About the role

Key responsibilities & impact

Develop and apply reservoir simulation models to evaluate CO₂ injection performance, plume migration, pressure response, storage efficiency, and long-term containment for Class VI and Class II projects.
Support development of Engineering Well Designs (EWDs) for CO₂ injection and monitoring wells through integrated reservoir engineering analysis.
Provide technical reservoir engineering evaluations to support CCUS project screening, feasibility assessments, and commercial development opportunities aligned with EQT's CCUS strategy.
Analyze and interpret field test data, injection performance, pressure transient behavior, and production response to calibrate reservoir models and improve predictive capability.
Quantify and update CO₂ storage capacity, reserves, and resource estimates using reservoir simulation, geologic characterization, and operational data.
Advance EQT's technical capabilities in CO₂ storage and enhanced recovery (ER) reservoir modeling through benchmarking, workflow development, and integration of industry best practices.
Lead reservoir modeling and simulation efforts for Class II enhanced recovery projects and associated CO₂ storage in depleted Marcellus and Utica reservoirs.
Develop static and dynamic reservoir models to evaluate injectivity, containment, pressure management, recovery performance, and long-term storage behavior.
Generate injection and production forecasts to support well design, operational planning, workover requirements, and commercial evaluations.
Perform reservoir engineering analyses for Class VI geologic storage projects, including pressure modeling, plume migration assessment, and storage optimization.
Analyze and interpret results from CCUS field pilots and injection tests, including model calibration, uncertainty analysis, and technical reporting.
Collaborate with Geoscience, Completions, and Reservoir Engineering teams to integrate data and improve subsurface understanding and model accuracy.
Interface with external technical consultants, research organizations, and industry partners on reservoir simulation studies and subsurface evaluations.
