(Resource Management Regulations)

 

Legal basis: Laid down by the Norwegian Petroleum Directorate on 13. December 2017 pursuant to Section 10-18 of Act No. 72 of 29 November 1996 relating to petroleum activities, cf. Section 6 ninth paragraph of Regulation No. 653 of 27 June 1997 relating to the Act relating to petroleum activities, Sections 46, 47, 48, 53, 74, 79 and 86, cf. administrative decision No. 512 of 15 May 2009. Last amended by Regulation of December 19 2017 No 2244.

 

Chapter 1
Introductory provisions

 

Section 1
Objective 

These Regulations will provide supplementary provisions concerning data acquisition and documentation within the areas subject to Act No. 72 of 29 November 1996 relating to petroleum activities (the Petroleum Act) and Regulation to Act No. 653 of 27 June 1997 relating to the Act relating to petroleum activities (the Petroleum Regulations) that have been delegated to the Norwegian Petroleum Directorate. These Regulations shall also safeguard the consideration for third parties in connection with seismic data acquisition.

 

Section 2
Scope
 

These Regulations shall apply for resource management in the petroleum activities in areas covered under Section 1-4 of the Petroleum Act.

 

Section 3
Definitions
 

These Regulations use the following definitions:

a) Appraisal well: well drilled to determine the extent and size of a petroleum deposit that has already been proven with a wildcat well,

b) Cuttings: rock fragments from the drilling process,

c) Drilling programme: description containing well/wellbore-specific information concerning planned drilling and well activity,

d) Well: hole that is drilled to find or delineate a petroleum deposit and/or to produce petroleum or water for the purpose of injection, to inject gas, water or another medium, or to map or monitor well parameters. There are several categories of wells. A well can consist of one or more wellbores and can have one or more termination points,

e) Well activity: facilitation and implementation of operations in connection with completion, data acquisition, monitoring, control, overhauling, modification and plugback of existing wells,

f) Wellbore: describes the well's location from one termination point to the wellhead,

g) Well target: the geological unit(s) the well will be drilled into (geological well target) and the wellbore's termination point; includes geographical coordinates and depth in metres (drilling operational well target),

h) Boat km: describes a seismic vessel's sailing distance

i) CDP km: refers to Common Depth Point. Describes the number of line kilometres of seismic data acquired and depends on the number of hydrophones and the number of signal sources used. If one hydrophone is used (2D seismic), this will correspond to boat km,

j) Field: a petroleum deposit, or several petroleum deposits together, that are covered by an approved Plan for Development and Operation (PDO) or has been granted an exemption from the PDO requirement,

k) Formation test: test of an individual well's production or injection properties for no more than 10 flow days,

l) Formation test logging: repeated pressure/test readings in a well (RFT),

m) Discovery: a petroleum deposit, or several petroleum deposits together, which have been discovered in the same wellbore and in which testing, sampling or logging has established the probability of the existence of mobile petroleum,

n) Injection well: development well or test development well that is used for injection of gas, water or another medium,

o) Completion activity: any installation of production flow lines, packers and other equipment, as well as perforation of, stimulation and cleanout in and killing of development wells. Shutdown of reservoir zones or previously perforated intervals, as well as additional perforations is also considered to be completion activity,

p) Exploration well: well that is drilled in order to prove a possible petroleum deposit or to obtain information to delineate a proven deposit. Exploration well is a collective term for wildcat and appraisal wells,

q) Exploration target: the geological unit(s) that the well will be drilled into to prove a possible petroleum deposit that is not included in the resource basis for a field,

r) Observation well: development or test development well that is used to measure specific well parameters or reservoir properties,

s) Production well: development well or test development well that is used for production of petroleum or of water for injection purposes,

t) Prospect: a possible petroleum trap with a mappable, delimited reservoir rock volume,

u) Potential prospect: a potential petroleum trap where available data coverage and quality are not adequate in order to map or delineate the reservoir rock volume,

v) Test development well: well that is used to test production,

w) Wildcat well: exploration well that is drilled in order to investigate (prove) the existence of petroleum in a potential deposit, 

x) Development well: joint designation for wells that are used to produce petroleum; production wells, injection wells and observation wells and possible combinations of these.

Definitions in the Petroleum Act and the Petroleum Regulations apply to this Regulation insofar as they are suitable.

