Paper presented at the SPE Offshore Europe Conference and Exhibition, September 3–6, 2019
Paper Number: SPE-195704-MS
... the overall preservation sequence, crude abilities to delay hydrates formation and/or to transport hydrates have been studied on the coldest fields. It was found that studied crudes present interesting properties to delay hydrates formation. These tests have been performed with crude samples in lab conditions...

.... The conventional graphical method backed up with visual observation have been employed for dissociation point determination. Equipment Abstract Produced waters, due to the presence of salts, have a hydrate inhibiting effect. However, the data on hydrate formation in the presence of electrolytes is scarce...

..., cold water environments. When hydrates form in production streams, they can pose problems with economic consequences. Field experience indicates that hydrates occasionally obstruct production flowpaths (Ref 1 and 2 ). In the event of a partial obstruction, hydrate formation is a nuisance, slowing...
