U.S. crude oil stocks last week fell for an eighth consecutive week to their lowest since January 2016, while gasoline stocks declined more than anticipated, the Energy Information Administration (EIA) said Aug. 23.

Crude inventories fell 3.3 million barrels (bbl) in the week ending Aug. 18, largely in line with expectations for a decrease of 3.5 million bbl. Overall U.S. crude stocks fell to 463.2 million bbl, a 14% drop from the peak of 535.5 million bbl at the end of March.

Oil prices have recovered from June lows as world supplies have started to tighten, in part due to efforts by OPEC, along with non-OPEC members, to pull back on production. The group agreed to cut supply by a combined 1.8 million bbl/d in a deal that extends to March of next year.

Oil prices have not been able to sustain much of a rally, though, and gains were meager after the government's report.

West Texas Intermediate (WTI) crude futures, which were rallying in the hours leading to the data, were up 21 cents to $48.06/bbl as of 9:49 a.m. CDT (14:49 GMT), while Brent futures gained 35 cents to $52.22/bbl.

"Crude draws were inline with expectations and the market initial reaction is mixed," said David Thompson, executive vice president at Powerhouse, an energy-specialized commodities broker in Washington.

"Increased crude oil imports and a drop in the refinery utilization rate open up the possibility of weakness in WTI," Thompson added.

U.S. crude imports rose last week by 605,000 bbl/d.

Refinery crude runs fell by 104,000 bbl/d, as utilization rates fell by 0.7 percentage point to 95.4% of total refining capacity, EIA data showed, as the summer driving season nears its end.

Crude stocks at the Cushing, Okla., delivery hub for U.S. crude futures fell by 503,000 bbl, the EIA said.

U.S. crude production, which has been growing steadily, rose 26,000 bbl/d to 9.53 million bbl/d. U.S. exports, which fluctuate on a weekly basis, rose to 936,000 bbl/d from 877,00 bbl/d the previous week.

Gasoline stocks fell by 1.2 million bbl, compared with expectations in a Reuters poll for a 643,000-bbl drop.

Distillate stockpiles, which include diesel and heating oil, rose by 28,000 bbl, vs. expectations for a 93,000-bl increase, EIA data showed.
