UPDATE 1-OPEC seeks consensus on duration of oil cut pact before meeting

(Adds quote, details)

VIENNA, Nov 7 (Reuters) - OPEC is seeking to achieve consensus agreement before a meeting on Nov. 30 on how long to extend a global pact to curb oil production, OPEC's secretary general said on Tuesday.

The Organization of the Petroleum Exporting Countries, plus Russia and nine other producers, are cutting oil output by about 1.8 million barrels per day (bpd) until March 2018 in an effort to eradicate a supply glut that has weighed on prices.

The deal has supported prices, which are trading at a more than two-year high, but an overhang of stored oil has yet to be fully eradicated and producers are considering extending the deal at the Nov. 30 meeting.

"Extensive consultations are currently ongoing to reach some consensus before Nov. 30 on the duration beyond the March 2018 deadline," OPEC's Mohammad Barkindo told reporters.

"I have not heard so far any participating country that is violently objecting to extending the decision.

The producers are in the process of inviting other countries to the Nov. 30 meeting, Barkindo said, with a view to joining the deal. He declined to name the countries concerned. (Reporting by Alex Lawler and Shadia Nasralla; Editing by David Goodman)
