Proposal

This proposal suggests a new tag man_made=borehole for Boreholes, which may be used for bores that are not covered by man_made=petroleum_well or man_made=water_well.

It also proposes that the tag direction=extraction/injection/both may be used in combination.

Rationale

There is already a tag for petrol/oil/gas wells: man_made=petroleum_well. There is also a tag for water wells, man_made=water_well.

However, none of these work for geothermal bores, or boreholes used for monitoring/probing/research.

Tagging

They should be mapped as a Node, tagged with man_made=borehole. Just like petroleum_well and water_well.

There are two relevant subkeys:

• substance=* - the substance coming in or out of the bore, if any
• direction=extraction/injection/both - whether the substance is coming out of the ground, or into the ground. See Injection well. If not specified, extraction is implied by default.

Purpose of the bore	Tag
Extraction of petrol/oil/gas	man_made=petroleum_well + substance=petrol/oil/gas
Extraction of water	man_made=water_well
Extraction of geothermal steam	man_made=borehole + substance=steam + (direction=extraction - optional, implied)
Extraction of superheated geothermal water	man_made=borehole + substance=hot_water + (direction=extraction - optional, implied)
Re-injection	man_made=borehole + substance=* + direction=injection
Both re-injection and extraction	man_made=borehole + substance=* + direction=both
Environmental monitoring	man_made=borehole
Geotechnical investigation	man_made=borehole
Probing for a substance	man_made=borehole
Research	man_made=borehole
Measuring temperature	man_made=borehole
Unknown purpose or unknown substance being extracted	man_made=borehole

Discouraged tag combinations:

• man_made=borehole + substance=petrol/oil/gas - in most situation you should use man_made=petroleum_well instead
• man_made=borehole + substance=water - in most situation you should use man_made=water_well instead

Note:

• As always in OSM, if a bore is only used temporarily and then filled back up, you should not map it.
• If the physical hole or structure remains, but is not being used, then man_made=borehole can be used with disused=yes

Examples

• 
  Many geothermal bores feeding into a network of pipelines
• 
  A geothermal bore
• 
  The inside of a borehole
• 
  A Drilling rig digging a bore

Rendering

Maps that render man_made=petroleum_well should consider rendering this tag.
