* Libya’s Sharara oilfield shuts due to pipeline blockade

SINGAPORE, Aug 21 (Reuters) - Oil markets were stable early on Monday, holding on to Friday’s big gains even though rising U.S. output weighed on hopes the market will tighten with crude inventories down 13 percent since March.
Brent crude futures, the international benchmark for oil prices, were at $52.72 per barrel at 0139 GMT, unchanged from their last close.
U.S. West Texas Intermediate (WTI) crude futures were at $48.54 a barrel, up 3 cents form their last settlement.
This came after an up-to-3 percent increase in prices on Friday.
Traders said the market was somewhat held back by rising U.S. production, which has broken through 9.5 million barrels per day (bpd), its highest since July 2015. C-OUT-T-EIA
But the rise in U.S. output may soon slow, as energy firms cut rigs drilling for new oil for a second week in three, the Baker Hughes energy services firm reported on Friday. Drillers cut five oil rigs in the week to Aug. 18, bringing the total count down to 763, Baker Hughes said. RIG-OL-USA-BHI
“The rig count suffered its biggest fall since January, adding to signs that the market is tightening,” ANZ bank said on Monday.
Also, U.S. commercial crude inventories have fallen by almost 13 percent from their March peaks, to 466.5 million barrels. C-STK-T-EIA
Analysts said that falling crude inventories, despite rising output, indicate the market is already tightening.
“The rebalance of the oil market is well under way according to inventory data, however the market is heavily focused on the fact that shale supply continues to increase,” said William O’Loughlin, investment analyst at Australia’s Rivkin Securities.
“The trajectory of crude inventories is clearly down and it will be surprising if the market will be able to ignore continued drawdowns,” he added.
Outside the United States, an outage of the Sharara oilfield in Libya might dampen flows in the short-term, traders said.
