--FILE--Cars queue up to be refueled at a gas station of PetroChina, a subsidiary of CNPC (China National Petroleum Corporation), in Nanjing city, east China's Jiangsu province, 17 January 2015. China's leadership is exploring ways to consolidate the country's oil industry, creating new national champions able to take on the likes of Exxon MobilCorp. and operate more efficiently as prices slide. One option being studied by a team of advisers involves combining China National Petroleum Corp., or CNPC, and its main domestic rival, China Petrochemical Corp., or Sinopec, according to officials with knowledge of the research. Other options include merging two other major energy companies, China National Offshore Oil Corp., or Cnooc, and Sinochem Group. No timetable has been set for a decision on whether or when to proceed with any merger, said the officials. Spokespersons for the four Chinese oil companies and the State-owned Assets Supervision and Administration Commission, which oversees the largest state enterprises, declined to comment or didn't respond to queries.
