LONDON (AFP) - Oil prices edged higher on Monday, nearing 49 dollars in London as traders tracked efforts by OPEC members to enforce recent production cutbacks. Brent North Sea crude for delivery in March rose 35 cents to 48.72 dollars a barrel on London's InterContinental Exchange. New York's main futures contract, light sweet crude for March, added 27 cents to 46.74 dollars a barrel. "The focus would appear to have shifted away from weaker global demand and is centring on production dynamics," said analysts at British-based energy consultancy John Hall Associates. "OPEC members are now suggesting that the last round of production cuts agreed in December 2008 are beginning to impact the market." Crude futures had jumped by almost three dollars on Friday owing to expectations that stockpiles will ease as OPEC's member nations adhere strictly to their output cuts. The Organization of Petroleum Exporting Countries (OPEC) decided in December to cut production by 2.2 million barrels a day in a bid to halt the slide in prices and protect its members' revenues. Since September, OPEC has cut a total of 4.2 million barrels per day from its production to stem the fall in crude oil prices, which have plummeted by about 100 dollars a barrel since their record highs hit in July. OPEC's production fell by 1.5 million barrels per day in January to 26.1 mbpd, according to Petro-Logistics. "Production by those members bound by the agreement reveal that members are on course to have reduced production by some 1.5 mbpd or 5.5 percent in January compared with the previous month," said analysts at John Hall Associates analysts. "Previously, the market was sceptical whether OPEC had the collective discipline to make good the commitments agreed late last year. "Producers are keen to achieve what they consider to be some sort of balance in the market," the analysts added. This Friday, meanwhile, traders will seize on crucial economic growth data in the United States " which is the biggest consuming nation of crude oil. Experts believe that a stubborn global economic slump will continue to depress oil prices. Britain has slumped into a recession for the first time since 1991, official data had showed Friday. The eurozone, Japan and the United States are already battling a prolonged period of negative economic growth. A deepening global slowdown has slashed energy demand and pulled prices far below record highs of above 147 dollars a barrel reached last July when fears of tight supplies sent them rocketing.
