Sept 16 (Reuters) - The discount on Western Canada

Select (WCS) heavy crude versus the North American benchmark

West Texas Intermediate (WTI) tightened on Monday:

* WCS for October delivery in Hardisty, Alberta, settled at

$13.50 a barrel below WTI, according to brokerage CalRock,

having settled at $13.75 a barrel under the benchmark on Friday.

* Canadian heavy crude prices continue to trade in the

narrow range between $13.50 and $14.00 a barrel below benchmark

U.S. crude that they have been in all month.

* Global oil prices rose as the ongoing impact of Hurricane

Francine on output in the U.S. Gulf of Mexico offset persistent

Chinese demand concerns ahead of this week's U.S. Federal

Reserve interest rate cut decision.
