Overview

kSIST FprEN ISO 17078-2:2026 specifies the requirements for subsurface flow-control devices intended for use in side-pocket mandrels in the global oil, gas, and lower carbon energy sectors. These devices are crucial for managing flow within wells, enhancing safety and operational efficiency in drilling, production, and fluid injection processes.

The standard addresses a wide range of flow-control device types, including injection-pressure-operated (IPO), production-pressure-operated (PPO), pilot, orifice, tubing-retrievable, and dummy devices. It provides criteria for selecting, designing, manufacturing, testing, and preparing these devices for shipment, ensuring product reliability and alignment with international best practices. Installation and retrieval operations, as well as concentric-axis devices, are not covered.

This document supplements API Spec 19G2 and harmonizes with the latest industry requirements, enabling interoperability and quality assurance across the petroleum and natural gas equipment supply chain.

Key Topics

• Device Types

  • Injection-pressure-operated (IPO)
  • Production-pressure-operated (PPO)
  • Pilot and orifice flow-control devices
  • Tubing-retrievable flow-control devices
  • Dummy devices for pressure isolation

• Scope of Requirements

  • Selection and specification of flow-control devices for side-pocket mandrels
  • Design and manufacturing quality assurance
  • Performance testing and device functional validation
  • Calibration and preparation for shipment

Applications

The requirements set out in kSIST FprEN ISO 17078-2:2026 are intended to ensure safe, reliable, and efficient deployment of flow-control devices in subsurface environments such as:

• Oil and Gas Wells
  Used for injection, production control, and pressure management in various wellbore configurations.

• Gas Lift Operations
  Controlling gas injection to optimize production in mature wells.

• Enhanced Oil Recovery (EOR) and Water Injection
  Facilitating precise fluid management in secondary and tertiary recovery operations.

• Lower Carbon Energy Projects
  Supporting subsurface flow management in wells utilized for CO₂ injection or storage, consistent with the industry's movement toward decarbonization.

The standard promotes equipment compatibility, product interchangeability, and lifecycle reliability, yielding operational efficiencies and risk reduction in drilling and production environments.

Related Standards

For comprehensive flow-control system management, consider these closely associated international standards:

• ISO 17078-1: Drilling and production equipment - Side-pocket mandrels
• ISO 17078-3: Running tools, pulling tools, and kick-over tools for side-pocket mandrels
• ISO 17078-4: Practices for side-pocket mandrels and related equipment
• ISO 9000: Quality management systems - Fundamentals and vocabulary
• ISO 7-1: Pipe threads where pressure-tight joints are made on the threads
• API Spec 19G2: Flow-control devices for side-pocket mandrels

These references, along with the guidelines in kSIST FprEN ISO 17078-2:2026, help operators, manufacturers, and service providers achieve compliance and optimal equipment performance within the international oil, gas, and evolving lower carbon energy industries.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of

This document was prepared by Technical Committee [or Project Committee] ISO/TC [or ISO/PC] 67,
Subcommittee SC4.
This second edition cancels and replaces the first edition (ISO 17078-2:2009), which has been technically
revised.
This document supplements API [SPECIFICATION 19G2], 2nd edition (2020).
The technical requirements of this document and API [SPECIFICATION 19G2] used to be identical. In the
meantime API [SPECIFICATION 19G2-2010] has been technically revised as API [SPECIFICATION 19G2], 2nd
edition (2020). The purpose of this edition of ISO 17078-2[2024]is to bring it up to date, by referencing the
current edition of API [SPECIFICATION 19G2-2020 and including supplementary content.
The main changes compared to the previous edition are as follows:
— Tubing-retrievable flow-control devices were added into the Scope.
— ISO 9000, ISO 17078-1, ISO 17078-3, ISO 17078-4 and ISO 7-1 were added in 2 Normative references and
API Q1, API 19G1, API 19G3 and API 19G4 deleted.
— The definition of tubing-retrievable flow-control devices was added in 3 Terms and definitions.
— The description of tubing-retrievable flow-control devices was added in Table 1, 6 Technical specification.
— The design optimization of tubing-retrievable flow-control devices was added in 6.3.9 Good design
practice.
— The requirements for testing of tubing-retrievable flow-control devices were added in Annex C.
