Petroleum and natural gas industries - Well integrity - Part 1: Life cycle governance (ISO 16530-1:2017)
ISO 16530-1:2017 is applicable to all wells that are operated by the petroleum and natural gas industry. This document is applicable to any well, or group of wells, regardless of their age, location (including onshore, subsea and offshore wells) or type (e.g. naturally flowing, artificial lift, injection wells).
ISO 16530-1:2017 is intended to assist the petroleum and natural gas industry to effectively manage well integrity during the well life cycle by providing:
- minimum requirements to ensure management of well integrity; and
- recommendations and techniques that well operators can apply in a scalable manner based on a well's specific risk characteristics.
Assuring well integrity comprises two main building blocks: the first is to ensure well integrity during well design and construction, and the second is to manage well integrity throughout the remaining well life thereafter.
This document addresses each stage of the well life cycle, as defined by the six phases in a) to f), and describes the deliverables between each phase within a Well Integrity Management system.
a) The "Basis of Design Phase" identifies the probable safety and environmental exposure to surface and subsurface hazards and risks that can be encountered during the well life cycle. Once identified, these hazards and risks are assessed such that control methods of design and operation can be developed in subsequent phases of the well life cycle.
b) The "Design Phase" identifies the controls that are to be incorporated into the well design, such that appropriate barriers can be established to manage the identified safety and environmental hazards. The design addresses the expected, or forecasted, changes during the well life cycle and ensures that the required barriers in the well's design are based on risk exposure to people and the environment.
c) The "Construction Phase" defines the required or recommended elements to be constructed (including rework/repair) and verification tasks to be performed in order to achieve the intended design. It addresses any variations from the design which require a revalidation against the identified hazards and risks.
d) The "Operational Phase" defines the requirements or recommendations and methods for managing well integrity during operation.
e) The "Intervention Phase" (including work-over) defines the minimum requirements or recommendations for assessing well barriers prior to, and after, any well intervention that involves breaking the established well barrier containment system.
f) The "Abandonment Phase" defines the requirements or recommendations for permanently abandoning a well.
The six phases of the well life cycle, as defined in this Scope, and their interrelationships, are illustrated in Figure 1 in the Introduction.
ISO 16530-1:2017 is not applicable to well control. Well control refers to activities implemented to prevent or mitigate unintentional release of formation fluids from the well to its surroundings during drilling, completion, intervention and well abandonment operations, and involves dynamic elements, i.e. BOPs, mud pumps, mud systems, etc.
ISO 16530-1:2017 is not applicable to wellbore integrity, sometimes referred to as "borehole stability". Wellbore integrity is the capacity of the drilled open hole to maintain its shape and remain intact after having been drilled.
Erdöl- und Erdgasindustrie - Bohrungsintegrität - Teil 1: Lebenszykluslenkung (ISO 16530-1:2017)
Dieses Dokument gilt für alle durch die Erdöl- und Erdgasindustrie betriebenen Bohrungen. Dieses Dokument gilt für jede Bohrung oder Gruppe von Bohrungen, unabhängig von deren Alter, Lage (einschließlich Onshore-, Unterwasser- und Offshore-Bohrungen) oder Typ (z. B. Bohrungen mit natürlichem Zufluss, künstlichem Gaslift, Injektion).
Dieses Dokument ist vorgesehen zur Unterstützung der Erdöl- und Erdgasindustrie beim wirksamen Management der Integrität einer Bohrung während ihres Lebenszyklus durch Bereitstellung von:
— Mindestanforderungen für die Sicherstellung des Bohrungsintegritätsmanagements; und
— Empfehlungen und Verfahren, die der Bohrungsbetreiber auf anpassbare Weise anwenden kann, auf der Grundlage bohrungsspezifischer Risikomerkmale.
Die Sicherstellung der Bohrungsintegrität umfasst zwei Hauptbestandteile: erstens die Sicherstellung der Bohrungsintegrität während der Auslegung und Herstellung und zweitens im Anschluss daran das Management der Bohrungsintegrität während der gesamten verbleibenden Lebensdauer der Bohrung.
