Effect of LDHI-AAs on Hydrate-in-Oil Suspensions

Visual observations of hydrate aggregation, deposition and surface morphology using a dynamic flowloop are presented both with and without the addition of an anti-agglomerant (AA). An in-line camera provides high quality video images of the fluid and hydrate particles during experiments. A straight pipe viscometer with high resolution differential pressure gauges at different fixed lengths was used to investigate the relative fluid viscosity with and without the addition of an AA at various hydrate volume fractions. With the addition of an AA, the fluid viscosity decreased and can lead to improved transportability of the fluid and ultimately increase hydrocarbon production.
