PM 323 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.  Gas produced is re-injected to maintain pressure support, and oil is exported via a pipeline to an onshore oil terminal.

Completion of Jadestone’s acquisition of this interest occurred in August 2021.  PETRONAS Carigali holds the remaining 40% working interest.
