3330 Guidelines for the materials selection and corrosion management of downhole production and injection well equipment

Overview:

This document is intended to provide guidance on the methodology and issues that need consideration in the management of corrosion for downhole applications. The focus is on conventional oil and gas production wells and injection wells although there are some comments on other well-types.

Guidance provided in this document will be of use to duty holders, managers of operations, engineering and maintenance functions and as an introduction for those requiring a basic understanding of the subject. By use of this Guideline it is hoped that critical issues and options will not get overlooked, leading to a safer and more cost-effective management of the corrosion challenges of well equipment.

It is however not intended to provide a prescriptive guide to materials and corrosion mitigation choices for specific conditions. There are other resources available that offer such advice and individual company philosophies may vary. Furthermore, there may be many valid approaches to corrosion management. This document aims to present a high level of consideration, alerting the user to the breadth of factors which can play a part in getting the correct answer for any specific project and circumstance.
