Abstract
An experimental study was made to understand the role of lecithin in hydrate formation/stabilization in drilling fluids. The effect of lecithin on the thermodynamics and kinetics of methane hydrate formation/decomposition in pure water was investigated. Experimental results indicated that lecithin did not significantly affect the hydrate thermodynamic equilibrium conditions. Lecithin was however an excellent kinetics promoter as indicated by a significant increase in the rates and amounts of hydrate formation when the concentration of lecithin was over 0.003 g·g-1.
