BERLIN, Nov 15 (Reuters) - Austria's OMV has

been informed by Gazprom that the Russian gas producer

would reduce its deliveries of natural gas from to zero from

0500 GMT on Nov. 16, according to information published on the

CEGH Remit platform on Friday.

The volume of natural gas affected amounts to up to 7,400

MWh/h, according to the notification.

Gazprom declined to comment.

Russian gas supply to oil and gas company OMV was at

risk of stopping

before the end of the year

due to an arbitration case against Gazprom, the company

warned yesterday.
