Job description / Role

About the Company:

ADNOC is one of the world's leading energy producers, and a primary catalyst for the growth and diversification of the United Arab Emirates. Our diverse family of more than 50,000 employees is made up of over 100 different nationalities. People from different backgrounds, with unique perspectives and wide-ranging skillsets, who share a collective responsibility: to enable and accelerate progress, both here in the UAE and across the globe. Here at ADNOC, we go beyond business as usual. We do things differently, challenge convention, and embrace new ways of thinking. This is what defines and differentiates us. By working together every day, we're bringing energy to life.

About the Job:
Update / Generate black oil and compositional simulation models with field development planning, short, and long-term profiles. Conduct model sensitivities and prioritize development schemes applying best practices, Uncertainty & Risk assessment and economics. Undertakes reservoir simulation studies to attain stated objectives and translate results into operational guidelines.

KEY ACCOUNTABILITIES:

Job Specific Accountabilities
- Coordinates and works with Geoscientists on reservoir characterization and upscaling.
- Builds sizable Full Field simulation models, history match and use them in predictions.
- Conducts quality check and consistency of simulation model, history match scenarios with respect to geological model characteristics.
- Develops characterization of reservoir fluids and Equation of State (EOS) modelling, calibration and Convert simple black oil models to compositional. Diagnoses model convergence and run-time problems.
- Coordinates with Technical centre in designing IOR/EOR methods (WI, Immiscible GI, Miscible GI, and Surfactant and polymer injection) to enhance recovery and pressure maintenance methods.
- Applies different methods of reserves estimation using probabilistic and deterministic methods (Mbal, DCA and simulation models sensitivities).
- Identifies required action using simulation models for maximize recovery/meet current production quotas, design, follow up, QC and analyse reservoir studies e.g. RCA, SCAL and PVT.
- Conducts special simulation studies for Field Development optimization (well pacing, infill wells, advanced wells, Pilots)
- Applies multiphase flow in the reservoir, effective permeability concept and correlations for relative permeability. Integrate pressure and production test results for reservoir simulation and management decisions.
- Contributes to reservoir monitoring program and data gathering with effective cost program to enable collecting necessary data to help best reservoir management and reduce uncertainties.
- Liaises with contractors conducting the study, analyses and reviews findings and actions study recommendations. Participate in periodic update and validation of database with monthly production/injection data and descriptions to display wells, reservoir and field performance for appropriate distribution and Simulation model recalibration.

Minimum Requirements:
- Bachelor Degree Reservoir/Petroleum/Chemical Engineering or equivalent.

Minimum Experience & Knowledge & Skills
- 6-8 years of experience in reservoir engineering including oil and gas fields' development management and Full Field simulation studies (use software models).
- Reservoir and Production Operations Knowledge.
- Analytical Reservoir characterization (Material Balance) knowledge
- Numerical reservoir simulation (Eclipse, Intersect)
- Pressure Transient Analysis and Well Performance knowledge, PVT Modelling

About the Company

We are one of the world's leading energy producers, and a primary catalyst for Abu Dhabi’s growth and diversification.

We operate across the entire hydrocarbon value chain, through a network of fully-integrated businesses, with interests that range from exploration, production, storage, refining and distribution, to the development of a wide-range of petrochemical products.

Since 1971, we have created thousands of jobs, driven the growth of a diverse knowledge-based economy, and played a key role in Abu Dhabi’s global emergence.

Today, we continue to look for new and innovative ways to maximize the value of our resources, pioneering those approaches and technologies that will ensure we are able to meet the demands of an ever-changing energy market, and continue to have a positive impact on the Abu Dhabi economy for generations to come.
