LONDON, Nov 18 (Reuters) - Differentials for the North Sea
Brent crude oil stream jumped to their highest since December
2019 and Forties hit a four-month high on Thursday on the back
of higher bids by Vitol amid strike threats for platforms
feeding the grades.
* The Unite Union this week announced a possible strike from
December to February impacting offshore fields operated by
TotalEnergies, some of which contribute to the Forties and Brent
Blend crude oil streams.
* On Oct. 21 Unite said about 100 workers on platforms
linked to the North Sea Ninian crude oil field, which feeds into
the global Brent benchmark, were set for intermittant
strike days between Nov. 5 and Dec. 4 over a wage dispute. The
dispute was resolved before industrial action took place, with
Unite members accepting an improved offer from Petrofac,
a Unite spokesman said.
