Well integrity

The Offshore Petroleum and Greenhouse Gas Storage (Resource Management and Administration) Regulations 2011 commenced on 29 April 2011. NOPSEMA is responsible for the administration of the Well Operations Management Plans (WOMP) and approval of well activities' under Part 5 of these regulations.

Amendments to the Offshore Petroleum and Greenhouse Gas Storage Act 2006, effective from 28 April 2020 introduce additional NOPSEMA inspection powers to monitor and enforce compliance with well integrity laws, including compliance with well operations management plans.

NOPSEMA guidance note Well operations management plan content and level of detail guidance note provides information to assist titleholders on the content and level of detail to be included in WOMP submissions.

Submissions

WOMPs, applications to undertake well activities, well activity notifications and end of abandonment reports along with the applicable form should be submitted via the instructions provided on the Submitting a regulatory document and in compliance with Regulation 11A.01(2) of the Offshore Petroleum and Greenhouse Gas Storage (Resource Management and Administration) Regulations 2011.

Before an activity takes place, the titleholder must produce a well operations management plan (WOMP) that demonstrates to NOPSEMA that:

  • the well is safe

  • the environment and well reservoirs are protected

  • any risks have been reduced to ALARP.

If we reject a WOMP, the titleholder has an opportunity to modify the plan and resubmit it for assessment.

Well integrity compliance is monitored and regulated through inspections, investigations and enforcement action.