Dieses Dokument behandelt jede der nachstehend festgelegten sechs Phasen a) bis f) des Lebenszyklus einer Bohrung und beschreibt die zwischen den jeweiligen Phasen innerhalb eines Bohrungsintegritäts-managementsystems zu erbringenden Arbeitsergebnisse:
a) in der „Auslegungsgrundlagenphase“ werden die wahrscheinlichen Gefährdungen in Zusammenhang mit der Sicherheit und der Einwirkung von Umweltbedingungen Über- und Untertage festgestellt, die während des Lebenszyklus einer Bohrung auftreten können. Nach ihrer Feststellung werden diese Gefährdungen und Risiken analysiert, damit Kontrollverfahren für Auslegung und Betrieb in nachfolgenden Phasen des Lebenszyklus einer Bohrung entwickelt werden können;
b) in der „Auslegungsphase“ werden die Kontrollen festgelegt, die bereits bei der Auslegung der Bohrung zu berücksichtigen sind, um geeignete Barrieren zum Management der festgestellten Sicherheits- und Umweltrisiken vorsehen zu können. Bei der Auslegung werden die erwarteten oder vorhersehbaren Änderungen während des Lebenszyklus einer Bohrung berücksichtigt und sichergestellt, dass die erforderlichen Barrieren bereits bei der Auslegung der Bohrung auf das Risiko für Personen und Umwelt abgestimmt sind;
c) in der „Bohr- und Inbetriebnahmephase“ werden die die durchzuführenden Arbeitsschritte (einschließlich Nacharbeit/Reparatur) und durchzuführenden Verifizierungstätigkeiten festgelegt, die für das Erreichen der vorgesehenen Auslegung erforderlich sind oder empfohlen werden. Sie behandelt sämtliche Abweichungen von der Auslegung, die eine erneute Validierung hinsichtlich der identifizierten Gefährdungen und Risiken erfordern;
d) in der „Betriebsphase“ werden die Anforderungen oder Empfehlungen sowie Verfahren für das Bohrungsintegritätsmanagement während des Betriebs festgelegt;
e) in der „Interventionsphase“ (einschließlich Aufwältigung) werden die Mindestanforderungen oder Empfehlungen für die Bewertung der Bohrungsbarrieren vor und nach jeglicher Intervention festgelegt, die das geplante Öffnen des Barrieresystems berücksichtigt;
f) in der „Verfüllungsphase“ werden die Anforderungen oder Empfehlungen für den dauerhaften Verschluss einer Bohrung festgelegt.
Die in diesem Anwendungsbereich festgelegten sechs Phasen des Lebenszyklus einer Bohrung und deren wechselseitige Beziehungen sind in Bild 1 in der Einleitung dargestellt

Industrie du pétrole et du gaz naturel - Intégrité du puits - Partie 1 : Gouvernance du cycle de vie (ISO 16530-1:2017)
L'ISO 16530-1:2017 s'applique à tous les puits exploités par l'industrie du pétrole et du gaz naturel. Le présent document s'applique à tout puits ou groupe de puits, indépendamment de son âge, de sa localisation (y compris puits terrestre, sous-marin et en mer) ou de son type (par exemple: puits à écoulement naturel, en activation ou injection).
L'ISO 16530-1:2017 a pour objet d'aider l'industrie du pétrole et du gaz naturel à gérer efficacement l'intégrité du puits pendant son cycle de vie en fournissant:
- les exigences minimales auxquelles satisfaire pour assurer la gestion de l'intégrité du puits; et
- les recommandations et les techniques que les exploitants de puits peuvent appliquer de manière évolutive, en fonction des caractéristiques de risque spécifiques d'un puits.
L'assurance de l'intégrité du puits repose sur deux composantes principales: premièrement, assurer l'intégrité du puits pendant sa conception et sa construction et, deuxièmement, gérer par la suite l'intégrité du puits pendant sa durée de vie restante.
L'ISO 16530-1:2017 traite de chaque étape du cycle de vie du puits, telle que définie par les six phases a) à f), et décrit les livrables requis entre chaque phase dans le cadre d'un système de gestion de l'intégrité du puits:
a) La «Phase de base de conception» identifie les expositions probables, ayant une incidence sur la sécurité et l'environnement, aux phénomènes dangereux et risques en surface et subsurface pouvant être rencontrés pendant le cycle de vie du puits. Une fois identifiés, ces phénomènes dangereux et risques sont évalués de sorte que des méthodes de contrôle de la conception et de l'exploitation puissent être mises au point dans les phases suivantes du cycle de vie du puits.
b) La «Phase de conception» identifie les mesures de contrôle à intégrer à la conception du puits, de manière à pouvoir établir des barrières appropriées pour gérer les phénomènes dangereux identifiés relatifs à la sécurité et à l'environnement. La conception traite des changements attendus ou prévus pendant le cycle de vie du puits et assure que les barrières nécessaires dans la conception du puits sont basées sur l'exposition au risque des personnes et de l'environnement.
