LONDON, March 19 (Reuters) - North Sea Forties crude
differentials weakened on Friday after a deal, while Brent was
steady.
PLATTS WINDOW
* Indications are on a free on board (FOB) basis unless
marked as cost, insurance and freight (CIF).
* Forties: Shell sold to Trafigura a CIF Rotterdam April 5-9
cargo at dated Brent plus 75 cents, down 25 cents from a similar
offer on Thursday. On a FOB basis, according to Reuters
calculations, this equates to dated Brent parity.
* Brent: Vitol offered and later withdrew a CIF Rotterdam
cargo for March 31-April 6 at dated Brent plus $1.20, the same
level as an offer on Thursday.
