The formation of non-agglomerating hydrate slurries has been reported by several laboratories.  Pumpable hydrate slurries have been generated successfully in re-circulating loops.  However, a slow hydrate film growth mechanism prevented sustained slurry flow in a recent field trial.  This paper reports the observations of hydrate film formation in a once-through 3/8-inch lab apparatus and its relationship to observations in a once-through 4-inch field facility.  The origin of this film formation will be discussed.
