Operational Strategies for Enhancing Injectivity and Protecting Against Corrosion in Gas Injection Wells in Hassi Messaoud field

Abstract

This work presents the main operational interventions aimed at improving injectivity and protecting injection wells from corrosion. Efficient fluid injection into the reservoir is essential for maximizing production. Operational strategies to enhance injectivity include: cleaning interventions, matrix acidizing, and hydraulic fracturing. Strategies to protect wells from corrosion include: detecting aggressiveness factors and installing impressed current systems for electrochemical corrosion. These protective measures reduce corrosion risks, ensuring safe and reliable operation of injection wells while extending their lifespan in the Hassi Messaoud field.
