In gas hydrate formation

The thermodynamic and structural processes that occur when water molecules are in the vicinity of hydrophobic entities (water fearing, insoluble in water) are referred to collectively as hydrophobic hydration (Tanford, 1973 Privalov and Gill, 1988 Blokzijl andEngberts, 1993 Chau and Mancera, 1999). Hydrophobic hydration is important in gas hydrate formation, which usually starts with hydrophobic gas molecules (e.g., methane) being introduced into liquid water.

Time-domain dielectric specfroscopy (TDS) may be used to follow hydrate formation in emulsified systems, and by means of this technique the role fliat different fractions of the crude play in gas hydrate formation in water-in-crude oil emulsions may be investigated (6,7).
