Oil prices rose Monday in anticipation of a production cut announcement by OPEC members later this week.

In late-morning trading on the New York Mercantile Exchange, light sweet crude for January delivery was up $1.14 at $47.42 US. Earlier, the price for a barrel of oil briefly traded at over $50 US.

The members of the Organization of Petroleum Exporting Countries are expected to make a large cut to their output at a meeting Wednesday in Algeria.

"The extent of such cuts is still unclear and this uncertainty has been a source of continuing volatility in futures markets," said a report from analysts at KBC Market Services in Great Britain.

Christopher Moltke-Leth, the head of sales trading at investment firm Saxo Capital Markets in Singapore, questioned whether OPEC members will have the discipline to stick to a reduced production targert.

"Unless they really surprise the market, this cut may not support the price much," he said.

Down about $100 a barrel from its high in July, the price of oil has wilted amid worries about the state of the global economy.

Moltke-Leth said he expects crude to keep sliding, predicting the price could get as low as $30 US per barrel.
