Methods for Testing of Solid and Rigid Centralizers - First Edition
 N TR 10TR5

Annotation

Introduction

Solid and rigid centralizers have been used by the petroleum industry for many years to assist with running casing to the bottom of the wellbore and with improving mud displacement. The purpose of this document is to provide the industry with methods for testing rigid and solid centralizers.

The API and ISO standardization committees have produced specifications, testing, and recommended practices for the use of bow-type centralizers, but to date, the petroleum industry does not have standards for the selection and use of solid or rigid centralizers, even though those devices are widely used. Additionally, the industry does not have standardized testing methods to verify functionality and reliability of centralizers. This is a problem for the operator in making an intelligent selection for centralizers to use in the well. Some testing procedures are available, but because they are not standardized, they tend to hinder communication between manufacturers and end users.
