EN ISO 17078-1:2004 PDF

Overview

EN ISO 17078-1:2004 (ISO 17078-1:2004) specifies requirements for side-pocket mandrels used in the petroleum and natural gas industries. Adopted by CEN as a European Standard, this part covers the specification, selection, design, manufacture, quality control, testing and preparation for shipping of side‑pocket mandrels used in drilling and production equipment. It defines minimum supplier/manufacturer obligations and a framework of grades and service classes to match product performance to application needs.

Note: this part does not cover end connections to well conduit, installation/retrieval operations, centre‑set mandrels, tubing‑retrievable devices, or the valves/latches/wireline equipment that may be covered in other ISO documents.

Key topics and technical requirements

• Functional and technical specifications - functional characteristics, well and operational parameters, compatibility with related downhole devices.
• Design criteria and validation - design verification, allowable design changes and validation grades to establish performance assurance.
• Quality control and testing - defined quality‑control grades, product‑functional testing grades, and corresponding inspection/testing requirements (including NDE).
• Environmental service classes - four service classes to select materials and corrosion/cracking resistance for H2S and other downhole conditions.
• Supplier/manufacturer requirements - documentation, data control, product identification, heat treatment, welding, non‑destructive examination (NDE), storage, shipping preparation and repair controls.
• Normative references - related standards cited include ISO 9000 (quality management), ISO 11960 (casing/tubing steel pipes), ISO 15156 (materials for H2S environments), and metallic testing standards (hardness, tensile).

Practical applications and who uses this standard

• Manufacturers and suppliers of side‑pocket mandrels use ISO 17078-1 to design and certify products that meet established industry minimums.
• Oil & gas operators and well engineers use it to specify mandrels that are compatible with well conditions and downhole equipment.
• Procurement and quality assurance teams rely on the standard to assess vendor conformity, testing regimes, traceability and shipping requirements.
• Regulators and certifiers may reference it when reviewing equipment suitability for field deployment, especially in corrosive or H2S‑containing environments.

Related standards

• ISO 17078 series (other parts under development: gas‑lift/flow control devices, latches/seals/interface data)
• ISO 9000 (Quality management)
• ISO 11960 (Casing and tubing steel pipes)
• ISO 15156 (Materials for H2S environments)
• ISO metallic testing standards (Brinell, Rockwell, tensile)

ISO 17078-1 is a practical reference for ensuring side‑pocket mandrels are designed, manufactured and tested to consistent, auditable industry practices for reliable downhole service.
