Health and safety guidelines for shallow geothermal wells

We have produced guidance intended to provide sufficient mandatory rules, recommendations and commentary to enable shallow geothermal wells to be drilled and operated safely.

While this guidance has not been updated to reflect current work health and safety legislation (the Health and Safety at Work Act 2015 and regulations), it may still contain relevant information and practices to keep workers and others healthy and safe.

Please read this guidance in conjunction with all relevant industry standards that apply to you as a PCBU. This guidance will be progressively reviewed and either updated, replaced with other guidance, or revoked.

Health and safety for shallow geothermal wells

Health and safety guidelines for shallow geothermal wells sets out the requirements for design and work practice necessary to ensure the safe drilling, operation, maintenance and abandonment of wells penetrating hot subsurface conditions to a depth of 150 metres, however where subsurface conditions are not expected to be severe, compliance with these guidelines may be extended to those wells drilled to a depth not exceeding 250 metres.

These guidelines apply particularly to the volcanic regions and geothermal industry of New Zealand, but are expected to be suitable for use in other countries.
