Conducting activities after approval

If you carry out activities for geophysical or aerial surveys, well drilling and petroleum recovery after approval, you must submit reports of these activities.

Read below for more information.

Once you start the geophysical survey, you must produce a weekly survey report to the Petroleum Operations team.

After you complete the survey

Once you complete the geophysical survey, you must:

  • complete clean up and demobilisation from survey site
  • ensure the environment is rehabilitated as per the approved environmental management plan
  • supply periodic report for environmental rehabilitation
  • confirm rehabilitation is complete - this may involve third party validation.

An assessment of the final environment rehabilitation report will take place prior to release of the security deposit.

Once you start the aerial survey, you must produce a weekly survey report to the Petroleum Operations team.

After you complete the survey

Once you complete the aerial survey, you must submit survey completion reports and data sets to the Petroleum Data Management team.

For well drilling and workover, you must complete a well plan summary.

Well plan summary

You must provide a well plan summary seven days before starting well activity under an approved well operations management plan (WOMP).
