: Using precise winches and measuring sheaves to correlate data with exact depth.
Geophysical borehole logging is essential for understanding subsurface properties without extensive excavation. This paper examines the frameworks established by ISO/TR 14685:2001 , which provides guidelines for making hydrometric determinations through borehole measurements.
The standard details the use of —cable-suspended probes containing sensors—to measure physical parameters. Key technical considerations include:
: Assessing the chemical and physical properties of the water or other fluids present.
: Identifying the types of rock or soil layers penetrated.
