Crude oil prices remained above USD 74 per barrel on Tuesday, prompted by signs of tightening US oil supplies. The EIA’s data suggests that US shale oil production will likely decrease to nearly 9.4 mln barrels per day in August, the first reduction since December. However, oil prices fell almost 2% on Monday due to concerns about demand in China following weaker-than-anticipated economic growth. Meanwhile, two Libyan oil fields that halted operations last week resumed production on Saturday evening.
