Bohrtiefe
Bohrtiefe is a term used in geology, mining, and drilling engineering to denote the maximum depth reached by a borehole from the ground surface. In German-language technical literature, it describes how deep a borehole extends and is often reported as the end depth of the hole. The concept is distinct from the depth to a particular horizon or target interval, which may be specified separately.
The term applies across multiple disciplines, including groundwater exploration, mineral and hydrocarbon prospecting, geothermal drilling, and
Measurement and documentation are standardized in borehole logs. The depth is measured from the ground surface
Several factors influence feasible Bohrtiefe. Geological hardness, groundwater inflows, rock instability, and the performance limits of
In practice, Bohrtiefe serves as a key parameter for resource estimation, hydrogeological assessment, and engineering design,
