Oil struggles as markets weigh U.S. drilling, OPEC cuts - Sean Seshadri

Oil prices swung between gains and losses in European trading on Monday, as the market weighed rising U.S. drilling against efforts by major producers to cut output to reduce a global glut.

The U.S. West Texas Intermediate crude July contract shed 6 cents, or around 0.1%, to $49.74 a barrel by 3:20AM ET (07:20GMT).

Elsewhere, Brent oil for August delivery on the ICE Futures Exchange in London dipped 5 cents to $52.46 a barrel.

Trading volumes were likely to remain light with U.S. markets closed Monday for Memorial Day while the U.K. is also shuttered for a public holiday.

Oil ministers from the Organization of Petroleum Exporting Countries and other major producing countries, such as Russia, agreed to extend supply cuts of 1.8 million barrels per day until the end of the first quarter of 2018.

While OPEC's move had been widely expected, some oil market investors had hoped producers would agree to longer or deeper cuts to drain a global glut of crude supplies.

So far, the production-cut agreement has had little impact on global inventory levels due to rising supply from producers not participating in the accord, such as Libya and Nigeria, and a relentless increase in U.S. shale oil output.

Data from energy services company Baker Hughes showed on Friday that U.S. drillers last week added rigs for the 19th week in a row, the longest such streak on record, implying that further gains in domestic production are ahead.

The U.S. rig count rose by 2 to 722, extending an 11-month drilling recovery to the highest level since April 2015.

Elsewhere on Nymex, gasoline futures for July inched down 0.2 cents to $1.623 a gallon, while July heating oil was little changed at $1.566 a gallon.

Natural gas futures for July delivery sank 7.8 cents to $3.232 per million British thermal units.

Crude prices gain slightly in Asia, U.S. rig count eyed - Sean Seshadri

Crude prices rose slightly in early Asia on Friday with weekly rig countfigures expected to set the near-term tone ahead of next week's meeting of OPEC and allied producers on production cuts.

On the New York Mercantile Exchange crude futures for June delivery edged up 0.04% to $49.37 a barrel, while on London's Intercontinental Exchange, Brent was last quoted at $52.49 a barrel.

In figures reported last Friday, oilfield servcies firm Baker Hughes said U.S. drillers added 9 oil rigs to take the total to 712, rigs for the 17th weekly gain in a row and extending an 11-month drilling recovery to the highest level since August 2015, implying that further gains in domestic production are ahead.

Overnight, crude futures settled higher on Thursday, as investors remained optimistic that OPEC would reach an agreement to extend the current supply-cut deal beyond June at its meeting next week.

In what was a choppy day of trade, oil futures recovered from a more than 1% slump, as investors' optimism that OPEC would seek an extension of the current deal to cut global production offset concerns over the rising level of U.S. shale production.

The Energy Information Administration said Wednesday, crude oil inventories fell by 1.75 million barrels last week, which was the sixth-straight week of declining crude stockpiles but the dip in inventories fell short of expectations of a draw of around 2.4 million barrels.

Despite the high level of compliance from OPEC members with the deal to rein in supply, global production remains above the five-year average, as non-OPEC members, who are not part of the supply-cut agreement have ramped up production.

In its monthly report last Thursday, OPEC estimated that non-OPEC production this year would grow by 950,000 barrels per day (bpd).

OPEC and other producers are set to meet on May 25 to decide whether to extend the current supply-cut deal amid growing optimism for a prolonged period of cuts.

Saudi Arabia and Russia agreed earlier this week that production cuts needed to be extended for a period of nine months until March 2018.

The International Energy Agency (IEA) on Wednesday, however, warned that OPEC’s effort to rein in the glut in supply may fail even if the oil group agrees to extend its supply-cut agreement.
