Oil edged up in early Asia trade on Friday, with U.S. crude trading near a two-month high after OPEC agreed to increase output curbs by nearly 50 percent in early 2020, although the cartel stopped short of promising any further steps after March.Higher oil prices are also supporting the initial public offering of Saudia Arabia’s state-owned oil company, Saudi Aramco, which said on Thursday it priced the shares on sale at the top of an indicated range.
