Full title and description

ISO 13679:2019 — Petroleum and natural gas industries — Procedures for testing casing and tubing connections. This international standard specifies standardized physical test procedures to determine galling tendency, sealing performance and structural integrity of casing and tubing connections used in oil and gas wells.

Abstract

This document describes tests to be performed on casing and tubing connections for commonly encountered well conditions (not all possible service scenarios are included). It addresses galling tendency, sealing performance and structural integrity, and it serves as a supplement to API RP 5C5:2017, with the API requirements being applicable except where this ISO standard specifies exceptions.

General information

• Status: Published.
• Publication date: 2019-07 (Second edition, 2019).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 75.200; 75.180.10 (petroleum and natural gas industry equipment and drilling/extraction equipment).
• Edition / version: Edition 2 (2019).
• Number of pages: 4 (ISO published document pagination).

Scope

Specifies procedures for testing connections used for casing and tubing to assess their performance under typical well service conditions. The standard focuses on tests for galling, sealing and structural integrity and does not attempt to cover every possible service scenario (for example, the specific effects of corrosive fluids are not addressed). It is intended to supplement API RP 5C5:2017 where applicable.

Key topics and requirements

• Standardized tests to determine galling tendency of connections under make-up and service conditions.
• Sealing performance tests to verify pressure-tightness of connections.
• Structural integrity tests (axial, bending and combined load conditions relevant to typical well environments).
• Classification of test severity intended to reflect commonly encountered well conditions (not exhaustive for all scenarios).
• Supplementary relationship to API RP 5C5:2017 — API requirements apply except where ISO 13679:2019 specifies otherwise.

Typical use and users

Used by connection designers and manufacturers, independent testing laboratories, well integrity and completion engineers, oil and gas operators, certification bodies and regulators to verify and document the mechanical and sealing performance of casing and tubing connections prior to field deployment.

Related standards

Directly related to API RP 5C5 (connection testing practice) — ISO 13679:2019 is intended to supplement that document. The 2019 edition replaces ISO 13679:2002. The document is also published/adopted as EN ISO 13679:2019 in the European system. It sits within the ISO/TC 67 portfolio of oil and gas industry standards.

FAQ

Q: What is this standard?

A: ISO 13679:2019 is an international standard that defines procedures to test casing and tubing connections for galling, sealing and structural integrity in typical well service conditions.

Q: What does it cover?

A: It covers standardized physical tests and related acceptance considerations for casing and tubing connections used in petroleum and natural gas wells, focusing on the most commonly encountered well conditions and supplementing API RP 5C5:2017. It does not cover every possible service scenario (for example, specific corrosive-fluid effects).

Q: Who typically uses it?

A: Manufacturers of connections, test laboratories, completion and well integrity engineers, operators, certification bodies and regulators use this standard for design verification and qualification testing of connections.

Q: Is it current or superseded?

A: ISO 13679:2019 is the current edition (second edition, published July 2019) and replaced ISO 13679:2002. The ISO publication record shows the 2019 edition as published and confirmed in subsequent review cycles.

Q: Is it part of a series?

A: It is part of the ISO/TC 67 body of standards for petroleum and natural gas industries and relates to other connection, tubular goods and well-construction standards (for example, those referenced by or supplementing API documents and other ISO/TC 67 publications).

Q: What are the key keywords?

A: Casing, tubing, connections, testing, galling, sealing, structural integrity, well conditions, API RP 5C5.
