Material Selection Strategy for Corrosion Control in Iranian Upstream Oil and Gas Industry

Annually, a huge amount of money is lost due to corrosion problems in upstream and downstream oil and gas industries. To control the corrosion costs, recently, corrosion control/corrosion management concept is developed. The aim of corrosion management philosophy is to reduce corrosion costs and increase safety by re-evaluation process in different stages of the project. The material selection process is one of the key stages in integration assurance of the system, which plays important role in the overall corrosion control process. Some important parameters in selecting suitable materials for use in a given working and environmental condition includes design pressure and temperature, weldability, costs and corrosion concerns. Nowadays, the last one attracted the attention of the both researchers and owners. Codes like ISO 21457 necessitate providing Material Selection Procedure Report before proceeding executive steps of the project. Without any specific material selection procedure; the material selection process will be a complex and confusing task because of the diversity in codes and fluid service conditions. This study aims to introduce researchers and engineering with corrosion concerns especially in CO2, H2S, and salt contained services and the solutions which are normally employed in the upstream oil industry to deal with associated problems. Towards, environmental deterioration problems the oil and gas fields of Iran are discussed and the related treatments are presented.
