Background:• Formation of hydrates in sub-sea Production Riser completely stopped production • Attempts over a four month period to re-establish production were unsuccessful• Pre job modelling confirmed friction reducers necessary due to difficult saddle back profile with inclinations of up to 165 deg .Objectives:NOV Solutions • Remove hydrates without having to retrieve or replace the riser• Minimise CT tripping inside flexible riserons Showcase Method:• Pump ethylene glycol to remove hydrates• Use Andergauge AG-itator as method of friction reduction to getCT to hydrate plugNOV SolutionsResults:All objectives achieved in one run• Hydrates removed re-establishing production• Job made possible with the AG-itator through extremelylow friction factors (down to 0.14 -0.16)ons
