A list of drilling methods routinely used by the mineral and energy resource industries. The drilling methods are grouped into three main categories based on the dominant motion of the drillstem (i.e. the string of pipe that transmits power from the surface down to the drillbit) and drillbit (the part of the bottom-hole assembly that cuts, grinds or breaks the bottom-hole formation to make the hole). Specifically, the presence/absence of rotation in either or both is used as the main distinguishing factor, hence the main grouping into rotary, non-rotary and hybrid.

This vocabulary covers the common terminology and concepts used in the mineral and energy industries to fully depict the 3D extent of a borehole (i.e. its position in space and the depth reached) or the position of any point along the borehole. The list focuses on the primary and some derived/calculated parameters that are part of reporting for drilling activities, and does include specific processes/procedures related to the acquisition of some of these parameters (e.g. downhole directional survey).

Methods used to spatially locate features observed in the field (e.g. site/outcrop descriptions, structural readings, etc.), data obtained from legacy documents (e.g. airphotos, maps, previously published reports), or the position of exploration, mining and related infrastructure features. Each location method has a spatial accuracy that indicates the maximum estimated approximate error in the location.

A list of units of measurement (UoM) relevant for geoscience and the administration of statutory submissions from the resource industries. The list is based on the Geological Survey of Queensland (GSQ) Geoscience Profile of the Quantities, Units, Dimensions & Types (QUDT) ontology and vocabularies lists (https://linked.data.gov.au/def/geou and https://www.qudt.org/doc/DOC_VOCAB-UNITS.html - version 2.1.29).
