The Organization of the Petroleum Exporting Countries agreed in September to reduce output to help draw down a global supply glut that is weighing on oil prices, but left the details of the plan to be worked out later.

The technical meeting will prepare for OPEC’s ministerial meeting Nov. 30 in Vienna.
