Oil prices fell nearly 2 percent on Thursday, as the market took a closer look at US government data that showed growing inventories of gasoline and other oil products pushed total petroleum supplies in the world's largest oil consumer to a record high.
The previous session, Brent and US crude futures rose by up to 1 percent after the Energy Information Administration (EIA) said crude inventories dropped 2.3 million barrels last week, versus forecasts for a 2.1 million barrels decline. It was the ninth straight weekly draw.
Still, US crude inventories are at a historically high 519.5 million barrels for this time of year, the EIA said. Brent crude was down 79 cents, or 1.7 percent, at $46.38 a barrel by 11:41 a.m. EDT. US West Texas Intermediate (WTI) crude fell 84 cents, or 1.8 percent, to $44.91.
Market intelligence firm Genscape reported a build of 725,176 barrels during the week to July 19 at the Cushing, Oklahoma delivery point for US crude futures, traders said.
"The market is technically weak, inventories are still high for summer, maintenance season is not far off and we have floating barrels at sea to top it all," said Pete Donovan, broker at Liquidity Energy in New York.
ABN AMRO senior energy economist Hans van Cleef said Brent could slip toward the $42-$43 level. "Near-term, there are still some downside risks."
The spread between crude for near-term and forward delivery widened this week as the refined products glut worsened oil's outlook. The December 2016-December 2017 spread, for instance, hit record highs.
Phil Davis, a trader at PSW Investments in California, also pointed to the 4.2 million-barrel build of "other oils" cited by the EIA, which eclipsed the gasoline build.
The other oils include special gas for smaller airplanes and less-known industrial oils, which refiners typically crank out when there is too much gasoline and distillate supply, Davis said.
"These other oils don't get as much attention as the headline numbers put out by the EIA and have been a clever and convenient way to hide weak product demand," he said.
Lending some fundamental support to crude, exports of Nigeria's largest crude oil stream, Qua Iboe, will remain under force majeure for at least one month as operator ExxonMobil fixes a pipeline, sources said.
