A Comprehensive Study of Gas Migration Phenomenon in Oil and Gas Wellbores

EasyChair Preprint 10509

Abstract

Gas migration in wellbores is a critical concern in the oil and gas industry, leading to operational and safety issues. It occurs due to pressure differentials and permeable pathways. Detecting gas migration is vital to prevent hazards like blowouts. Monitoring methods include pressure monitoring, gas chromatography, and acoustic measurements. Preventive measures involve well design, effective casing, and cementing practices to minimize migration pathways. Wellbore integrity modeling and risk assessment tools aid in identifying potential scenarios. Operational procedures, safety protocols, and regular inspections are crucial for mitigation. Gas migration in wellbores poses significant challenges, requiring understanding, detection, and effective mitigation strategies. Advancements in technology and industry practices are necessary for minimizing and mitigating gas migration impacts in wellbores. To mitigate gas migration, several preventive measures can be implemented. Proper well design and construction techniques, such as effective casing and cementing practices, can minimize gas migration pathways. The use of wellbore integrity modeling and risk assessment tools can aid in identifying potential gas migration scenarios. Additionally, the implementation of robust operational procedures and safety protocols, along with regular inspections and maintenance, is crucial to mitigate the risks associated with gas migration.
