Senior Engineer, Reservoir Simulation

About the Company

We are the largest oil producer within the ADNOC Group, accounting for over half of ADNOC’s total oil production. As the country’s oldest oil production company, our operations date back to 1939, when a 75-year concession was signed to explore for oil and gas in Abu Dhabi. As a global industry leader in environmental sustainability, we are the first in the world to capture carbon from the iron and steel industry.  Our Carbon Capture, Utilization, and Storage (CCUS) facility at Al Reyadah has the capacity to capture 800,000 tonnes of carbon dioxide (CO2) from Emirates Steel Industries (ESI) each year, for use in the Bab and Rumaitha oil fields to support Enhanced Oil Recovery (EOR). Al Reyadah is, therefore, a critical enabler of ADNOC’s 2030 sustainability goals. 

About the Job

Provides expert reservoirs engineering input to multidisciplinary projects including field development planning, reservoir performance analyses and reservoir estimation of production / injection capacities. Leads reservoir management studies, performance review and optimization using appropriate techniques.

Key Accountabilities
