Guidelines for Production Reporting - Oljedirektoratet

1 Guidelines for Production Reporting Legislation Reporting of petroleum Production is regulated in the Petroleum Act Section 10-4, The Petroleum Regulations Sections 27, 48 and 49 and the Resource Management Regulations Sections 27 and 28. What should be reported? Resource Management Regulations Section 27. Daily reports during the Production phase Information relating to the most important Production parameters such as gross/net Production shall be made directly available to the Norwegian Petroleum Directorate (NPD) on a daily basis.

2 Resource Management Regulations Section 28. Monthly Reporting of Production data The following volume data shall be reported on a monthly basis: Production - per well/wellbore and facility, - allocated marketable products per facility/field (value adjusted), - import/export per facility/structure, - consumption (flare, fuel, diesel etc.) per facility/structure. Injection - per well/wellbore and facility Stock - quantities at end of month Sales - gas per owner and buyer, - oil, NGL and condensate per vessel. Who should report?

3 The licensees in Production licenses are legally responsible for fulfilling the Reporting obligations. Under normal circumstances, the operator of the Production license/ unit in which the producing field is located, reports the data on behalf of the licensee group. According to regulations, produced and injected quantities shall be provided for each individual field (as listed in the NPD Fact Pages). If these quantities cannot be measured separately, the reported numbers shall reflect the approved allocated quantities. Where to report?

4 The Production report shall be sent to the NPD. The NPD can decide if the operators shall report directly to a sub-contractor which stores the data on behalf of the authorities (such as the DISKOS database). However, this has not been decided yet (2011). There is currently no legislation regarding how the NPD should receive the daily Reporting of Production data, but the existing practice is that the NPD downloads the data from the L2S (License2 Share) portal, which the licensees have decided shall include daily Production data.

5 Alternatively, operators can send the data as an attachment in an e -mail. The NPD will control the quality of the data before downloading it to DISKOS. The quarterly Reporting of sales, according to the Petroleum Regulations S ection 49, shall be sent to the Ministry of Petroleum and Energy. Access to data By using the NPD Fact Pages, the public has access to some of the data which has been reported. The data can be downloaded in various formats. The official Production figures are published every month on the NPD Fact Pages.

6 Detailed specification A tailor made ASCII format (COPEX) has been used since 2000 for monthly Reporting of Production and sales data to NPD. See attachment 1. The NPD has developed a new XML format based on the PRODML standard from Energetics and is named MPRML ( montly Production Reporting Markup Language). The work has been done in cooperation with the industry (Norwegian Oil and Gas Association). This format was first used in 2013 for Reporting of Production data from the sgard field. For a transitional period both the MPRML and the COPEX formats will be used, but MPRML will gradually be implemented as the main format.

7 NPD is preparing (2013) a migration plan together with the operators of the fields with an aim for a speedy transition. Attachment 1 EXAMPLES OF Production AND SALES DATA Reporting TO THE NPD The existing PPRS format will be replaced by a new format COPEX. (Common Petrotechnical Exchange format) which is an ASCII based format. The NPD s PPRS database was replaced by Petrobank in January 2000. All information here will be available to all Diskos members. All information must be reported in Copex format. The licensee submitting the data is responsible for the data quality.