c) La «Phase de construction» définit les éléments qu'il est nécessaire ou recommandé de construire (y compris reprise/réparation) ainsi que les activités de vérification qu'il faut réaliser afin d'obtenir la conception désirée. Elle traite des changements dans la conception qui nécessitent une revalidation en fonction des phénomènes dangereux et risques identifiés.
d) La «Phase d'exploitation» définit les exigences ou recommandations et les méthodes concernant la gestion de l'intégrité du puits pendant son exploitation.
e) La «Phase d'intervention» (y compris reconditionnement) définit les exigences minimales ou les recommandations concernant l'évaluation des barrières du puits avant et après une intervention sur le puits nécessitant la rupture du système de confinement constitué par les barrières du puits.
f) La «Phase d'abandon» définit les exigences ou les recommandations relatives à l'abandon définitif d'un puits.
Les six phases du cycle de vie du puits, telles que définies dans le présent article «Domaine d'application», et leurs interrelations sont illustrées à la Figure 1de l'Introduction.

Industrija za predelavo nafte in zemeljskega plina - Celovitost vrtine - 1. del: Upravljanje življenjskega cikla (ISO 16530-1:2017)
Ta standard o celovitosti vrtine podaja navodila za industrijo za predelavo nafte in zemeljskega plina za učinkovito upravljanje celovitosti vrtine med delujočim stanjem vrtine. »Delujoče stanje vrtine« je opredeljeno kot življenjski cikel vrtine od predaje v fazi izgradnje do faze opustitve, kar zagotavlja skladnost z določeno ovojnico za varno obratovanje. Standard obravnava proces upravljanja celovitosti vrtine z identificiranimi vrstami vrtin glede na tveganje izpostavljenosti za ljudi, okolje, sredstva in ugled, podporo pa zagotavljajo povezani načrti vzdrževanja/nadzora, tehnični pregledi in upravljanje sprememb, kot je podrobno navedeno v naslednjih korakih:
1. Proaktivni proces spremljanja vrtine/pregleda na terenu za ovojnico za varno obratovanje vrtine, ki vključuje spremembe parametrov toka, sestave plina ali pretoka, tlaka vmesnih prostorov, korozije ali obrabe, kar zagotavlja, da vrtina obratuje varno v okviru svojih omejitev. Spremembe ovojnic za obratovanje je treba zabeležiti, povezano opravilo za zagotavljanje vzdrževanja in nadzora stanja vrtine pa je treba posodobiti.
2. Vrste vrtin, določene na podlagi okolja (na kopnem, na morju, pod morjem) in funkcionalnosti (injektor, proizvajalec, umetno dviganje, plin, nafta, voda) s podanimi ovojnicami za obratovanje ali pregradnimi elementi. Zahteve za pregradne elemente temeljijo na morebitnem tveganju za izliv vrtine in resnosti vpliva na okolje. Vrsta vrtine določa pogostost pregledov in vzdrževanja določenih pregrad, da se zmanjša tveganje za okolje, ljudi, sredstva in ugled.
3. Nadzor na podlagi tveganja in načrti vzdrževanja na podlagi vrste vrtine in izpostavljenosti tveganju, ki zagotavljajo, da se vrtine vzdržujejo v ovojnicah za varno obratovanje. Za zmanjšanje tveganja za nenadzorovano sproščanje ogljikovodikov ali povezanih proizvodov pri proizvodnih ali brizgalnih dejavnostih v okolje (ozračje/morje/močvirje/kopno ali vodonosniki) v življenjskem ciklu posamezne vrtine.

Overview
EN ISO 16530-1:2017 - "Petroleum and natural gas industries - Well integrity - Part 1: Life cycle governance" (ISO 16530-1:2017) sets out a governance framework for managing well integrity across the entire well life cycle. Applicable to all wells (onshore, offshore, subsea; production, injection or artificially lifted), the standard provides minimum requirements and scalable recommendations so operators can manage well integrity in proportion to the well’s risk profile. It explicitly excludes well control and borehole stability.
Key topics and technical requirements
- Well life cycle phases: Defines six lifecycle phases - Basis of Design, Design, Construction, Operational, Intervention (including work-over), and Abandonment - and the deliverables between phases.
- Well integrity management system (WIMS): Establishes a governance structure, roles and responsibilities, documentation, reporting and handover processes to ensure consistent integrity practices.
