NACE 1D177

Abstract

<strong>Foreword</strong> <br>This NACE state-of-the-art report includes descriptions of monitoring techniques and corrosion control programs that have been used on drilling rigs in many different regions of the world. Field information from tests evaluating corrosion control of drill pipe, casing, and steel components in contact with various drilling fluids is incorporated and presented. Corrosion inhibition programs have provided increased life for equipment ranging from the fluid ends of mud pumps to the steel drill pipe and casing. Workover operation personnel have become more aware of the need to treat completion and workover fluids to mitigate corrosion. These treatments have resulted in fewer metal failures and have provided safer operations for drilling and completion of wells. This report does not cover air and gas drilling techniques or thermal recovery projects. <br>The intended audience for this report is drilling, workover, and completion operations. This technical committee report was originally prepared in 1977 by Task Group T-1D-17, a component of Unit Committee T-1D, "Corrosion Monitoring and Control of Corrosion Environments in Petroleum Production Operations." It was reaffirmed in 1995 by T-1D and was revised in 2009 by Task Group (TG) 376, "Monitoring Techniques for the Control of Corrosion of Drill Pipe, Casing, and Other Steel Components in Contact with Drilling Fluids." TG 376 is administered by Specific Technology Group (STG) 31, "Oil and Gas Production&#226;&#8364;&#8221;Corrosion and Scale Inhibition" and is sponsored by STG 62, "Corrosion Monitoring and Measurement: Science and Engineering Applications." This report is issued by NACE International under the auspices of STG 31.
