Natural gas and oil reserves on the Dutch territory; national accounts

Dataset is not available.

This table contains the physical data on natural gas and oil reserves that are derived from the annual publication Natural resources and geothermal energy in the Netherlands by TNO commissioned by the Ministry of Economic Affairs. In 2018, there was a substantial downward adjustment of the gas reserves in the Groningen gas field.

The reserves consist of (socially responsible and commercially viable) extractable quantities of natural gas and oil found in the Netherlands, plus the amount pending development. The opening stock of the reserves is 1 January and the closing stock is 31 December. Definitions and data are in accordance with the Petroleum Resource Management System which has been used by TNO since 2013.
For reasons of consistency with Dutch terminology, we have opted to use reserves rather than resources as used in the TNO report.

Data available from: 1987

Description topics

Oil reserves
The reserves consist of the amount of oil in the Netherlands which has been discovered and considered extractable (socially responsible and commercially viable), increased by the amount in gas fields pending development.
Opening stock
The opening stock consists of the amount of reserves as of 1 January of the reporting year. The opening stock is equal to the closing stock of the previous year.
New discoveries
Newly discovered oil accumulations on the Dutch territory.
Oil accumulation: a natural, isolated accumulation of oil in a subsurface reservoir consisting of a porous rock that is capped or enclosed by an impermeable rock.
Extraction and other changes
Consists of the extraction of oil (at the expense of the reserve). In addition, the reserves are adjusted because of re-evaluation of estimates of existing reserves as a result of technical changes (e.g. new technologies), from the point of view of social responsibility (safety and feelings of security among the population) and/or changes in economic conditions (different market circumstances).
Closing stock
The closing stock consists of the amount of reserves as of 31 December of the reporting year. The closing stock is the opening stock of the next year.