- Risk assessment and risk register: Requires identification, assessment and documentation of hazards and risks to develop appropriate control measures and a well-type risk profile.
- Barrier philosophy and verification: Describes barrier types (technical, operational, human, administrative, impact) and requires verification and testing (function tests, barrier verification tests, modelling as appropriate).
- Performance standards and operating limits: Specifies that equipment and operational limits must be defined, monitored and managed to maintain barrier integrity.
- Change control and assurance: Mandates Management of Change (MOC) procedures, dispensation processes, quality assurance/approval and continuous improvement mechanisms (KPIs, lessons learned).
- Auditing and documentation: Calls for regular auditing, comprehensive documentation of well integrity status and phase-specific deliverables.
Practical applications and users
Who uses EN ISO 16530-1:
- Operator companies establishing or improving a well integrity management system across portfolios.
- Well designers and drilling/completion engineers applying barrier-based design and risk controls.
- Field operations and asset teams responsible for operational limits, verification and interventions.
- Service companies and contractors performing construction, testing and interventions in compliance with the operator’s WIMS.
- Regulators and auditors assessing governance, documentation and compliance with industry best practice.
Practical uses:
- Creating or updating a fit-for-purpose WIMS for onshore, offshore or subsea wells.
- Defining phase deliverables and handover criteria between design, construction and operations teams.
- Structuring risk-based verification programmes and failure-mitigation strategies for existing wells.
- Standardising barrier verification, MOC and audit practices across multiple assets.
Related standards
- Use alongside other ISO/CEN and national standards for petroleum and natural gas operations, and with industry guidance on specific well life-cycle activities (design, completion, abandonment) to achieve comprehensive well integrity governance.
Keywords: ISO 16530-1, well integrity, life cycle governance, well life cycle, well integrity management system, well barriers, risk assessment, petroleum and natural gas.

記事のタイトル：EN ISO 16530-1:2017 - 石油および天然ガス産業 - ウェルの完全性 - パート1：ライフサイクルガバナンス（ISO 16530-1:2017） 記事の内容：ISO 16530-1:2017は、石油および天然ガス産業によって運営されているすべてのウェルに適用されます。この規格は、任意のウェルまたはウェルのグループに適用され、年齢、場所（陸上、水中、海上ウェルを含む）、またはタイプ（自然流入、人工揚水、注入井戸など）に関係なく適用されます。 ISO 16530-1:2017は、ウェルのライフサイクル全体でウェルの完全性を効果的に管理することを目指しており、ウェルの特定のリスク特性に基づいてウェルオペレータが適用できる、最小の要件と推奨事項と技術を提供します。 ウェルの完全性を確保するには、ウェルの設計および建設中にウェルの完全性を確保すること、およびその後のウェルの残りの寿命の間にウェルの完全性を管理することの2つの主要な構成要素があります。 この規格は、a）からf）で定義されるウェルのライフサイクルの各段階に取り組み、ウェル完全性管理システム内の各段階間の成果物について説明しています。 a）「設計基準段階」では、ウェルのライフサイクル中に遭遇する可能性のある地上および地下の危険およびリスクに対する予測される安全性および環境的露出を識別します。識別されたこれらの危険およびリスクは、ウェルのライフサイクルの後の段階で開発できる設計と操作の制御手法を評価します。 b）「設計段階」では、識別された安全および環境的リスクを管理するためにウェルデザインに組み込むべき制御を識別します。設計はウェルのライフサイクル中の予想される変化に対応し、ウェルの設計には人々と環境へのリスク曝露に基づいて必要なバリアが確立されます。 c）「建設段階」では、意図した設計を達成するために構築（修復/補修を含む）する必要のある要素または推奨要素および検証タスクを定義します。設計からの変更に対処し、識別された危険およびリスクとの再確認を必要とします。 d）「運用フェーズ」では、運用中のウェルの完全性を管理するための要件または推奨事項と方法を定義します。 e）「介入フェーズ」（ワークオーバーを含む）では、既存のウェルバリア封止システムを破壊するウェル介入の前および後にウェルバリアを評価するための最小要件または推奨事項を定義します。 f）「廃止フェーズ」では、ウェルを永久に廃止するための要件または推奨事項を定義します。 このスコープで定義されたウェルライフサイクルの6つのフェーズとその相互関係は、イントロダクションの図1に示されています。 ISO 16530-1:2017はウェル制御には適用されません。ウェル制御は、掘削、完成、介入、およびウェル廃止作業中に井戸から周囲への予期しない地層流体の放出を防止または軽減するために実施される活動を指し、BOP、泥ポンプ、泥システムなどの動的要素を含みます。 ISO 16530-1:2017はウェルボア完全性、またはしばしば「ボアホールの安定性」とも呼ばれるものにも適用されません。ウェルボア完全性とは、掘削された開口部が形状を維持し、掘削後も破損しない能力を指します。
The article discusses the EN ISO 16530-1:2017 standard, which applies to wells operated by the petroleum and natural gas industry. The standard aims to assist the industry in effectively managing well integrity throughout the entire life cycle of a well. It provides minimum requirements and recommendations for well operators to ensure well integrity based on specific risk characteristics. The article describes the six phases of the well life cycle, including the basis of design, design, construction, operational, intervention, and abandonment phases. However, the standard does not cover well control or wellbore integrity.
