The XJ23-1 oil field is located in Block XJ04 in the Pearl River Mouth Basin, about 19km east of the XJ24-3 oil field. Its development facilities contain one platform, one floating, production, offloading and storage vessel, and 15 producing wells.

The field is producing approximately 31,000 barrels of oil per day through 10 wells. The other wells will start production in succession. The peak daily production of XJ23-1 is expected to hit 40,000 barrels.

The XJ23-1 was discovered in 2003. The China National Offshore Oil Corporation (CNOOC) holds a 100% interest of the field and acts as the operator.

Liu Jian, executive vice president of the company, said: XJ23-1 is one of the major projects we are working on in 2008, it is also the third field of the company which has commenced production this year. The start-up of XJ23-1 will strengthen our ability to realize this year’s production target as well as to benefit our long-term production growth in the eastern South China Sea.
