World oil prices in the morning of September 17 slightly reduced. This is evidenced by the auction data.
At 7:36 GMT, the cost of November futures for the North sea oil mixture Brent decreased by 0.12% to 78 dollars per barrel, the price of October futures for WTI crude oil decreased by 0.07% to 68.72 dollars per barrel.
Bidders drew attention to Friday's data from the American oil and gas service company Baker Hughes, a GE Company (BHGE) on the increase in the number of oil drilling rigs in the United States for the week ended September 14.
The number of operating oil drilling rigs in the United States increased by seven pieces, or 0.8%, to 867 units, RIA Novosti reported.
In addition, the pressure on the oil market have concerns related to the trade conflict between the US and China. Traders fear that it may eventually negatively affect the demand for raw materials.
