By eye, and by instrument.
- Geological logs
- Based on visual inspection of samples brought to the surface. Recovered cores are examined by eye and then in detail.
- Geophysical logs
- Based on physical measurements made by instruments lowered into the hole. Some geophysical logs can be run during any phase of a well’s history — drilling, completing, producing or abandoning.
What we record
From each core run
- Lithology
- Dip and strike
- Type of weathering
- RQD — rock quality designation
- Core recovery
- Lugeon value
Well logging is performed in boreholes drilled for oil and gas, groundwater, mineral and geothermal exploration, and as part of environmental and geotechnical studies.
