VIENNA The Organization of Petroleum Exporting Countries will likely decide to roll over oil production at its meeting on Friday, sources said, with Saudi Arabia telling other members it has no intention of floating a proposal for curbing output. Three OPEC delegates and sources said the group would maintain output without changing the current ceiling of 30 million barrels per day (bpd), sticking with its plan to defend market share rather than shore up prices at near seven-year lows. The group will likely postpone a technical increase in its ceiling to accommodate returning member Indonesia until next year, although one source said it may make a technical adjustment in the formal rate in order to match current output, which is running some 1.5 million bpd higher
