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 document 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).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 67, Oil and gas industries including lower carbon energy, Subcommittee SC 4, Drilling, production and injection equipment, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 12, Oil and gas industries including lower carbon energy, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 17078-2:2007), which has been technically revised. It also incorporates the Technical Corrigendum ISO 17078-2:2007/Cor 1:2009.

The main changes are as follows:

the document was fully reorganized;
definition, description, design optimization and requirements related to tubing-retrievable flow-control devices have been added to the document;
ISO 16530-1 and ISO 7-1 have been added to the Bibliography.

A list of all parts in the ISO 17078 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html.

Introduction

This document supplements API Spec 19G2, 2nd edition (2020).

The technical requirements of this document and API Spec 19G2 used to be identical. In the meantime, API Spec 19G2 has been technically revised as API Spec 19G2, 2nd edition (2020). The purpose of this edition of ISO 17078-2 is to bring it up to date, by referencing the current edition of API Spec 19G2 and including supplementary content.

1 Scope

This document provides requirements for subsurface flow-control devices used in side-pocket mandrels intended for use in the worldwide petroleum and natural gas industry. This document addresses injection-pressure-operated (IPO), production-pressure-operated (PPO), pilot, orifice, tubing-retrievable, and dummy flow-control devices. It includes requirements for selecting, designing, manufacturing, quality control, testing, and preparation for the shipping of flow-control devices. Additionally, it includes information regarding performance testing and calibration requirements.

The installation and retrieval of flow-control devices is outside the scope of this document. Additionally, this document is not applicable to flow-control devices with concentric axes.

This document does not include requirements for side-pocket mandrels, running, pulling, kick-over tools, or latches. Reconditioning of used flow-control devices is outside the scope of this document.

This document supplements API Spec 19G2, 2nd edition (2020), the requirements of which are applicable with the exceptions specified in this document.
