Operations Geologist

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 licenses, 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. The Company also has a 16.67% non-operated interest in the North West Shelf Oil Project offshore Western Australia, comprising four oil fields containing significant upside potential through potential infill drilling and life extension activities.

Further, the Company has a 100% operated working interest in two gas development blocks in Southwest Vietnam, and an operated 100% interest in the Lemang PSC, onshore Sumatra, Indonesia, which includes the Akatara gas field development, where first production is expected in the first half of 2024. Most recently, the Company acquired a non-operated 9.52% interest in the Sinphuhorm producing gas field onshore Thailand.

Led by an experienced management team with a track record of delivery, the Company is pursuing an acquisition strategy focused on growth and creating value through identifying, acquiring, developing and operating assets in the Asia Pacific region. Jadestone Energy plc is listed on the AIM market of the London Stock Exchange (AIM: "JSE"). The Company is headquartered in Singapore, has its principal technical team in Kuala Lumpur and country operational offices in Perth, Jakarta and Ho Chi Minh City.
