Oil prices were firm on Monday, supported by strong demand and political uncertainty in Syria, although another rise in U.S. drilling activity kept a lid on gains.
Brent crude futures, the international benchmark for oil, were at $55.39 per barrel at 0109 GMT, up 15 cents, or 0.3 percent, from their last close.
U.S. West Texas Intermediate (WTI) crude futures were up 24 cents, or 0.5 percent, at $52.48 a barrel.

U.S. bank Goldman Sachs said following the rig data release that year-on-year U.S. oil production would rise by 215,000 barrels per day in 2017 once a backlog of production waiting to be brought back online was taken into account.
