Senior Reservoir Engineer

About Us

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.

Position Purpose

Candidate will be reporting to Group Subsurface Manager and supporting the production and subsurface aspects of reservoir management and development activities for company's operated and non-operated assets, from pre-production to early and late-life production phases. Candidate will be responsible for performing reservoir engineering scope of work - analyse field data, perform wells and reservoirs studies to define optimum depletion mechanism and development strategy for optimizing production and maximizing the value of the asset. This includes accountability for the quality and the timely delivery of subsurface related deliverables such as preparation of robust production forecast, production enhancement activities, well/ reservoir surveillance activities, reservoir management and depletion plan, identifying targets for infill drilling, reserves evaluation and field development plan. The candidate will also be critical to performing short-term but objective asset evaluations to support the inorganic growth of the company across Australasia. In addition, the candidate will be working towards acquiring approvals for reservoir engineering deliverables presented to internal and external entities (partners, regulatory body, banks, and auditors). As a senior reservoir engineer, the candidate will be tasked to mentor and coach less experienced reservoir engineers and to participate in reservoir engineering focused and multi-disciplinary technical assurance review sessions to ensure the delivery of consistent high-quality products.

Principle Accountabilities

• Take ownership in day-to-day surveillance, reservoir management and development activities from assigned Jadestone's producing assets.
• Monitor production performance and make recommendations for production optimization. Work closely with operations, offshore personnel, facilities & engineering, drilling & completion and wells groups in ensuring smooth operations while achieving production targets
• Identify/evaluate production enhancement opportunities and diagnostics/mitigation of abnormal well behaviours.
• Deliver and monitor reservoir management plan, field-wide surveillance programs and monthly target producing plans. Recommend and justify surveillance needs for wells and production systems testing.
• Hold accountability on production allocation and forecasting. Monitor reserves changes and contribute relevant part of subsurface input to the annual corporate business plan activities and updates.
• Undertake data analysis and interpretations, including dynamic modelling, material balance, volumetric estimation, production allocation and forecast, pressure transient analysis, nodal analysis, fluid contacts estimation, reserves evaluation etc.
• Conduct reservoirs/field development studies (i.e. analytical and numerical simulation) to define optimal reservoir depletion strategy via IOR and/or EOR techniques: optimize well locations and count, well utilities, pressure maintenance vs. gas cap blowdown, ICD/ICV concept studies, inert gas injection etc.
• Integrate data from G&G, completions, drilling, and production operations and provide recommendations on subsurface optimization and evaluation/experimentation.
• Support exploration/appraisal and development planning activities and provide reservoir engineering inputs and/or recommendations in a timely manner.
• Prepare new and update Field Development Plan (FDP) documentation for approval by host government and co-ventures.
• Represent Jadestone for internal and external technical meetings / workshops (Jadestone internal, MPM, partner(s), banks, and auditors).
• Deliver the necessary presentations and documentation for both technical assurance reviews and approval process as and when needed.
• Provide mentoring and coaching to junior engineers.
