ISO 20815:2018

Overview

ISO 20815:2018 - Petroleum, petrochemical and natural gas industries - Production assurance and reliability management - defines a system-level approach to production assurance and reliability management across upstream (including subsea), midstream and downstream facilities. The standard explains processes, activities, requirements and guidelines for planning, executing and applying reliability technology and maintenance data to achieve cost‑effective life‑cycle performance for oil, gas and petrochemical assets. The only mandatory requirement is establishing and executing a production assurance programme (PAP), which should be integrated into overall project management.

Key topics and technical requirements

• Production assurance concept: framework for maintaining optimal production availability while considering HSEQ constraints (health, safety, environment, quality).
• Lifecycle focus: guidance covers exploration, drilling, production, processing, transport, subsea intervention, and associated petrochemical activities.
• Reliability and maintenance analysis: application of reliability engineering and maintenance planning to components and systems to improve availability and reduce cost.
• Processes: the standard identifies 12 processes (7 core production assurance processes addressed in the document and 5 interacting processes). Interaction and information flow between core and interacting processes is within scope.
• Production Assurance Programme (PAP): required deliverable - defines objectives, risk categorization, and programme activities; recommended to be value‑added and reflected in project management.
• Data and metrics: use of reliability and maintenance data for performance measurement, planning and technology development (see normative reference ISO 14224:2016 for data collection).
• Alignment with other guidance: acknowledges IEC 60300‑3 series for general equipment reliability and references related ISO technical reports.

Practical applications and users

Who uses ISO 20815:2018:

• Asset and operations managers seeking to optimize availability and lifecycle costs
• Reliability and maintenance engineers implementing condition‑based and preventive maintenance
• Project managers integrating PAP into project execution and risk management
• Design engineers applying reliability inputs to equipment and system design
• Consultants, regulators and owners evaluating production performance and assurance processes

Typical applications:

• Designing a PAP for a new field development or brownfield upgrade
• Structuring reliability‑based maintenance strategies for processing plants or pipelines
• Integrating reliability data into performance KPIs and decision support
• Aligning subsea and drilling activities with production assurance objectives