When seismic surveys are started, the audio source must be started up gradually to give fish and marine mammals the opportunity to leave the area around the survey.

Vessels conducting seismic surveys shall maintain a prudent distance to vessels engaged in fishery activities, as well as fixed and floating fishing gear. Particular caution shall be exercised when large groups of fishing vessels are observed.

If vessels conducting seismic surveys are assisted by an escort vessel, this must play a passive role in relation to other users of the sea.

 

Section 9
Requirement to have a fisheries expert on board vessels conducting seismic surveys 

Vessels that conduct seismic surveys must have a fisheries expert on board when this is necessary out of consideration for fishery activities in the area. In the event of doubt, the Norwegian Petroleum Directorate will make the final decision.

The licensee shall report the name of the fisheries expert for the survey no later than five business days before the seismic survey is scheduled to start. The Norwegian Petroleum Directorate may grant exemptions from this deadline.

The fisheries expert should be present at the start-up meeting for the survey in order to provide information about anticipated fishery activity in the area of the seismic survey.

The fisheries expert shall play an advisory role for the survey within their specific discipline and shall be guaranteed a free and independent position. The role of fisheries expert shall be carried out objectively and impartially in the relationship between the principal and fisheries interests.

The licensee and/or the party responsible for operation of the vessel shall make relevant regulations, documents and data available to the fisheries expert. Regulations and documents shall be available in both Norwegian and English. Access to the Internet and other necessary aids for the fisheries expert must be facilitated.


Section 10
Position reporting in connection with seismic surveys
 

Vessels conducting seismic surveys shall have on board and use equipment that monitors and reports the vessel's position and movements. Switching off, damaging, destroying or otherwise manipulating the position reporting equipment during the survey activity is prohibited.

Position reporting equipment pursuant to this provision shall satisfy the requirements in Regulations No. 454 of 24 March 2010 relating to requirements for equipment and installation of position reporting equipment. Section 3 concerning requirements for the service provider that forwards tracking information applies correspondingly.

Vessels starting seismic surveys shall send an electronic notice to the Directorate of Fisheries' 24/7 monitoring centre (FMC), which is designated by the Norwegian Petroleum Directorate as system operator, in order to activate the receipt of signals. The requirement for monitoring and registration starts when the audio sources are activated, and lasts for the duration of the survey.

Vessels conducting surveys shall, twice per hour, and for the duration of the activity, automatically report the vessel's position to the Directorate of Fisheries. The Directorate of Fisheries may acquire the position of the individual vessel more frequently than twice per hour, according to the Norwegian Petroleum Directorate's more detailed directions.

Position reporting shall contain the following information:

a) clear identification of the vessel,

b) the vessel's geographical position at the time of reporting with a position error of less than 500 metres with a confidence interval of 99%,

c) date and time for the vessel's position,

d) speed and course at the time of reporting,

e) identification of the type of report submitted.

 

Section 11
Requirements for fisheries experts on board vessels conducting seismic surveys 

Those serving as fisheries expert must have completed and passed a test for an approved course. The Norwegian Petroleum Directorate shall stipulate the professional content, time and location of such courses and shall issue a course certificate. A fee may be required for participation in the course.

Those participating in the course must be proficient in Norwegian and English and be able to document that they, over the course of the last five years, have been active fishermen for at least twelve consecutive months. One must also document knowledge about fishery activities in the waters where the seismic vessel will be operating, differentiated as south of 62 degrees north, between 62–67 degrees north and north of 67 degrees north. The person in question must, as a minimum, hold a navigation certificate as a class B or D 5 fishing boat skipper without restrictions. A minimum of 1 year of experience as skipper/first officer is also required.

The fisheries expert must, every five years after passing the course, be able to document that, over the last five years, he/she has been an active fisher and/or fisheries expert for at least twelve consecutive months.

The Norwegian Petroleum Directorate has an overview of people who have passed the course and issues verifications of the right to practice as fisheries expert. This verification is valid for five years and must then be renewed. The Norwegian Petroleum Directorate can decide that those who do not fulfil the activity obligation as active fisherman and/or fisheries expert or otherwise do not fulfil their obligations as fisheries expert, may lose their right to practice as fisheries expert.

