The PM 323 production sharing contract contains the producing Chermingat, East Belumut, and West Belumut fields. Each field has been developed by way of a wellhead platform, which are connected to a Central Processing Platform at the East Belumut field. Produced gas is re-injected to maintain pressure support, and oil is exported via a pipeline to an onshore oil terminal.
PETRONAS Carigali holds the remaining 40% working interest.
