Oil prices, considered "black gold", remain in positive territory, recovering from yesterday's drop triggered by fears of rising inflation in the US.

West Texas Intermediate (WTI), the "benchmark" for the United States, for December delivery adds 0.74% to $81.94 per barrel.

Meanwhile, the December North Sea Brent contract, traded in London and the benchmark for European imports, advances 0.29% to $82.88.

Trading has proven volatile on a day when the Organization of the Petroleum Exporting Countries (OPEC), in its monthly report on the crude market, said that high energy prices should mean less demand for oil.

Rising energy prices are expected to curb oil demand in some of the world's fastest growing economies this year, OPEC stressed.

In its monthly report, OPEC said that global demand for oil will grow by 5.7 million barrels per day this year, 160,000 barrels per day less than expected last month. The revision means that the oil producers' group expects oil demand in 2021 to total 96.4 million barrels per day.
