Oil futures edged up on Thursday as a drop in crude exports from OPEC’s de facto leader, Saudi Arabia, and a draw in U.S. drilling rigs and oil inventories supported prices.
Brent crude futures settled at $71.97 a barrel, up 35 cents from their last close and near Wednesday’s five-month high of $72.27. Brent saw a weekly gain of 0.6 percent, marking the fourth consecutive weekly rise for the international benchmark.
In post-settlement trade, the contract added 4 cents to $72.01 a barrel.
U.S. West Texas Intermediate (WTI) crude futures settled at $64.00 a barrel, up 24.00 cents. U.S. futures gained just under 0.2 percent for the week, their seventh weekly gain in a row.
Many financial markets will be closed on Friday for public holidays.
Saudi Arabia’s crude oil exports fell by 277,000 barrels to just under 7 million bpd in February from the month before, according to data from the Joint Organizations Data Initiative (JODI).
U.S. crude, gasoline and distillate inventories dropped this week, with crude posting an unexpected drawdown, the first in four weeks, the Energy Information Administration (EIA) data showed on Wednesday.
“I think it’s pretty clear that tightening supplies and receding fears of demand growth is a boost to the market to these five month highs,” said Gene McGillian, vice president of market research at Tradition Energy in Stamford, Connecticut.
U.S. energy companies this week cut the number of oil drilling rigs for the first time in three weeks as production growth forecasts from shale, the country’s largest oil fields, continue to shrink.
The U.S. rig count, an early indicator of future output, fell by eight in the week ending April 18, General Electric Co’s Baker Hughes energy services firm said in its weekly report, which was released a day early because of the Good Friday holiday.
Oil has been driven up this year by an agreement reached by the Organization of the Petroleum Exporting Countries and its allies, including Russia, to limit their oil output by 1.2 million bpd.
Global supply has been tightened further by U.S. sanctions on OPEC members Venezuela and Iran.
Iran’s crude exports have fallen in April to their lowest daily level this year, tanker data showed and industry sources said, suggesting a reduction in buyer interest ahead of expected further pressure from Washington.
Strong U.S. retail sales data and earnings from industrial companies put global slowdown fears, sparked by underwhelming manufacturing surveys from Asia and Europe, on the back burner.
Thursday’s oil rally was kept in check, however, by a rise in the U.S. dollar, which makes crude more expensive for global buyers.
“A significant strengthening in the dollar, especially against the Euro, tended to limit buying interest,” Jim Ritterbusch, president of Ritterbusch and Associates, said in a note.
