Natural gas hydrate–related disasters and case studies

Clathrate hydrates, which develop at low temperatures and high pressures, are known as gas hydrates. Resources for natural gas hydrates are dispersed around the globe and have stayed steady for millions of years. Permafrost and coastal or marine reservoirs both contain these resources. Cages of water that capture small gas molecules like CH₄, C₂H₆, and C₃H₈ give rise to gas hydrates. Notably, gas hydrate plugs and their dissociation have significant negative effects on flowline operations in terms of safety and cost. We may recommend economic risk management to prevent hydrate formation based on prior research on employing thermodynamic and kinetic inhibitors to prevent hydrate plugs from developing. This chapter goes into great depth about these safety concerns. Moreover, seven case studies related to hydrate disasters and preventions are studied in this chapter. The mentioned field case studies varied from Siberia, the Gulf of Mexico, and also the Dog Lake fields.
