On notice of a possible downgrade are Australia's Woodside Petroleum as well as multinationals Chevron, Exxon Mobil, Imperial Oil, Royal Dutch Shell, Shell Energy North America, Canadian Natural Resources, ConocoPhillips and French group Total. S&P said it was also considering downgrading four large Chinese producers – China Petrochemical Corp, China Petroleum & Chemical Corp, China National Offshore Oil Corp and CNOOC. The rating agency said it had increased its risk rating for the entire oil and gas sector from "intermediate" to "moderately high" because due to the move away from fossil fuels, poor profitability and volatile prices. It said it also had a negative outlook for two other big oil and gas companies, British multinational BP and Canadian group Suncor, but did not plan to immediately reassess their credit ratings.