ISO 16530-1:2017は、石油および天然ガス産業で運用されるすべてのウェルに適用される文書です。この文書は、年齢、場所（陸上、海底、海上のウェルを含む）、タイプ（自然流動、人工リフト、注入ウェルなど）に関わらず、すべてのウェルまたはウェルグループに適用されます。 ISO 16530-1:2017は、ウェルのライフサイクル中におけるウェルインテグリティの効果的な管理を石油および天然ガス産業に支援することを目的としています。具体的には、ウェルインテグリティの管理を確保するための最小要件と、ウェルの特定のリスク特性に基づいてウェルオペレーターが適用できる推奨事項と技術を提供します。 ウェルインテグリティの確保には、ウェルの設計と建設時にウェルインテグリティを確保することと、以降のウェルの寿命中にウェルインテグリティを管理することの2つの主要な要素があります。 この文書では、a）からf）で定義される6つのフェーズによるウェルのライフサイクルの各ステージに対応し、ウェルインテグリティ管理システム内の各フェーズ間の成果物について説明しています。 - 「設計基盤フェーズ」では、ウェルのライフサイクル中に遭遇する可能性のある地表および地下のハザードとリスクによる安全性と環境への露出を特定します。特定されたハザードとリスクは、ウェルの後続フェーズの設計および運用のためにコントロール方法が開発されるように評価されます。 - 「設計フェーズ」では、安全および環境上のハザードを管理するためにウェル設計に組み込まれるコントロールを特定します。設計はウェルの寿命サイクル中の予想される変更に対応し、要求されるウェルのバリアは人々と環境へのリスク露出に基づいています。 - 「建設フェーズ」では、意図した設計を達成するために構築する必要または推奨される要素（再作業/修理を含む）や検証タスクを定義します。設計からの変更について、特定のハザードとリスクに対する再評価が必要な場合も取り扱います。 - 「運用フェーズ」は、運用中のウェルインテグリティを管理するための要件や推奨事項、方法を定義します。 - 「介入フェーズ」（ワークオーバーを含む）は、確立されたウェルバリア封じ込めシステムの破損が関与する場合に、介入前および後のウェルバリア評価のための最小要件や推奨事項を定義します。 - 「廃棄フェーズ」では、ウェルを永久に放棄するための要件や推奨事項を定義します。 この範囲で定義される6つのウェルライフサイクルのフェーズとその相互関係は、導入の図1で示されています。 ISO 16530-1:2017はウェルコントロールには適用されません。ウェルコントロールは、掘削、完了、介入、およびウェル廃棄作業中にウェルからその周囲への意図しない流体の放出を防止または軽減するために実施される活動であり、BOP、泥漿ポンプ、泥漿システムなどの動的要素が関与します。 ISO 16530-1:2017は、ウェルボアインテグリティ、または「穴穿孔の安定性」として言及されるウェルボアの形状と構造の保持能力には適用されません。
The article discusses ISO 16530-1:2017, a document that provides guidelines for managing well integrity in the petroleum and natural gas industry. It is applicable to all types of wells, regardless of their age, location, or design. The document focuses on ensuring well integrity throughout the well life cycle, which includes six phases: Basis of Design, Design, Construction, Operational, Intervention, and Abandonment. Each phase has specific requirements and recommendations for managing well integrity. The document also emphasizes the importance of identifying and assessing hazards and risks to establish appropriate barriers for safety and environmental protection. However, it is important to note that ISO 16530-1:2017 does not cover well control activities, which involve preventing unintentional fluid release, or wellbore integrity, which refers to maintaining the drilled hole's shape and structural integrity.
