Gas infrastructure - Underground gas storage - Part 1: Functional recommendations for storage in aquifers
This European Standard covers the functional recommendations for design, construction, testing, commissioning, operation, maintenance and abandonment of underground gas storage (UGS) facilities in aquifers up to and including the wellhead.
It specifies practices, which are safe and environmentally acceptable.
For necessary surface facilities for underground gas storage, EN 1918-5 applies.
In this context "gas" is any hydrocarbon fuel:
- which is in a gaseous state at a temperature of 15 °C and under a pressure of 0,1 MPa (this includes natural gas, compressed natural gas (CNG) and liquefied petroleum gas (LPG). The stored product is also named fluid);
- which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfils contractual requirements.
This European Standard specifies common basic principles for underground gas storage facilities. Users of this European Standard should be aware that more detailed standards and/or codes of practice exist. A non-exhaustive list of relevant standards can be found in Annex A.
This European Standard is intended to be applied in association with these national standards and/or codes of practice and does not replace them.
In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of this European Standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts).
NOTE CEN/TR 13737 (all parts) contains:
- clarification of relevant legislation/regulations applicable in a country;
- if appropriate, more restrictive national requirements;
- national contact point for the latest information.
This European Standard is not intended to be applied retrospectively to existing facilities.
Gasinfrastruktur - Untertagespeicherung von Gas - Teil 1: Funktionale Empfehlungen für die Speicherung in Aquiferen
Diese Europäische Norm legt die funktionalen Empfehlungen für Planung, Errichtung, Prüfung, Inbetriebnahme, Betrieb, Instandhaltung und Stilllegung von Untertagegasspeicheranlagen in Aquiferen bis einschließlich des Bohrlochkopfes fest.
Sie legt sichere und umweltverträgliche Verfahrensweisen fest.
Für erforderliche Übertageanlagen für einen Untertagegasspeicher gilt EN 1918 5.
In diesem Zusammenhang ist „Gas“ jeder Brennstoff auf Kohlenwasserstoffbasis, der:
— sich bei einer Temperatur von 15 °C und unter einem Druck von 0,1 MPa in gasförmigem Zustand befindet (dazu gehören Erdgas, komprimiertes Erdgas (en: compressed natural gas, CNG) und Flüssig-gas (en: liquefied petroleum gas, LPG). Das gespeicherte Produkt wird auch als Medium bezeichnet);
— bestimmte Qualitätsanforderungen erfüllt, um die Integrität des Untertagespeichers, die Leistung und die Umweltverträglichkeit aufrechtzuerhalten, und vertragliche Anforderungen erfüllt.
Die vorliegende Europäische Norm legt allgemeine Grundsätze für Untertagegasspeicheranlagen fest. Die Anwender dieser Europäischen Norm sollten sich bewusst sein, dass detailliertere Normen und/oder Technische Regeln existieren. Eine Liste einschlägiger Normen, die allerdings nicht abschließend ist, findet sich in Anhang A.
Es ist vorgesehen, dass diese Europäische Norm in Verbindung mit nationalen Normen und/oder Technischen Regeln angewendet wird. Sie ersetzt diese nicht.
Beim Auftreten von Widersprüchen aufgrund restriktiverer Anforderungen in nationalen Gesetzen/Vor-schrif¬ten als in der vorliegenden Europäischen Norm gefordert haben nationale Gesetze/Vorschriften Vorrang, wie in CEN/TR 13737 (alle Teile) dargestellt.
ANMERKUNG CEN/TR 13737 (alle Teile) enthält:
— Darstellung der in den einzelnen Ländern zu beachtenden Gesetze/Vorschriften;
— wenn notwendig, darin enthaltene restriktivere nationale Anforderungen;
— eine nationale Kontaktstelle für die aktuellsten Informationen.
Es ist nicht vorgesehen, diese Europäische Norm rückwirkend auf bestehende Anlagen anzuwenden.
Infrastructures gazières - Stockage souterrain de gaz - Partie 1 : Recommandations fonctionnelles pour le stockage en nappe aquifère
La présente Norme européenne décrit les recommandations fonctionnelles pour la conception, la construction, les essais, la mise en service, l'exploitation, la maintenance et l'abandon des stockages souterrains de gaz en nappes aquifères jusqu'à la tête de puits incluse.
