For oil and gas exploration, Cambodia has established six offshore blocks (A-F), nineteen onshore
blocks (I-XIX) and four blocks in an overlapping claims area (OCA) that is contested with Thailand.
Offshore Block A is likely to be the first to produce oil. The government has estimated that the field
holds 30 million barrels of oil, which could be recovered over nine years. In August 2017 the
government signed a production-sharing agreement with Singapore-listed KrisEnergy, which holds
the rights to develop Block A.
Production of oil is slowly getting closer. In late 2018, Singapore company Keppel Offshore & Marine was contracted to modify and upgrade a production barge for use in the Apsara oil field in Block A. Oil industry publications say the barge will be able to process up to 30,000 barrels of fluid per day and be able to separate oil, gas and water. Plans for the first stage of production include a single unmanned wellhead platform and a moored production barge. Crude oil will be piped to a storage and offloading vessel approximately 1.5 km away.
