The world oil prices fell on Thursday after a significant increase a day before, since the investors decided to make profits, according to the auction. July cost for Brent Northern Sea petroleum mix declined from 0.27 % - to 47.47 dollars per barrel. June cost for WTI oil fell by 0.26 % - to 46.11 dollars per barrel , reports RIA Novosti.

The oil prices returned to the increase on Wednesday after the US Energy Department had issued data on unexpected reduction of the black gold’s weekly stocks by 3.4 million barrels , or 0.6 % - to 540 million barrels in the country. The analysts expected a growth rate of 0.714 million barrels - up to 544.114 million barrels . Against this background, Brent oil for the first time since May 2 rose above $ 47 per barrel.

" Many people think that yesterday's jump was rather high , and they decided to make profits this morning , as long as possible, " said one of the oil traders to Reuters.

In addition, the negative dynamics contributes to the gradual recovery of the Canadian production, where some of the oil companies suspended their work due to forest fires in the region.
