Abstract

The growth and aggregation potential of gas hydrates in subsea flowlines are critical risk parameters for oil and gas production flow assurance. Hydrate interfaces may be exposed to water and hydrocarbon phases where natural oil surfactants may have a tendency to adsorb. The cohesion and growth between cyclopentane hydrate (structure II hydrate) particles exposed to natural oil surfactants in modified hydrocarbon phases were studied using a micromechanical force (MMF) apparatus. An Australian crude oil (unmodified), isolated asphaltenes and resins obtained via SARA fractionation and, when added to the cyclopentane phase, reduced the hydrate cohesive force by up to 98% (
