PREFACE

These regulations provide supplementary provisions within the areas under the Petroleum Act and the Petroleum Regulations which have been delegated to the Norwegian Petroleum Directorate, except provisions relating to fiscal measurement issues, which are dealt with in separate regulations. The Ministry of Petroleum and Energy is the appeal body for decisions made pursuant to the regulations. Appeals relating to decisions shall be forwarded through the Norwegian Petroleum Directorate, cf. the Public Administration Act, Chapter VI.

The purpose of these regulations is to promote an effective dialogue and co-operation between the parties responsible according to these regulations and the authorities, and in this connection also provide for cost/benefit evaluations. The regulations are intended to ensure satisfactory data acquisition and reporting etc. and are also intended to ensure that the interests of the fishing industry are taken duly into account in connection with seismic data acquisition.

The regulations are phase oriented according to the same structure as superior petroleum legislation. The first chapter deals with introductory provisions, including definitions. Chapters 2 and 3 deal with special requirements applicable to the period prior to and during exploration activities and drilling and well activities, respectively. Chapter 4 contains rules relating to naming and classification of deposits, discoveries etc. and Chapter 5 deals with material and information to be submitted or which shall be made directly available to the Norwegian Petroleum Directorate when the activities have been carried out. Chapter 6 contains general provisions.

Information to be submitted shall be communicated via electronic media. Information may in addition be submitted on paper.

The term “submit” means physical, including electronic, transmission to the Norwegian Petroleum Directorate or to someone designated as recipient by the Norwegian Petroleum Directorate. The term “make directly available” means that the supervisory authorities get access to the information via electronic information systems and may retrieve the information themselves as needed.

Comments have been prepared to these regulations, which provide supplementary explanation and guidance in respect of the provisions.

Thematic guidelines to these regulations of specific areas have been prepared. The thematic guidelines are available at the website of the Norwegian Petroleum Directorate.

  • 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

  • oil, NGL and condensate per vessel

 

Section 29.
Contents of annual status report for fields in production

The report shall provide information to the authorities on matters relating to production on the field, including measures taken during the preceding period, and measures planned to be carried out in the coming year. The report shall also contain necessary explanations in respect of prognoses and resource estimates given in national budgeting reports, including basic assumptions, and of amendments in relation to the previous year’s report.

The following main issues shall be covered in the report:

  • general field status,
  • activity report,
  • plans for the period ahead.
