Global oil prices has slipped away from two-and-a-half year highs hit the previous session as the gradual resumption of flows through a major North Sea pipeline made up for supply disruption in Libya.
But the two outages in quick succession have highlighted how much tighter global oil markets have become a year into supply cuts led by OPEC and Russia, reports Reuters.
US West Texas Intermediate (WTI) crude futures CLc1 were at $59.73 a barrel at 0421 GMT on Wednesday, down 24 cents from their last settlement.
WTI broke through $60 a barrel for the first time since June 2015 in the previous session.
Brent crude futures LCOc1 were at $66.71 a barrel, down 31 cents after breaking through $67 for the first time since May 2015 the previous day.
Libya lost around 90,000 barrels per day (bpd) of crude oil supplies from a blast on a pipeline feeding Es Sider port on Tuesday.
Wednesday’s dips were a result of the gradual return of the 450,000 bpd capacity Forties pipeline system in the North Sea. Flows through Forties will return to normal early in the New Year, operator Ineos said.
Both the Forties and Libyan outages, which together amount to around 500,000 bpd, are small in a global context where both production and demand are approaching 100 million bpd.
EIA data implies a slight supply shortfall of 180,000 bpd for the first quarter of 2018.
OPEC and Russia started withholding production last January, and the current schedule is to continue cutting throughout 2018.
A major factor countering efforts by OPEC and Russia efforts to prop up prices is U.S. oil production C-OUT-T-EIA, which has soared more than 16 percent since mid-2016 and is fast approaching 10 million bpd.
Only OPEC king-pin Saudi Arabia and Russia produce more.
The latest US production figures are due to be published by the EIA on Thursday.
