JOB TITLE: SENIOR RESERVOIR ENGINEER II

KEY RESPONSIBILITIES:

1. Member of the subsurface team reporting directly to the Subsurface Team Lead but responsible to Head of Reservoir Engineering.
2. 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, reserves evaluation and field development plan.
3. Routine tasks include:
4. Maintain surveillance program to manage all PM304 producing reservoirs within reservoir management plan (RMP).
5. Maintain production and pressure databases.
6. Prepare short-term and long-term production forecasts for liftings, budgets and long-term planning.
7. Support and contribute to the preparation of appraisal/development well planning documents as required.
8. Prepare End of Year Reserves and support ARPR process.
9. Maintain reservoir simulation models to support reservoir development, depletion planning and reserves assessment.
10. Ensure integration of and consistency between engineering and geological interpretations by collaborating with reservoir and petroleum engineers, Petro physicists, geologists and geophysicists.
11. Implement reservoir engineering best practices and ensure adherence to company/PETRONAS standards, policies and guidelines.
12. Maintain the flow of data between Partners, Petronas and internal stakeholders.
13. Supervise and mentor less experienced engineers in all aspects of reservoir surveillance and management (if required).
14. Take ownership in day-to-day surveillance, reservoir management and development activities.
15. 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.
16. Identify/evaluate production enhancement opportunities and diagnostics of well behaviours.
17. Deliver and monitor reservoir management plan, field-wide surveillance programs and monthly target producing plans. Recommend and justify surveillance needs for wells.
18. Hold accountability on production forecasting. Monitor reserves changes and contribute relevant part of subsurface input to the annual business planning activities and quarterly updates to both internal and external stakeholders.
19. Undertake data analysis and interpretations, including material balance, volumetric estimation, production allocation and forecast, pressure transient analysis, nodal analysis, fluid contacts estimation, reserves evaluation etc.
20. Conduct reservoirs/field development studies (i.e. analytical and numerical simulation) to define optimal reservoir depletion strategy: optimize well locations and count, well utilities, pressure maintenance vs. gas cap blowdown, gas injection etc.
21. Integrate data from G&G, completions, drilling, and production operations and provide recommendations on subsurface optimization.
22. Support appraisal and development planning activities and provide reservoir engineering inputs and/or recommendations in a timely manner.
23. Prepare and update Field Development Plan (FDP) documentation for approval as required.
24. Deliver the necessary presentations and documentation for both technical assurance reviews and approval process as and when needed.
25. Provide mentoring and coaching to junior engineers as required.

ESSENTIAL QUALIFICATIONS AND SKILLS:

1. Degree in relevant subsurface discipline (reservoir/petroleum engineering) or equivalent.
2. Minimum 8 years relevant practical experience with at least 4 years in reservoir management/surveillance.
3. Experience in reservoir development, especially during drilling operations phase will be a plus.
4. Sound cross discipline skills, with an understanding from geoscience through reservoir engineering to petroleum and well engineering.
5. A good understanding of upstream processes.
6. Good working experience in all aspects of petroleum engineering, field reservoir development and ongoing production management through to abandonment.
7. Practical knowledge of well design and associated flow assurance issues (inc. Gas Lift Design, Sand Control, Corrosion, scale, wax etc).
8. Experienced in production enhancement justification and operations including: gas lift optimisation, perforations, scale & wax removal, stimulation.
9. Experienced in building and maintaining strong relationships with the Government, JV partners and Service Providers and managing associated contractual arrangements.
10. Clear understanding of hydrocarbon resource estimation and reserves audit procedures.
11. Be self-motivated to accomplish world-class results, generally positive in outlook, and able to cope in a dynamic environment.
12. Possess, or strive to possess, skills in project and team management, including planning of work, budgeting and control against plan and budget.
13. Have a sufficiently broad experience base to be able to exercise independent thought and decision making.
14. Good interpersonal skills, including ability to plan and present a coherent story to both direct reports as well as partners and management.
15. Computer literate and have a strong written and verbal command of English.
