Oil headed for its biggest weekly gain in a month as the OPEC+ coalition\u2019s supply cuts and reduced output from the world\u2019s biggest offshore field overshadowed renewed concern over the U.S.-China trade war. Futures in New York were steady on Friday, and have increased 3.3 percent this week. Russia said it would accelerate the output cuts it agreed to in a deal with the OPEC+ alliance, while Saudi Arabia was said to curtail supply from the Safaniyah field to repair a damaged power cable. Asian stocks fell Friday as the U.S. and China were said to have made little progress in trade talks. Oil has resumed its rally this week - taking its advance this year to around 20 percent - after Saudi Arabia announced it would cut supply even further than agreed under a deal with fellow members of the Organization of Petroleum Exporting Countries and its allies. Still, record production and rising inventories in the U.S., together with prospects for weaker global growth, are capping gains. \u201cThe main drive of the upward momentum in oil prices finds its roots in the aggressive output cuts announced by the Saudi oil minister,\u201d said Harry Tchilinguirian, head of commodity-markets strategy at BNP Paribas SA in London. Also buoying prices is \u201cthe elephant in the room, which is Venezuela.\u201d Venezuelan exports are facing further disruption as the White House considers blocking foreign entities from dealing with the country\u2019s state oil giant Petroleos de Venezuela SA. The move would be a possible next step as the U.S. seeks to choke off President Nicolas Maduro\u2019s power.

Saudi Arabian Oil Co.\u2019s Safaniyah field has the capacity to pump 1.2 million to 1.5 million barrels of crude a day, and is a major component of the Arab Heavy grade. The cable was damaged in an accident about two weeks ago and repairs are expected to be completed by early March, people with knowledge of the matter said.
