Abstract
This paper investigates the significance of bentonite prehydration in oil well cement formulations and its impact on cementing operations. Through laboratory experiments and field case studies, the study aims to enhance cement properties, improve slurry stability, and optimize wellbore integrity. Laboratory experiments analyzed various prehydration methods' effects on cement slurry properties like fluid loss, rheology, and compressive strength. Field case studies assessed real-world applications and practical benefits. Comparative analysis of prehydration techniques such as batch and continuous mixing was conducted, providing comprehensive insights into bentonite prehydration's necessity and efficacy in cementing job success. Findings revealed that bentonite prehydration significantly improved cement slurries' rheological properties, enhancing fluidity and pumpability while reducing fluid loss, thereby stabilizing wellbores. Prehydrated bentonite slurries exhibited higher compressive strength, indicating improved cement quality and bonding. Field case studies reinforced prehydration's importance by reducing gas migration and lost circulation issues during cementing operations, enhancing zonal isolation and cementing job success. The study underscores the critical role of bentonite prehydration in oil and gas cementing operations, offering practical solutions to address various challenges encountered in cementing jobs.
