The object of the annual statistics for oil and gas activity is to provide an economic overview of the activity on the Norwegian continental shelf, as well as related service activity. Separate data collection for the oil and gas industries has been carried out since 1984. The oil statistics are used as basis for calculations in the National Account and for research purposes. The oil statistics provides principal figures like gross value of production, value added, intermediate consumption and more.

Statistics are part of the business statistics in SSB. The statistics will provide an overview of structure of industry 06 Extraction of crude petroleum and natural gas, 09.1 Support activities for petroleum and natural gas and 49.5 Pipeline.

National accounts, Eurostat, ministeries, branch associations and research. The needs of the nasional accounts and Eurostat/Fats regarding the extraction and pipeline industries are diverging. The national statistics, which are described here, are compiled according to the needs of the national accounts, while the figures reported to Eurostat and Fats are based on the same administrative sources as the rest of the business statistics.

No external users have access to the statistics and analyses before they are published and accessible simultaneously for all users on ssb.no at 8 am. Prior to this, a minimum of three months' advance notice is given inthe Statistics Release Calendar. (About engelsk versjon av likebehandlingsprinsippet)

National accounts

The statistics on extraction and related services build on data reported from a.o. the oil and gas industries and the Norwegian Petroleum Directorate. Statistics Norway publishes similar figures in the quarterly national accounts. Before the annual oil and gas statistics are published, the national account figures build on projections. These preliminary national account figures may deviate from the annual oil and gas statistics:

• Expenditure on research and development (private investment), and net expenses for banking services (FISIM) and insurance are included in intermediate consumption in the national accounts but not in oil statistics.

• Produced volume of natural gas is based on various sources, to ensure that national accounts are consistent with other important stats in SSB. The sources are checked against each other to ensure that any differences are small.

• The price of crude oil is based on various sources, to ensure that national accounts are consistent with other important stats in SSB. They are checked against each other to ensure that any differences are small. Previously, the prices of natural gas and condensate, based on various sources. From 2014 the gas prices are based on same source .

• In national accounts balance extraction industry towards access and use in other industries.

• Value added (market price) of oil statistics equals gross product (market) in the national accounts, but with the differences shown in the above. (It will not be published gross product at factor cost in the national accounts and value added to the base price of oil statistics.)

Before Annual statistics on extraction and related services are published and incorporated in the national accounts, the figures in the national accounts based on forecast from the previous year.

External trade statistics

The external trade statistics (ETS) publishes the export value of crude oil, natural gas, condensate and NGL-products. The value is estimated at the national border, while in the oil and gas statistics the value is estimated at the site of production. Furthermore, the oil and gas statistics cover production for the Norwegian market. From 2014, the annual statistics on extraction and related services based on gas prices from ETS.

Employment

Employment figures are also published in the national accounts, in employment statistics based on A-ordningen. The employment figures are annual averages and cover full-time and part-time employees.

The Statistics Act 21st of June 2019 number 32, §10 and §20

Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 on European business statistics (EBS)

The numbers are published according to the Norwegian industry classification (SIC2007) .

The classification is in accordance with the EU’s new NACE Rev. 2 classification. This enables comparability across country borders.

The annual statistics for oil and gas activity covers the folllowing 3 industries:

06: Extraction of crude oil and natural gas

09.10: Service activities incidental to oil and gas extraction

49.500: Transport via pipelines

All enterprises within 06, 09.10 and 49.500 are included in the statistics if they are registered with active operations in Norway in statistical year. (See also Data Sources and selection)

EU structural business Regulation primarily requires statistics on enterprise level. For reasons of national accounts and other Norwegian users, however, it compiled statistics on business unit level, ie. fields, terminals, pipelines and land office.

06 Extraction of crude oil and natural gas and 49.500: Transport via pipelines

The population covers all approved operators and license owners on the Norwegian continental shelf, including fields, terminals and offices, in addition to businesses in NACE 49.500 and pipelines registered as separate units in the business register. The data collection is a census, and the population is based on information from the Norwegian Petroleum Directorate (NPD) and the Ministery of Petroleum and Energy (MPE) in addition to central principles for population management.

Data on produced amounts from NPD are combined with price data from several sources to estimate the production value. For crude oil norm prices from MPE are used. Starting in 2012, used prices from external trade statistics for the three gas products, with the exception of 2013 where price data from the Oil Taxation Office (OTO) was used. Use of different data sources is to get the closest accurate prices.

