Full title and description

ISO 20815:2018 — Petroleum, petrochemical and natural gas industries — Production assurance and reliability management. This International Standard specifies principles, processes and requirements for production assurance and reliability management across upstream, midstream and downstream activities in the oil, gas and petrochemical value chain.

Abstract

ISO 20815:2018 describes the concept of production assurance within systems and operations associated with exploration, drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. It defines a production assurance programme (PAP), identifies production-assurance and reliability-management processes (12 processes in total, seven designated as core), and provides requirements and guidance for planning, execution and use of reliability and maintenance technologies to achieve cost‑effective lifecycle solutions while considering health, safety, environment and quality. The standard references related reliability guidance such as the IEC 60300‑3 series.

Scope

The standard applies to production assurance and reliability management for oil, gas and petrochemical operations across upstream (including subsea), midstream and downstream facilities and activities. It covers establishment and execution of a production assurance programme (PAP), reliability and maintenance analysis of components and systems, and the information flows between production assurance and interacting business processes required to meet production‑assurance objectives throughout an asset’s life cycle.

Key topics and requirements

• Establishment and execution of a Production Assurance Programme (PAP) — the single mandatory requirement of the standard.
• Definition of 12 production‑assurance processes, with seven identified as core processes to be addressed within the PAP.
• Lifecycle‑oriented production assurance: design, construction, operation, maintenance and decommissioning considerations.
• Reliability technology planning, execution and implementation; use of reliability and maintenance data to drive improvement.
• Reliability‑based design and operational improvement, and integration with HSE and quality constraints.
• Interaction with related processes and standards (information exchange and interfacing requirements).
• Reference to equipment‑reliability guidance such as IEC 60300‑3 for maintenance and reliability practices.

Key topics summarized from the ISO standard text.

Typical use and users

Used by oil & gas and petrochemical companies (asset owners and operators), engineering, procurement and construction (EPC) contractors, reliability and maintenance engineers, project and asset managers, integrity/operations teams, technical consultants, and regulators to establish, structure and implement production assurance activities and reliability programmes across projects and operating assets.

Related standards

ISO 20815:2008 (withdrawn; replaced by the 2018 edition), the IEC 60300‑3 series (equipment reliability and maintenance guidance) and other ISO/TC 67 publications on oil, gas and petrochemical industry practices. ISO has an FDIS in development to update/replace ISO 20815, listed as ISO/FDIS 20815.

FAQ

Q: What is this standard?

A: An ISO International Standard that defines production assurance and reliability‑management principles, processes and requirements for petroleum, petrochemical and natural gas industries (ISO 20815:2018).

Q: What does it cover?

A: It covers production assurance across upstream, midstream and downstream activities, specifying the production assurance programme (PAP), core and interacting processes, reliability and maintenance practices, and lifecycle‑based requirements and guidance for cost‑effective asset delivery and operation.

Q: Who typically uses it?

A: Asset owners/operators in oil, gas and petrochemical sectors, EPC contractors, reliability/maintenance engineers, project and asset managers, consultants and regulators who need to plan and implement structured production assurance and reliability activities.

Q: Is it current or superseded?

A: ISO 20815:2018 is the current published edition (Edition 2, October 2018) and was reviewed and confirmed by ISO in 2024. ISO is developing ISO/FDIS 20815 (an updated/replaced text) which is at FDIS stage; stakeholders should check the ISO catalogue for the latest status before relying on it for procurement or compliance.

Q: Is it part of a series?

A: It is maintained by ISO/TC 67 (petroleum, petrochemical and natural gas industries) and relates to other TC 67 publications and external reliability standards such as IEC 60300‑3. The standard itself sits within the body of industry standards for asset integrity, reliability and lifecycle management.

Q: What are the key keywords?
