Brent crude futures LCOc1 traded 15 cents lower at $69.11 a barrel at 1011 GMT. The contract broke above $70 a barrel on Thursday for the first time since December 2014.

“It is remarkable to see that most market analysts believe that prices have rallied too far since consensus forecasts is significantly lower than the current spot prices,” Hans van Cleef, senior energy economist at ABN Amro, said in a note.
Analysts and traders warned about the risks of a price correction since the start of 2018, but they say overall market conditions remain strong, mainly due to output cuts led by the Organization of the Petroleum Exporting Countries and Russia.
In addition to the OPEC and non-OPEC production cuts of 1.8 million barrels per day (bpd) that are expected to last until the end of 2018, oil prices have found support from eight consecutive weeks of U.S. crude inventory drops.
U.S. commercial crude oil stocks C-STK-T-EIA fell almost 5 million barrels in the week to Jan. 5, to 419.5 million barrels, or slightly below the five-year average of just over 420 million barrels, the target for OPEC and others involved in output cuts.
Relatively weak China December oil data weighed on prices, traders and analysts said. China’s crude imports in December fell 9 percent month-on-month to 33.7 million tonnes, or 7.97 million barrels per day, customs data showed.
“The end of year decline is highly counter-seasonal, being the first m-o-m decline in December in at least five years,” analysts at Vienna-based consultancy JBC Energy said.
An expected rise in U.S. oil production C-OUT-T-EIA to above 10 million bpd from 9.5 million bpd now has also weighed.
A market survey of more than 1,000 energy professionals conducted by Reuters in January showed crude price expectations in a range of $60 to $70 per barrel for 2018.