From 2015 received tariff revenues for pipeline transport and environmental taxes from the NPD.

From license-owners, operators and pipeline-owners obtained data of operational costs and characteristic income for both extraction industry and pipeline, through a survey. From Gassco obtained tariff costs for Gassled (ie major pipelines, as well as two terminals).

Data of investment obtained from Investments in oil and gas, manufacturing, mining and electricity supply

09.10: Service activities incidental to oil and gas extraction

All enterprises with either employees, turn-over or investments are covered in the population. All multi-business enterprises, and all single-business enterprisees with more than 1 million NOK in revenue and above 20 employees are included in the sample. For single-business enterprises below 20 employees, a stratified sample is drawn. Data for enterprises outside the sample are based on administrative sources and distributions from the sample.

Sources include data from the Business statistics and administrative sources (tax statements, annual reports and the A-ordningen). The population in the business register is based on automatical updates from the Register of Business Enterprises in Brønnøysund, and maintained by means of the VAT register, information from branch organisations and dialogue with the enterprises.

The statistics use one survey form (RA 0756) for obtaining information from enterprises that belongs to 06 and 49.5.

Furthermore, the form for pipeline tariff is replaced by Revised National budget (RNB) data obtained from the NPD, and the former form for gas prices replaced by data from ETS, from 2014.

Both forms are only available in electronical form, and from 2015, the forms must submit through Altinn.no.

A series of quality controls are performed:

• Change from the previoius year on both micro and macro level.
• Consistency checks within and between forms.
• Consistency with other data sources:
• a) employment against register-based figures
• b) income and expenditure figures against tax statements and annual reports

06 Extraction of crude oil and natural gas and 49.500: Transport via pipelines

Operational costs and certain types of income are estimated based on reporting from the enterprises. The major part of the income is estimated from the net production volumes (NPD), prices (MPE and ETS), Gassled transport and terminal tariffs (Gassco AS), and RNB tariffs for those pipelines which are not included in Gassled. Internal trade within the industry is excluded.

09.10: Service activities incidental to oil and gas extraction

The totals are estimated based on information from the forms and the administrative sources. Geographical distribution is obtained from the form reporting, where the enterprises split certain incomes and costs on the single businesses.

Not relevant

Employees of Statistics Norway have a duty of confidentiality.

Statistics Norway does not publish figures if there is a risk of the respondent’s contribution being identified. This means that, as a general rule, figures are not published if fewer than three units form the basis of a cell in a table or if the contribution of one or two respondents constitutes a very large part of the cell total.

Statistics Norway can make exceptions to the general rule if deemed necessary to meet the requirements of the EEA agreement, if the respondent is a public authority, if the respondent has consented to this, or when the information disclosed is openly accessible to the public.

More information can be found on Statistics Norway’s website under Methods in official statistics, in the ‘Confidentiality’ section.

The following events have affected the time consistency:

2008/2009

For extraction industry (SN2007: 06) are employment figures from 2008 are not directly comparable with previous years. This is due to changes in the data of the implementation of employment register data. The employment figures in 2008 were revised upwards.

For service industry (SN2007: 09.10) has until the end of 2008 made a cut-off, where enterprises with fewer than 50 million in sales and fewer than 3 employees are excluded from the statistics. From 2009, the statistics are based on a complete census of all active enterprises in the industry. (See Source Data and selection).

From the 2009 vintage were 9 major companies reclassified from industrial enterprises of nourishment 09.10 Services to oil and natural gas.

2012

There were changes in method which have significant effect on the extraction industry from 2012, particular for calculation of the production value and intermediate consumption. Changes in method are requests which required from the national accounts. The major changes include:

• Deliveries between onshore and offshore within the industry regarded as internal deliveries and netted from 2012 (Until 2011, these deliveries treated as gross).

• New price data for natural gas, condensate and NGL. From 2012 price data from ETS, with the exception of 2013 when price data from OSK was used.

The following table summarizes the effect of changes in the figures for 2012.
Table: The effect of methode changes in 2012:

2013

In 2013, several enterprises were reclassified from other industries to the oil service industry. This contributed to the growth in the industry from 2012 to 2013. The reclassifications reflect an altered assessment of the firms' main activity, not a change in the activity itself.