The fisheries expert is obliged to familiarise himself/herself with the content of the survey or production licence and notice of the survey pursuant to Section 6 of these Regulations. The manual of information for the fisheries expert shall be stipulated by the Norwegian Petroleum Directorate and shall be available during each assignment.


Section 12
Route surveys and other subsurface surveys 

Route surveys and other subsurface surveys shall be carried out pursuant to Section 30 of the Petroleum Regulations and shall be reported in the Norwegian Petroleum Directorate's web-based reporting system for surveys.

Notes on the Regulations relating to resource management in the petroleum activities

 

 

Re Chapter 1
Introductory provisions

 

Re Section 1
Objective

It is presumed that materials and information are submitted or made directly available to the Norwegian Petroleum Directorate, or the party appointed by the Norwegian Petroleum Directorate, cf. Section 10-4 of the Petroleum Act and Section 53 of the Petroleum Regulations. All materials and documentation must be submitted pursuant to the Norwegian Petroleum Directorate's format requirements, guidelines and specifications. These can be found on the Norwegian Petroleum Directorate's website, http://www.npd.no.

Technical measurement provisions and materials and documentation in connection with survey and exploitation of subsea reservoirs on the continental shelf for storage of CO2 is subject to separate regulations.

 

Re Section 3
Definitions

Exploration target: If a deposit, which is included in the resource basis of a field, is reported as a new discovery when the deposit is confirmed upon drilling, the resources will be recorded twice in the accounts. It is therefore not appropriate to use the term "discovery" in connection with deposits that are already included in the resource basis. This issue often occurs when deposits are proven/confirmed in connection with the drilling of development wells.

Discovery: The term discovery includes both commercial and technical discoveries.

 

Re Section 4
Format and units of measurement

Clear identification e.g. means using the Norwegian Petroleum Directorate's unique identification codes (NPID), designations for discoveries and wells.

 

Re Section 5
Responsibilities pursuant to these Regulations

The provision must be seen in the context of Section 10-6 of the Petroleum Act relating to the duty to comply with the Act and to ensure that provisions are adhered to, as well as Sections 56, 57 and 58 of the Petroleum Regulations relating to management systems. It is specified that first paragrph entails a material obligation to comply with provisions of the Regulations, as well as a duty to do this through implementation of necessary systematic measures.

 

Re Chapter 2
Surveys

 

The provisions concerning survey activity in these Regulations must be seen in context with the provisions stipulated in Chapter 2 of the Petroleum Act, as well as Chapter 2 of the Petroleum Regulations.

Applications for survey licence and payments of the survey licence fee and payments of the fee for each seismic survey must be submitted to the Norwegian Petroleum Directorate, cf. Sections 3, 5 and 9 of the Petroleum Regulations.

The provisions in this chapter apply to survey activity within the survey licence, production licence and licence for installation and operation of facilities for transport and exploitation of petroleum.

If the survey entails drilling deeper than 200 metres, one must, in addition to registering the borehole with the Norwegian Petroleum Directorate, also obtain consent from the Petroleum Safety Authority Norway, cf. Section 25 of Regulation No. 611 of 29 April 2010 relating to management and the duty to provide information in the petroleum activities and at certain onshore facilities (the Management Regulations).

Testing of equipment is not governed by the Regulations.

 

Re Section 6
Notification in connection with surveys

The provision supplements Section 6 of the Petroleum Regulations with regard to which information must be submitted in connection with survey activity.

The requirement to report the name of the vessel applies for all vessels involved in the survey.

Survey activity which includes a seismic survey is considered to start when the source is activated.

In the event of reports of temporary suspension pursuant to fifth paragraph, a new reporting will not be required pursuant to second paragraph litera f) unless the temporary suspension entails that the survey will extend beyond the previously reported period. A notice of temporary suspension is not required for brief changes in position.

The Norwegian Petroleum Directorate's reporting system for surveys can be found on the NPD's website, http://www.npd.no.

 

Re Section 8
Requirements in connection with conducting seismic surveys

Gradual start-up of the sound source (soft start) entails that the sound source starts at low output and gradually increases until full output is achieved (usually over the course of 20 minutes).

