Vienna - The price for crude oil produced by the Organization of the Petroleum Exporting Countries (OPEC) continued its bullish trend on Thursday, OPEC said on Friday.

One barrel (159 litres) of crude from OPEC's 13-brand reference basket stood at 98.63 dollars on Thursday, compared with 96.48 dollars the previous day.

OPEC's 13 cartel members produce approximately 40 per cent of the global crude output. (dpa)
