4 kboepd (2023 production)

Our Chim Sáo fields in Vietnam averaged 4 kboepd in 2023 (2022: 4 kboepd), with additions from new wells online offsetting natural decline. In August we announced the sale of our business in Vietnam to Big Energy Stock Company for $84 million. The divestment is expected to complete during 2024 and will result in a country exit from Vietnam for Harbour, as we continue to ensure that our capital and resources are deployed in line with our strategy.

The Chim Sáo oil field was discovered in 2006 and first oil was achieved in October 2011. Oil production is exported via a floating production storage and offloading (FPSO) vessel, and gas is exported by pipeline to Vung Tau near Ho Chi Minh City.

The Dua oil and gas field was subsequently developed as a subsea tie-back to Chim Sáo with first production achieved in July 2014.
