ISO 14310:2008

Overview - ISO 14310:2008 for packers and bridge plugs

ISO 14310:2008 specifies requirements and guidelines for downhole equipment-packers and bridge plugs-used in the petroleum and natural gas industries. The standard addresses functional and technical specifications including design, design verification and validation, materials, documentation and data control, repair, shipment, and storage. Products covered apply only to applications within a conduit (casing, tubing or liner). Installation and maintenance are outside the scope.

Key topics and requirements

• Definitions & scope: Clear definitions for terms such as packer, bridge plug, packing element, retrievable/repositionable/permanent devices, drift diameter, extrusion gap and performance envelope.
• Functional specification: Type description, well and operational parameters, environmental compatibility and compatibility with related well equipment.
• Design requirements: Engineering design criteria, material selection (including NACE/ISO 15156 compatibility for H2S environments), end connections and component classification (type 1/type 2).
• Design verification & validation: Procedures for verification and graded design validation (seven grades V6 to V0). V6 is the minimum where supplier-defined validation applies; complexity increases toward V0.
• Quality grades: Three quality grades (Q3 minimum, Q2 intermediate, Q1 highest) allowing purchaser-driven quality control and inspection levels.
• Manufacturing & supplier obligations: Documentation, data control, product identification, traceability (heat/job-lot traceable), non-conformance handling and assembly verification.
• Testing & performance: Requirements include performance envelope representation (differential pressure vs axial load), pressure reversal considerations, and validation by testing or scaled methods.
• Logistics: Requirements for repair, shipment and storage to maintain product integrity.

Practical applications - who uses ISO 14310:2008

• Downhole tool manufacturers - to design, validate, document and produce compliant packers and bridge plugs.
• Operators and service companies - to specify procurement, acceptance testing and quality requirements for downhole isolation tools.
• Procurement / quality assurance teams - to set inspection levels (AQL), traceability and supplier documentation expectations.
• Design and reliability engineers - to evaluate performance envelopes, material compatibility (including ISO 15156/NACE service) and risk of pressure reversal/extrusion.

Related standards

• ISO 11960 - steel casing and tubing
• ISO 15156 - materials for H2S-containing environments
• ISO 2859-1 - sampling procedures (AQL)
• ISO 3601 (O-rings) and ISO 9000 (quality management)
• ISO 9712 - NDT personnel qualification

ISO 14310:2008 helps align manufacturer practices and purchaser expectations for reliable downhole isolation tools, enabling consistent specification, testing and traceability in petroleum and natural gas operations.
