Abstract
Effective cementing plays a pivotal role in ensuring the integrity of oil and gas wells, providing mechanical support, fluid containment, and environmental protection. This paper presents guidelines for conducting wellbore cementing remediation processes effectively, emphasizing longevity while minimizing environmental impact and safeguarding groundwater. The discussion encompasses factors influencing successful remedial cementing, including cement slurry properties, pumping methods, and squeeze equipment. Common techniques such as squeeze cementing and perforation/plug back operations are examined in detail, highlighting their challenges, considerations, and cost implications. Moreover, technological advancements such as polymer gels, silica gels, and self-healing cements are explored for their potential in addressing persistent challenges in sustaining casing pressure and ensuring cement sheath integrity. Through a comprehensive examination of remedial cementing practices and innovations, this paper offers valuable insights for industry professionals striving to optimize well integrity and operational efficiency while mitigating risks and ensuring environmental responsibility.
