Phase equilibrium study of methane hydrate
Gas hydrates are solid metastable ice like compounds formed when gas comes in contact with water and have the ability to form at low temperatures. In this study, methane gas hydrates were formed in a Berea sandstone core, which was saturated with brine and then pressurized with methane gas. The form...
