Project Overview

The Chim Sáo oil field was discovered in 2006 and is located in the Nam Con Son Basin, approximately 350 km offshore southern Vietnam within exploration Block 12W.

Chim Sáo oil and associated gas is being produced via an unmanned, minimum facility wellhead platform located in approximately 100 metres of water. Liquids are exported form platform via FPSO and gas offtake is connected to the existing Nam Con Son pipeline via an approximately 100 kilometre pipeline.

The processing and offtake facilities have a plateau production of 25,000 bbl/day (gross). Associated sales gas is compressed and exported to the Vietnamese domestic gas market.

The Chim Sáo field proven and probable (2P) reservers are estimated at approximately 50 mmboe (Santos share approximately 15.5 mmboe).

In 2014 the Dua field was successfully tied into the Chim Sáo facilities. Two additional Chim Sáo water injection wells were drilled during 2014 for reservoir pressure maintenance as part of the field development plan.

In January 2015 the 100th cargo of crude oil was loaded from the Chim Sáo FPSO.

Production and Sales

Production commenced on 11 October 2011 with an initial production rate of approximately 25,000 barrels per day.

More than 29 million barrels of oil have been shipped since the start-up of Chim Sáo field in October 2011.
