Overview
EN ISO 17824:2014 (ISO 17824:2009) specifies requirements and guidelines for sand control screens used as downhole equipment in the petroleum and natural gas industries. The standard covers design, design validation, functional evaluation, manufacturing, storage and transport for three main sand screen types: wire‑wrap screens, pre‑pack screens, and metal‑mesh screens. It was prepared by ISO/TC 67 and adopted by CEN to provide a common baseline for suppliers and purchasers of sand screens.
Key Topics and Requirements
- Scope and exclusions: Applies to wire‑wrap, pre‑pack and metal‑mesh sand screens. Excludes expandable sand screens, slotted liners/tubing, accessory items (e.g., centralizers), shunt screen technology, inflow control devices, downhole sensors, selective isolation devices, screen filtration performance criteria, and basepipe end connections.
- Functional specification: Defines product types, sand screen and well parameters, operational and environmental compatibility, and compatibility with related well equipment.
- Design and validation: Establishes design criteria, verification and validation processes. The standard provides three design validation grades (V1, V2, V3) to match application criticality.
- Quality control: Sets supplier/manufacturer requirements, documentation, product identification, and three quality grades (Q1, Q2, Q3) to scale inspection and QA levels.
- Mechanical testing: Normative annexes include collapse and burst test methods (Annex A and B). Informative annexes provide measurement methods, illustrations of screen types and inspection guidance (Annexes C–H).
- Manufacturing, storage and transport: Specifies minimum practices for production, marking, protection, handling and shipping to preserve integrity of downhole equipment.
Applications
- Specifying sand screen requirements in procurement and tender documents for well completions and remediation.
- Guiding manufacturers on design verification, mechanical testing and quality management to demonstrate conformity.
- Assisting well designers and completion engineers in selecting appropriate sand control screens for reservoir and wellbore conditions.
- Defining minimum storage, handling and transport practices to protect downhole equipment before deployment.
Who uses this standard
- Oil & gas operators and completion engineers
- Sand screen manufacturers and suppliers
- Procurement teams and specification writers
- Testing and inspection laboratories
- Subsea and well‑services contractors
