The Chim Sao oil field was discovered in 2006, and was approved for development by the Government of Vietnam in December 2009.
Oil production commenced in October 2011 from six wells. The gross production rate is expected to plateau at around 25,000 barrels of oil per day.
Gas will also be produced, with gross gas production expected to plateau at 25 million cubic feet per day.
The Chim Sao project includes a single wellhead platform and a floating, processing, storage and offloading (FPSO) vessel. Hydrocarbon processing will take place on the FPSO with the oil exported on crude offtake tankers and the gas by subsea pipeline into existing gas infrastructure. The gas will be used for power generation to meet domestic demand.
