Oil prices still near highest since mid-2015 on OPEC deal.
Oil fell on Monday after U.S. shale drillers last week added more rigs but prices still held close to their highest since mid-2015, supported by an extension to output cuts agreed last week by OPEC and other producers.

two oil rigs in the week to Dec. 1, bringing the total count to 749, the highest since September, energy services company Baker Hughes said in its closely followed report late on Friday. <RIG-OL-USA-BHI>
February Brent crude futures were down 62 cents at $63.11 a barrel by 1230 GMT, while U.S. West Texas Intermediate was down 63 cents at $57.73.
The Brent price hit a two-year high of $64.65 a month ago and has since attracted record investment by fund managers.
The U.S. rig count, an early indicator of future output, has risen sharply from 477 active rigs a year ago after energy companies boosted spending plans for 2017.
Drillers were encouraged during 2017 to increase activity as crude prices started recovering from a multi-year price slump after the Organization of the Petroleum Exporting Countries (OPEC) and some non-OPEC producers, including Russia, agreed to production cuts a year ago.
Last week the producers agreed to extend those cuts of 1.8 million barrels per day (bpd) until the end of next year.
"Market reaction has been positive so far. There are only two worrying aspects ... One is that Iraq’s indiscipline has not been discussed, at least not publicly," PVM Oil Associates strategist Tamas Varga said, referring to Baghdad's compliance with output cuts.
"The second is OPEC’s own forecast for next year. They are by far the most bullish on 2018, with the annual call on their oil at 33.42 million bpd," he said.
The forecast is much higher than those of the U.S. government at 32.70 million bpd and the International Energy Agency's prediction of 32.38 million bpd."
The latest agreement allows for producers to exit the deal early if the market overheats. Russian officials had expressed concern that extending the cuts might encourage U.S. shale oil companies
, which have been a thorn in OPEC's side, to pump more crude.
U.S. output rose in September to 9.5 million bpd, the highest monthly output since 9.6 million bpd in April 2015, government data shows. On an annual basis, U.S. output peaked at 9.6 million bpd in 1970.
