Phase Equilibrium of Methane Hydrates in the Presence of MgBr₂, CaBr₂, and ZnBr₂ Aqueous Solutions

Hydrate formation in natural gas transportation pipelines and during completion and workover operations is considered to be a serious issue. CaBr2 and ZnBr2 salts are widely used to design high-density completion fluids for completion of oil and gas wells; however, information on the hydrate phase equilibria in the presence of these salts is missing. In this study, a three-phase liquid water–hydrate–vapor (L-H-V) equilibrium conditions for...