Section 6 of the Petroleum Regulations contains provisions that will prevent any conflicts of interest. If there is no fishery activity in the relevant area during the period in question, the seismic vessel may start the activity. As long as the vessel has the cables deployed, it is considered to be a vessel with "limited ability to manoeuvre", cf. Rule 3 litera g) in Regulation No. 5 of 1 December 1975 relating to prevention of collisions at sea (Rules of the Road at Sea). Should fishing vessels appear in such situations, they will have to yield the right of way vis-à-vis seismic vessels pursuant to Rule 18 litera c) of the Rules of the Road at Sea. Pursuant to the so-called lex specialis principle, the Rules of the Road at Sea supersede the general right of way provision in Section 8 of these Regulations concerning the obligation for the seismic vessel to maintain a prudent distance to vessels engaged in fishing.

 

Re Section 9
Requirement to have a fisheries expert on board vessels conducting seismic surveys

Pursuant to the provision, "relevant regulations, documents and data shall be made available to the fisheries expert". This also includes the licensee's survey licence or production licence, and any decisions made in connection with the specific survey, including terms and conditions and advice provided in connection with the activity.

 

Re Section 10
Position reporting in connection with seismic surveys

The Directorate of Fisheries' 24/7 Fisheries Monitoring Centre (FMC), is the contact point for technical and practical information about installation and use of position reporting equipment.

 

Re Section 11
Requirement to
have a fisheries expert on board vessels conducting seismic surveys 

Changed certificate requirements will apply for participation in courses as from the date when the regulatory provision becomes effective.

 

Re Section 12
Route surveys and other subsurface surveys

The provision supplements the information requirements stipulated in Section 30 of the Petroleum Regulations.

 

Re Chapter 3
Drilling and well activity, etc.

 

Re Section 13
Naming and classification of wells, wellbores and shallow drilling

The provision supplements Section 46 of the Petroleum Regulations.

The registration form can be found on the Norwegian Petroleum Directorate's website, http://www.npd.no

The Norwegian Petroleum Directorate's systems for well/wellbore names and classification are provided in separate topical guidelines and can be found on the Norwegian Petroleum Directorate's website.

 

Re Section 14
Drilling programme

Reference is made to NORSOK standard D-010 Drilling and well operations, revision 4 for geo-technical content in drilling programmes.

For exploration wells and development wells with exploration targets, the following information should be included in the program:

  • Well information: production licence, licensees, well name, drilling rig (name, owner, water depth, the drill floor/rotary table (RKB), etc.), geographical coordinates, brief history of the production licence.
  • Geological background: regional geological placement, map with scale and geographical coordinates over the production licence with a prospect outline and well placement, lithological column with depth, formations and explanatory text, pressure, temperature.
  • Prospect information: map (time and depth), geological information, velocities, crossing seismic lines through the well, at least one geo-seismic section, volume with probability.
  • Data acquisition: type and recipient (incl. the Norwegian Petroleum Directorate), criteria (for e.g. coring, WL), table with planned formation evaluation.
  • Organisation chart with position, telephone numbers, e-mail addresses.

 

Re Section 17
Information about formation test

The information about formation test should include the following:

  • The purpose of the test and how it will take place
  • Allocation of produced petroleum
  • Overview of costs and income from potential sale,
  • Duration of flow and shut-in periods,
  • Estimated rates for oil and gas, as well as volume indication for emissions to air (burning and cold flaring) and discharges to water,
  • Assessment of environmental consequences,
  • Planned extraction and analysis of formation fluid,
  • Potential planned production logging,
  • Preliminary log evaluation (Computer Processed Interpretations (CPI)) in measured depth (MD) and true vertical depth (TVD) from the reservoir in scale 1:500.

 

Re Section 19
Classification of petroleum resources on the Norwegian continental shelf

Topical guidelines concerning resource classification have been prepared.

 

Re Section 20
Naming petroleum deposits

The provision supplements section 79 of the Petroleum Regulations.

An example of a deposit name is the "33/99-1-deposit". If multiple deposits are proven in the same well, the geological unit is also added, for example the "33/99-1-Paleocene deposit" or "33/99-1-NNdeposit".

 

Re Section 21
Naming discoveries

The provision supplements section 79 of the Petroleum Regulations.

An example of a discovery name is the "33/99-1-discovery". If the discovery is named, the designation becomes "33/99-1 NN".

 

Re Section 22
Designation of permanently placed facilities

The provision is an elaboration of Section 79 of the Petroleum Regulations.

