Well safety and monitoring

Constructing and abandoning wells

All wells must be drilled and completed in accordance with safety and other requirements of the Petroleum and Gas (Production and Safety) Regulation 2004 (PDF, 1.3MB) (see Chapter 2 Part 2, Chapter 3 Part 3 and Schedule 1 Part 1).

All wells must be plugged and abandoned in accordance with the Regulation (see s. 292, s. 60 and Schedule 3 of the Regulation).

The Code of practice for constructing and abandoning coal seam gas wells and associated bores in Queensland (PDF, 575KB) applies to all CSG wells drilled from 1 January 2012.

The code ensures that CSG drilling activities are carried out in a consistent manner and that the life of a CSG well is managed effectively from start to finish through appropriate design and construction techniques.

The Code of practice for construction and abandonment of petroleum wells and associated bores in Queensland (PDF, 1.6MB) provides guidance for petroleum well drilling activities are carried out in a consistent manner and that the life of a well is managed effectively from start to finish through appropriate design and construction techniques.

Reporting requirements

You must notify us before you start drilling a petroleum well and when you complete drilling. You must also notify us and provide a report if you decommission or abandon the well. Special notices are required if you intend to conduct hydraulic fracturing (fraccing). Read about your reporting requirements for petroleum wells.

Detection and reporting of leaks and emissions

Queensland's CSG industry must comply with the Code of practice for coal seam gas well head emissions detection and reporting (PDF, 1.4MB), which sets a world's best practice standard for detecting, fixing and reporting CSG well head leaks. The code requires operators to:

  • immediately fix leaks over the reportable level, even in cases when there are very low volumes of gas
  • report on their detection and remediation activities.

The code of practice is currently being expanded to cover all well head emissions.

Well head monitoring program

In 2010-11 the Queensland Government implemented an audit program to review and monitor the safety of CSG wells.

Results of the program found that of the more than 2700 well heads tested, 98% showed no reportable leaks; all detected leaks have been fixed.
