Overview
EN ISO 10417:2004 - "Petroleum and natural gas industries - Subsurface safety valve systems - Design, installation, operation and redress (ISO 10417:2004)" is a sector standard published by CEN that establishes requirements and provides guidelines for subsurface safety valve (SSSV) systems and associated downhole production equipment. The standard covers configuration, installation, testing, operation and documentation of SSSV systems, and addresses selection, handling, redress and documentation of SSSV downhole production equipment. EN ISO 10417:2004 (also published as EN ISO 10417:2005 in some national catalogs) is not applicable to repair activities - see ISO 10432 for SSSV repair requirements.
Key Topics and Requirements
- Scope and applicability: Requirements and guidance for subsurface safety valve (SSSV) systems used in petroleum and natural gas wells; covers downhole production equipment selection and handling.
- Design and configuration: Principles for SSSV system configuration to meet safety and operability objectives (system layout, functional roles).
- Installation requirements: Best-practice guidance for downhole installation procedures, positioning and integration of SSSVs with well completion equipment.
- Testing and commissioning: Procedures for pre-installation and post-installation testing, functional verification and acceptance testing.
- Operation and maintenance: Operational checks, monitoring practices and documented operating procedures for SSSV systems.
- Redress and handling: Guidelines for redress (refurbishment and reconditioning) and safe handling of downhole SSSV equipment prior to redeployment.
- Documentation and traceability: Required records, test reports, maintenance logs and traceability information to demonstrate compliance and support ongoing well integrity management.
- Limitations: Specifies that repair activities are excluded - repair is covered by ISO 10432.
Applications and Who Uses This Standard
- Oil and gas operators and production engineers specifying and commissioning SSSV systems for well safety and emergency isolation.
- Well integrity and completion engineers developing design and installation procedures.
- Service companies and equipment vendors responsible for supply, handling, redress and testing of downhole safety valves.
- Project managers, HSE professionals and regulators requiring standardized documentation and testing to support safety management and regulatory compliance.
- Inspection and commissioning teams performing acceptance testing and validation of subsurface safety systems.
Benefits
- Improves well safety by standardizing SSSV selection, installation and operation.
- Facilitates consistent documentation and traceability for compliance and asset management.
- Supports reliable emergency shutdown capability in production wells.
