Data submissions

Division 3 of the Offshore Petroleum and Greenhouse Gas Storage (Resource Management and Administration) Regulations 2011 (RMA Regulations) outlines the submission requirements for reports, data and samples provided under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act). Important details including specific content, formats and media for reports, data, core and samples are outlined in the relevant sections and schedules.

NOPTA has developed detailed guidelines for the reporting and submission of offshore petroleum data and these are available below.

Data submissions are to be directed to either NOPTA or the National Offshore Petroleum Data and Core Repository (NOPDCR), (refer to submission addresses page). Complete reports and data submissions are preferred and any variations to submission timelines, contents or format require the advance approval of the Titles Administrator. Please refer to variation to data submission requirements section below for more information.

Where basic and interpretative data are mixed on a single medium, those submitting the data must ensure that basic and interpretative volumes are identified and provided as separate files—and clearly marked on both the medium and accompanying transmittal. NOPTA prefers basic and interpretative volumes to be submitted on separate media to avoid difficulties in the classification of data.

Regulatory requirements for well data

Notification of well activities

Titleholders are required to provide advance details of defined well activities (including drilling and well workover programs) under Part 5 of the RMA Regulations. This is usually provided as part of the well operations management plan (WOMP) approved by the National Offshore Petroleum, Safety and Environmental Management Authority (NOPSEMA), the regulator as defined in Regulation 5.02. Under Regulation 5.28, titleholders are also required to provide a copy of the appropriate documents to NOPTA.

Well Operations Management Plans (WOMPs) and other well activity notifications should be forwarded to resources@nopta.gov.au.

Daily drilling reports

‘Daily drilling reports’ (Regulation 7.12) must be submitted to NOPTA at reporting@nopta.gov.au by midday on the day after the day to which the report relates.

Initial well completion reports and data

‘Initial well completion reports’ (Regulation 7.13) and all ‘initial well completion data’ (Schedule 1 of the RMA Regulations) must be submitted to NOPTA within six months of rig release date unless otherwise authorised.

Final well completion report and data

‘Final well completion reports’ (Regulation 7.14) and all ‘final well completion data’ (Schedule 2 of the RMA Regulations) must be submitted to NOPTA within 18 months of rig release date unless otherwise authorised.

Petrophysical, geochemical or other sample analysis submission

Regulation 7.14 (Schedule 2 of the RMA Regulations) now allows petrophysical, geochemical or other sample analyses to be submitted as part of the final well completion dataset. However, it will continue to be classified as basic information.

This dataset was previously submitted as 'basic data' under the Petroleum (Submerged Lands) (Data Management) Regulations 2004. The change in submission timing was adopted after consultation with industry to accommodate the time required to complete the analyses.

To assist with processing the public release of this dataset, titleholders may submit the dataset as part of the final well completion submission under Schedule 2 of the RMA Regulations, as separate files to that report.

Where these basic data items are available at the time the initial well completion report and associated data is due, NOPTA prefers it is provided with the initial well completion report submission.

Please note that although all care is undertaken, the Titles Administrator and the NOPDCR cannot take responsibility for the inadvertent release of data where items have been incorrectly labelled, or provided in a way contrary to these requirements or those of the RMA Regulations.

Well workover operations

Well workovers are defined in Regulation 5.02 as an approved activity under the RMA Regulations and have particular daily and summary reporting requirements.

These requirements are outlined in Table 8.2 of the Guidelines for reporting and submission of offshore petroleum data.

Regulatory requirements for survey data

Notification of survey activities

Regulation 12.07 of the RMA Regulations outlines the requirement to provide 48 hours notice of the commencement of all geophysical or geological surveys. Information to be provided includes the proposed date and time of survey commencement, the anticipated duration of the survey, survey area coordinates and for seismic surveys, the length of streamers to be towed by the survey vessel. Survey notifications should be forwarded to reporting@nopta.gov.au.

Weekly survey reports

‘Weekly survey reports’ (Regulation 7.15) must be submitted to NOPTA at reporting@nopta.gov.au as soon as practicable after the end of each week of the survey.

Survey acquisition report and data

A ‘survey acquisition report’ (Regulation 7.16) and ‘survey acquisition data’ (Schedule 3 of the RMA Regulations) must be provided within 18 months after the day that acquisition of the data is completed, unless otherwise authorised.

Notes on field data

Due to the volume of data, field tapes are submitted directly to the NOPDCR Canberra repository. A copy of the field tape listing and load information should accompany this submission

Survey processing report and data

A ‘survey processing report’ (Regulation 7.17) and ‘processed survey data’ (Schedule 4 of the RMA Regulations) must be provided to NOPTA within 24 months after the day that the acquisition of the data is completed, unless otherwise authorised.

Survey interpretation report and data

A ‘survey interpretation report’ (Regulation 7.18) and ‘interpretative survey data’ (Schedule 5 of the RMA Regulations) must be provided to NOPTA within 30 months after the day that the acquisition of the data is completed, unless otherwise authorised.

Reprocessed survey data

Reprocessed survey data should be submitted only where the reprocessing is completed to satisfy a condition of the grant of a title.

Wherever possible, the Titles Administrator expects submission of reprocessed survey data to mirror the requirements for newly acquired surveys. Although a full interpretative submission is required, the basic submission will be comprised of the processing report and processed survey data only.

Basic reprocessed data—the processing report and processed data—is required to be submitted at the end of the title year (anniversary of title grant) in which the activity was completed.

The interpretation report and data is expected to be received 12 months after the end of the title year (anniversary of title grant) in which the activity was completed.

Table 8.5 of the Guidelines for reporting and submission of offshore petroleum data provides information on submission requirements of reprocessed data created as part of a work program.

Non-exclusive and licensed survey data

The RMA Regulations define non-exclusive data as ‘data that is made available for commercial sale or license’ (Regulation 1.05).

The number of surveys acquiring non-exclusive data has increased significantly in recent years; with many titleholders licensing this data to meet their title conditions.

For some 3D surveys acquiring non-exclusive data, a condition to the grant of title may include the requirement to produce a 2D extract.

This extract must be submitted in a 5km x 5km grid and will be made publicly available earlier than the 3D deliverables.

The Titles Administrator does not expect to receive an interpretative data submission from the titleholder that has conducted the survey acquiring non-exclusive data.

However, where survey data has been purchased or licensed to meet a title condition, the Titles Administrator expects to receive a survey interpretation report and data derived from that data from the licensee.

This may be limited to the title area for which the condition relates.

Variation to data submission requirements

A variation to the submission requirements for an offshore petroleum activity may be authorised by the Titles Administrator under Part 7 of the RMA Regulations. Variations that may be considered include extended submission timing, non-standard media/format submissions or combined submissions.

A request to vary submission requirements should be directed to data@nopta.gov.au and include:

  • title number(s)
  • activity details, such as well or survey name
  • the relevant regulation in which the request is being made (which submission requirement)
  • the relevant report or data type
  • the reason for the request
  • requested alternative, for example new submission date or data format
  • any foreseeable impact the request may have on the availability of data for public release.

The submission variation approval number should be quoted on the relevant data submission transmittal(s).
