MOSCOW, Aug 25 (Reuters) - Urals crude differentials to dated Brent in northwest Europe lost another 15 cents a barrel on Friday to hit the lowest level since May 31 after a provisional loading plan for Baltic ports and Novorossiisk showed ample supplies.

* In the Platts window, Glencore offered a 100,000-tonne cargo of Urals for loading from Primorsk or Ust-Luga on Sept. 7-11 at minus $1.35 a barrel to dated Brent, but found no interest, traders said.
* Vitol offered a similar cargo for Sept. 6-10 down to minus $1.00 a barrel.
* Urals ex-Baltic Sea ports was assessed at minus $1.25 a barrel on Thursday.
