LONDON, Feb 13 (Reuters) - Oil prices rose on Thursday as U.S. markets opened, shrugging off bearish OPEC and IEA reports which cut back demand forecasts for this year on the back of the coronavirus outbreak in China, the world's biggest oil importer.

Paring losses from earlier in the session, Brent crude was up 64 cents to $56.43 a barrel by 1438 GMT, while U.S. West Texas Intermediate (WTI) was up 51 cents at $51.68.

Oil demand in China, the world's second-largest crude consumer, has plunged because of travel restrictions to and from the country and quarantines within it.

Hubei province, the epicentre of the outbreak, said on Thursday the number of new confirmed cases there jumped by 14,840 to 48,206 on Feb. 12 and that deaths climbed by a daily record of 242 to 1,310, reflecting changes to the diagnostic methodology.

Oil refiner China National Chemical Corp said on Thursday it would close a 100,000 barrel per day (bpd) plant and cut processing at two others amid falling fuel demand.

The International Energy Agency (IEA) expects oil demand in the first quarter to fall for the first time in 10 years before picking up from the second quarter. The agency cut its full-year global growth forecast to 825,000 bpd.

"(It's) worth noting that these forecasters are for now assuming a V-shape recovery in oil demand, with the bulk of the impairment concentrated in Q1, 2020," BNP Paribas analyst Harry Tchilinguirian told the Reuters Global Oil Forum. On the supply side, the Organization of Petroleum Exporting Countries (OPEC) lowered its 2020 demand forecast for its crude by 200,000 bpd, prompting expectations the producer group and its allies, known as OPEC+, could agree further output cuts when they next meet, possibly as early as this month.

Brent and WTI have fallen more than 20% from their January peak because of the disease outbreak.

Lower fuel demand expectations because of the virus have also shifted the market structure for both Brent and WTI into a contango - where prompt prices are lower than those for later dates.

The six-months spread of Brent futures contracts <LCOc1-LCoc7> is at about minus 32 cents.

Reflecting a well-supplied market, U.S. crude inventories in the week to Feb. 7 increased by a more than expected 7.5 million barrels, the Energy Information Administration said on Wednesday.

Meanwhile, a report by consultancy Wood Mackenzie about Nigeria said cost increases and uncertainty could lead to a 35% decline in oil output there over 10 years.
