Vienna - The price for oil produced by the Organization of Petroleum Exporting Countries (OPEC) rose slightly to 47.18 dollars Wednesday after having shed more than 4 dollars since the end of last week, the group announced Thursday.

One barrel (159 litres) of OPEC-produced crude gained 0.53 dollars at mid-week. The Vienna-based oil cartel calculates a basket price based on 12 brands produced by its members. (dpa)
