Oil and gas industries including lower carbon energy - Production assurance and reliability management (ISO/DIS 20815:2025)
This document describes the concept of production assurance within the systems and operations associated with exploration drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. This document covers upstream (including subsea), midstream and downstream facilities, petrochemical and associated activities. It focuses on production assurance of oil and gas production, processing and associated activities and covers the analysis of reliability and maintenance of the components. This includes a variety of business categories and associated systems/equipment in the oil and gas value chain. Production assurance addresses not only hydrocarbon production, but also associated activities such as drilling, pipeline installation and subsea intervention.
This document provides processes and activities, requirements and guidelines for systematic management, effective planning, execution and use of production assurance and reliability technology. This is to achieve cost-effective solutions over the life cycle of an asset development project structured around the following main elements:
— production assurance management for optimum economy of the facility through all of its life cycle phases, while also considering constraints arising from health, safety, environment, and quality;
— planning, execution and implementation of reliability technology;
— application of reliability and maintenance data;
— reliability-based technology development, design and operational improvement.
The IEC 60300-3 series addresses equipment reliability and maintenance performance in general.
This document designates 12 processes, of which seven are defined as core production assurance processes and addressed in this document. The remaining five processes are denoted as interacting processes and are outside the scope of this document. The interaction of the core production assurance processes with these interacting processes, however, is within the scope of this document as the information flow to and from these latter processes is required to ensure that production assurance requirements can be fulfilled.
The only requirement mandated by this document is the establishment and execution of the production assurance programme (PAP). It is important to reflect the PAP in the overall project management in the project for which it applies.
This document recommends that the listed processes and activities be initiated only if they can be considered to add value.

Industries du pétrole, de la pétrochimie et du gaz naturel - Assurance production et gestion de la fiabilité (ISO/DIS 20815:2025)
Le présent document introduit le concept d'assurance production dans les systèmes et les opérations liés au forage, à l'exploitation, au traitement et au transport des ressources pétrolières, pétrochimiques et en gaz naturel. Le présent document couvre les installations et les activités amont (y compris sous-marines), intermédiaires et aval, la pétrochimie ainsi que les activités associées. Il est axé sur l'assurance production relative à la production du pétrole et du gaz, sur le traitement et les opérations associées et couvre l'analyse de la fiabilité et de la maintenance des composants. Cela comprend une variété de catégories d'activité et de systèmes/équipements associés au sein de la chaîne de valeur du gaz et du pétrole. L'assurance production concerne non seulement la production des hydrocarbures, mais également les activités associées telles que le forage, l'installation de conduites et les interventions sous-marines.
Le présent document fournit des processus et des activités, des exigences et des lignes directrices pour la gestion systématique, la planification, l'exécution et l'utilisation efficaces de l'assurance production et des techniques fiabilistes. Le but est d'obtenir des solutions rentables sur tout le cycle de vie d'un projet de développement d'une installation de production structurée autour des éléments principaux suivants:
— gestion de l'assurance production pour une économie optimale de l'installation durant toutes les phases de son cycle de vie, tout en tenant compte des contraintes résultant de facteurs liés à la santé, à la sécurité, à l'environnement et à la qualité;
— planification, exécution et mise en œuvre des techniques fiabilistes;
— application des données de fiabilité et de maintenance;
— amélioration du développement, de la conception et de l'exploitation de technologies basées sur la fiabilité.
La série IEC 60300-3 a trait à la fiabilité des équipements et à l'exécution de la maintenance.
Le présent document définit douze processus, dont sept sont définis comme des processus fondamentaux de l'assurance production et sont abordés dans le présent document. Les cinq processus restants sont appelés processus en interaction et ne relèvent pas du domaine d'application du présent document. L'interaction des processus fondamentaux de l'assurance production avec ces processus interactifs s'inscrit toutefois dans le domaine d'application du présent document car le flux d'informations à destination et en provenance de ces derniers processus est requis pour s'assurer que les exigences de l'assurance production peuvent être remplies.
La seule exigence spécifiée par le présent document concerne l'établissement et l'exécution du programme d'assurance production (PAP). Il est important que le PAP se reflète dans la gestion globale du projet auquel il s'applique.
Le présent document recommande de ne lancer les processus et activités qu'il énumère que s'ils peuvent apporter de la valeur ajoutée.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that

Introduction
The oil and gas industries including petrochemical and lower carbon energy activities involve large capital
expenditure (CAPEX) as well as operating expenditure (OPEX). The safety and the profitability of the
associated assets are dependent upon the reliability, availability and maintainability of the systems and
components that are used. Therefore, for optimal production availability to deliver affordable energy in a
sustainable manner, standardized and integrated production assurance and reliability management are
essential.
The concept of production assurance, introduced in this document, enables a common understanding with
respect to use of reliability technology in the various life cycle phases and covers the activities implemented
to achieve and maintain a performance level that is at its optimum in terms of the overall economy and, at
the same time, consistent with applicable regulatory requirements and framework conditions.
