The licence blocks, which are operated by PETRONAS Carigali, hold several producing oil and gas fields, including North Lukut, Penara, and Puteri.  The fields have been developed by way of fixed wellhead platforms, which are connected to the Bunga Kertas FPSO.

Completion of Jadestone’s acquisition of this interest occurred in August 2021.  PETRONAS Carigali is the operator, and holds the remaining 50% working interest.
