Overview

SIST EN ISO 17078-2:2026 is a key standard for the oil and gas industries including lower carbon energy, focusing on drilling, production and injection equipment. It specifies requirements for flow-control devices for side-pocket mandrels used in the worldwide petroleum and natural gas industry.

This standard is especially relevant for organizations working with subsurface flow-control devices, including:

• Injection-pressure-operated (IPO) devices
• Production-pressure-operated (PPO) devices
• Pilot devices
• Orifice devices
• Tubing-retrievable devices
• Dummy devices

It provides practical guidance for the selection, design, manufacturing, quality control, testing, calibration, and shipping preparation of flow-control devices. For operators and manufacturers, the standard supports consistent product performance, safer engineering practices, and better alignment with international oil and gas requirements.

Importantly, this document is a supplement to API Spec 19G2, 2nd edition (2020), with specified exceptions and updates. It is a valuable reference for companies seeking to maintain compliance with recognized industry expectations for side-pocket mandrel flow-control devices.

Key Topics

The standard addresses several core technical and quality-focused areas:

• Scope of flow-control device requirements for side-pocket mandrels
• Design and manufacturing requirements for subsurface equipment
• Quality control and testing expectations
• Performance testing and calibration information
• Preparation for shipping of flow-control devices
• Validation and functional testing considerations

It also clarifies what is outside the scope, including:

• Installation and retrieval of flow-control devices
• Devices with concentric axes
• Side-pocket mandrels themselves
• Running, pulling, kick-over tools, and latches
• Reconditioning of used flow-control devices

The document is structured to support engineering teams and procurement specialists who need a clear standard for flow-control device specification in petroleum and natural gas operations.

Applications

SIST EN ISO 17078-2:2026 is applicable across a range of upstream oil and gas activities where controlled fluid flow is required in side-pocket mandrel systems. Typical practical uses include:

• Well completion and production system design
• Gas lift and injection-related equipment selection
• Quality assurance for manufactured flow-control devices
• Supplier qualification and product conformity checks
• Testing programs for device performance and calibration

For asset owners and service companies, the standard helps improve reliability, interoperability, and documentation quality. It is also useful for teams managing international projects that require consistent petroleum equipment standards.

Related Standards

This standard is closely linked with several other normative references and companion documents in the ISO 17078 series:

• ISO 17078-1 - Side-pocket mandrels
• ISO 17078-3 - Running tools, pulling tools and kick-over tools and latches
• ISO 17078-4 - Practices for side-pocket mandrels and related equipment
• ISO 9000 - Quality management systems fundamentals and vocabulary
• ISO 7-1 - Pipe threads for pressure-tight joints
• API Spec 19G2 - Flow-control devices for side-pocket mandrels

Together, these standards support a broader framework for oil and gas drilling and production equipment, making SIST EN ISO 17078-2:2026 an important reference for compliant and efficient field operations.