Permanently placed facilities means both facilities resting on the seabed and permanently placed mobile facilities.

This Regulation's provision concerning naming of permanently placed facilities has a different purpose than Section 71 of the Regulations relating to design and outfitting of facilities, etc. in the petroleum activities (the Facilities Regulations), Marking of facilities. Section 71 of the Facilities Regulations governs the design of identity boards on the facilities, which shall provide detailed information to seafarers in the area and shall normally include the field name, in addition to the facility name.

 

Re Section 23
Information about permanent plugging of wells

The deadline for submitting information is one day, but nevertheless as soon as possible. The deadline will primarily be relevant for exploration wells, as information about plugging of development wells can normally be reported earlier.

 

Re Chapter 4
Submitting materials and documentation

 

Re Section 25
Submitting materials and documentation from surveys

This provision supplements the provisions in Section 6 of the Petroleum Regulations.

All materials and documentation must be submitted pursuant to the Norwegian Petroleum Directorate's format requirements and specifications. These can be found on the Norwegian Petroleum Directorate's website, http://www.npd.no.

Materials and documentation discussed in this provision, first paragraph litera a) to d), must be submitted to the Diskos database in accordance with the topical guidelines; Guidelines for reporting geophysical data ("yellow book") and Guidelines for digital reporting for wells ("blue book").

All materials and information that are sent to the Diskos database must be clearly labelled, so that it is evident that this was submitted in accordance with requirements stipulated by the Norwegian Petroleum Directorate.

Materials and information discussed in this provision, first paragraph litera d), must be submitted to the Norwegian Petroleum Directorate.

Upon application, the Norwegian Petroleum Directorate may grant exemption from the routine data reporting requirements, cf. Section 38 of these Regulations. A potential exemption from the reporting duty will be contingent upon field data and pre-stack-data being satisfactorily stored and easily accessible for everyone who wants access to the data, and that they originate from saleable surveys. Should the conditions that the exemption is based on no longer be in place, we will require submission of the data.

Saleable data will be data that is only acquired with the purpose of making the data available for sale to a third party. It is a precondition that the data must be saleable from the time they are available to the owner. This in turn means that the data must be available to everyone at market prices from when they are available to the owner and ready for use. Data that is collected for internal use in one or more production licenses is not considered "saleable".

Licensees that do not normally conduct surveys with the objective of re-selling the data, must document their basis for requesting that a survey be classified as saleable while also reporting data pursuant to Section 6 eigth paragraph of the Petroleum Regulations, cf. last paragraph.

 

Re Section 27
Geo-technical materials and documentation from production licences in the event of relinquishment, surrender, lapse and expiry

This provision is a continuation of and elaborates upon the provisions in Section 20 third paragraph of the previous regulations (FOR-2001-06-18-749). Reference is made to separate topical guidelines at npd.no.

The status report requirement applies to production licenses awarded from APA 2006 and for production licences awarded from the 22nd round (in 2012).

 

Re Section 29
Submitting samples and preparations from wells

The provision must be seen in the context of Section 16 of these Regulations relating to technical geological and reservoir data acquisition in connection with drilling and well activity.

All sample depths shall be stated as measured depth in relation to the drill floor/rotary table (RKB). As regards fluid samples taken as downhole pressure samples, the date and name of the sample-taker shall be stated for both the pressure sample taken at the drilling facility and for subsequent opening of/sampling from the pressure sample in the laboratory. Depth intervals for fluid samples are the same as the perforation intervals. Standard sample bottles for fluid samples can be procured from the Norwegian Petroleum Directorate.

A rig set means 10 - 20 grams of all drill cuttings samples in a well/wellbore. The samples are washed and dried on the rig.

 

Re Section 30
Final reporting of geo-technical and reservoir well data

The discovery evaluation report must be sent to the Norwegian Petroleum Directorate. A final geo-technical and reservoir-technical report, as well as the digital data mentioned in this provision shall be submitted to the Diskos database for all types of wells, along with reports on biostratigraphy, geochemistry and other special studies. 

All well depths shall be stated in relation to the drill floor/rotary table (RKB) and the logs shall be stated in measured depth (MD) and true vertical depth (TVD). Include information that makes it possible to convert from measured depth to vertical depth, as well as the geometry of the wellbore.