Elle spécifie les pratiques acceptables pour la sécurité et l'environnement.
Pour les installations de surface qui sont nécessaires pour un stockage souterrain de gaz, l'EN 1918-5 s’applique.
Dans ce contexte, le terme « gaz » désigne tout combustible hydrocarboné :
— qui est à l'état gazeux à une température de 15 °C et sous une pression de 0,1 MPa (sont inclus le gaz naturel, le gaz naturel comprimé (GNC) et le gaz de pétrole liquéfié (GPL)). Le produit stocké est également appelé « fluide » ;
— qui satisfait à des prescriptions spécifiques en matière de qualité afin de maintenir l'intégrité, les performances, la compatibilité environnementale du stockage souterrain et qui respecte les prescriptions contractuelles.
La présente Norme européenne spécifie les principes communs fondamentaux des stockages souterrains de gaz. Il convient que les utilisateurs de la présente Norme européenne gardent à l'esprit qu'il existe des normes et/ou des codes de bonne pratique plus détaillés. Une liste non exhaustive des normes pertinentes figure à l'Annexe A.
La présente Norme européenne est destinée à s'appliquer conjointement avec ces normes nationales et/ou codes de bonne pratique ; elle ne les remplace pas.
En cas de conflits en termes de prescriptions plus restrictives dans la réglementations/législation nationale vis-à-vis des prescriptions de la présente Norme européenne, la réglementation/législation nationale prévaut comme illustré dans le CEN/TR 13737 (toutes les parties).
NOTE Le CEN/TR 13737 (toutes les parties) donne :
— la clarification des législations/règlements applicables dans un pays ;
— si approprié, des prescriptions nationales plus restrictives ;
— un point de contact national pour une information ultérieure.
La présente Norme européenne n'est pas prévue pour être appliquée de façon rétroactive aux installations existantes.
Infrastruktura za plin - Podzemna plinska skladišča - 1. del: Funkcionalna priporočila za skladiščenje v vodonosnikih
Ta standard zajema funkcionalna priporočila za načrtovanje, izgradnjo, preskušanje, delovanje, vzdrževanje in opustitev podzemnih plinskih skladišč v vodonosnikih, vključno z ustjem vrtine. Določa prakse, ki so varne in okoljsko sprejemljive. Potrebni nadzemni objekti za podzemno skladiščenje plina so opisani v standardu prEN 1918-5. »Plin« v tem kontekstu pomeni vsako ogljikovodikovo gorivo, ki je v plinastem stanju pri temperaturi 15 °C in tlaku 1 bar. To vključuje zemeljski plin (imenovan tudi CNG) in LPG.

Key 1 operating wells 2 monitoring wells 3 indicator horizon 4 caprock 5 storage reservoir and stored gas 6 salt dome 7 cavern Figure 1 — Storage in aquifers, oil and gas fields, solution mined salt caverns For LPG storage only salt or rock caverns can be applied. The UGS type applied, is dependent on the geological conditions and prerequisites as well as on the designed capacity layout. 4.2.3 General characterization of UGS UGS are naturally or artificially developed reservoirs respectively artificially developed caverns in subsurface geological formations used for the storage of natural gas (or LPG). An UGS consists of all subsurface and surface facilities required for the storage and for the withdrawal and injection of natural gas (or storage of LPG). Several subsurface storage reservoirs or caverns may be connected to one or several common surface facilities. The suitability of subsurface geological formations have to be investigated individually for each location, in order to operate the storage facilities in an efficient, safe and environmentally compatible manner. In order to construct a storage facility wells are used to establish a controlled connection between the reservoir or cavern and the surface facilities at the well head. The wells used for cycling the storage gas are called operating wells. In addition to the operating wells, specially assigned observation wells may be used to monitor the storage performance with respect to pressures and saturations and the quality of reservoir water as well as to monitor any interference in adjacent formations.

This presupposes: — adequate prior knowledge of the geological formation, in which the storage is to be developed and of its geological environment; — acquisition of all relevant information needed for specifying parameter limits for construction and operation; — demonstration that the storage is capable of ensuring long-term containment of the stored gas through its hydraulic and mechanical integrity.
