About the Development

The Chim Sáo project includes a single wellhead platform and a floating, processing, storage and offloading (FPSO) vessel. Dua was developed as a three-well subsea tie-back to the existing Chim Sáo facilities. Hydrocarbon processing takes place on the Lewek Emas 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.
