Jadestone Energy is an independent oil and gas production company focused on the Asia Pacific region. In 2021, Jadestone acquired SapuraOMV's assets in Peninsular Malaysia. These assets include interests in four licences, two of which Jadestone has operated since the 2021 acquisition. These include a 70 % operated interest in the PM329 PSC, containing the East Piatu field, and a 60 % operated interest in the PM323 PSC, which contains the East Belumut, West Belumut and Chermingat fields.

In addition, Jadestone acquired a 50 % non‑operated working interest in the PM318 and AAKBNLP PSCs, which were operated by PETRONAS Carigali. Jadestone assumed operatorship and full interest of those two PSCs in 2023 and is now engaged with PETRONAS on a path to unlocking additional value through these assets.

Outside of Malaysia, the Company has a 100 % operated working interest in the Stag oilfield and in the Montara project, both offshore Australia. Both the Stag and Montara assets include oil producing fields, with further development and exploration potential.
