Vienna - The price for crude oil produced by the Organization of the Petroleum Exporting Countries (OPEC) gained slightly at the end of the week, ending a six-day slide, OPEC said on Monday.

One barrel (159 litres) of OPEC-produced crude stood at 95.33 dollars Friday, 0.04 dollars higher than the 95.29 dollars on the previous day.
