Senior Engineer, Reservoir Simulation

Role Overview

Senior Engineer, Reservoir Simulation at ADNOC. The role is based at an ADNOC location and focuses on updating and generating black oil and compositional simulation models to support field development planning and operational decision-making.

Role Purpose

Update and generate black oil and compositional simulation models aligned with field development planning, short and long-term profiles. Conduct model sensitivities, prioritize development schemes applying best practices, uncertainty and risk assessment, and economics. Undertake reservoir simulation studies to attain stated objectives and translate results into operational guidelines.

Key Responsibilities

Reservoir Characterization & Modelling