2015

Restructuring of form survey for extraction industry contributed to the decline in estimated intermediate consumption and a corresponding increase in value added. These are the changes observed:

• Transport and processing tariffs at fields were sometimes reported as 'other transport and communication' for 2014, intermediate consumption was overestimated. The final figures for 2014 have been revised for this, and are consistent with 2015 figures at this point.

• R & D, taxes and fees except environmental taxes, are considered operating expenses of oil companies, but not by SSB. In the former survey was such costs reported as part of operating costs, while in the new study, these costs are excluded. This over reporting amounted to about 1-3 billion in 2014.

• The companies' investment in acquired technical services within seismology, geology, field evaluation, R & D and more, were counted as part of intermediate consumption until 2014. Since these are considered as investments, they are excluded from 2015. In 2014 these investments amounted to 5 billion NOK.

• Company own investments, as rent, electricity, office equipment, travel, fees and other administrative expenses were included in the intermediate consumption until 2014, but the preliminary figures for 2015, this kind of private investment only partially been included. The estimate was between 0-2 billion NOK, which is not included in the intermediate consumption in 2015, thereby providing a method-change effect on intermediate consumption and value added compared with 2014.

Overall, the decline in intermediate consumption of 6-10 billion and a corresponding increase in value added from 2014 to 2015 which is caused by the transition to the survey form. However, it can not be excluded pure survey form effects, resulting from changes in question formulation, new organization of data fields and new lay-out.

From statistical year 2014, the calculation of production value is based on gas prices from ETS. This provides a better consistency between the statistics and national accounts. The final figures of production value and value added for 2014 was revised upwards 17.7 billion NOK, as a result of this change.

2016

New calculation of intermediate consumption: From 2016, Operating and Other Insurance includes in calculation of intermediate consumption for the extraction industry. The change of calculation method is in accordance with Eurostat's definition of intermediate consumption. Insurance premium in 2016 was NOK 2.1 billion, which amounted to approx. 4 percent of the overall intermediate consumption.

The results of a statistical survey will usually contain certain collection and processing errors. There may also be uncertainty about the delimitation of the population, and that sample surveys contain sampling errors.

Collection errors may have occurred due to misunderstanding of questions in the form, use of unfamiliar terms, etc. The most common errors in extraction and pipeline transport until 2014 due to misunderstandings surrounding which survey form the information should be reported on, and thus a risk of gaps and double counting, and which information should be reported in this survey or in the quarterly investment statistics. From 2015 uses only one survey form for the company to fill out all their business units. The new survey form used more recognizable terms that the respondents are familiar with the contents, and clarifies the differences between this survey and the investment survey. Thus, the risk for errors should be reduced.

Editing errors occur such as the transmission of information from the questionnaire through editing base and computational programs to the final tables, or miscalculations during editing of raw data.

A series of editing controls are performed on both micro and macro scale (see 'Collection of data, editing and estimations'), where the largest errors are identified. Recently, a comprehensive editing of the production and estimation procedures was made (see 'Comparability over time and space'), during which several calculation errors were corrected.

Sampling uncertainty is not relevant for NACE 06 and 49.5, as the survey for these industries was a census with 100 per cent response rate. In NACE 09.10　a slight sampling uncertainty must be assumed. However, most data are collected from administrative sources covering the entire population.

Selection Uncertainty caused by the gathering of information is done on the basis of a sample selection of the population and not whole population, and that the response is not always 100 percent. For the statistic year 2015 was the response rate 100 percent for 06 Extraction of crude petroleum and natural gas and 49.5 Pipeline. Since this is also a full count, there was no sampling error in this industry. In 09.1 Extraction-related service industry, the response rate of sample survey was about 95 percent. However, most of the information obtained from administrative sources, where the entire population is covered. Therefore, selection error in 09.1 also very small.

NACE 09.10 is an industry with quite many enterprises doing different activities. There are frequent changes because of acquisitions and fusion. Hence, uncertainty in defining the population and coding the enterprises and businesses into correct industry is a source of error in this industry.

As of 2021, preliminary prices from external trade has been used to measure the production value of natural gas, condensate and NGL. This will lead to some uncertainty regarding the preliminary production numbers. Final figures will be adjusted with the use of final prices which gets published june the following year.
