Borehole orientation surveys: Results from a benchmark study

Determining the orientation or trajectory of any geological borehole is every bit as important as the core or other<br>information that may be extracted from the borehole. Uncertainties in the location of geological contacts, structures,<br>etcetera, which propagate into uncertainties in resource volume calculations, increase the risk associated with resource<br>evaluation projects and may even lead to resource discounting factors being introduced.
