Principal Reservoir Simulation Engineer

Tallgrass•Houston, TX

About The Position

This position provides reservoir simulation engineering expertise for carbon sequestration projects during feasibility and development phases as part of a multidisciplinary subsurface sequestration development team. The role conducts dynamic reservoir simulation studies for carbon capture and storage (CCS) projects and gas storage, building and refining models to describe physical processes and optimize injection and operating conditions for permit applications. It integrates well and reservoir data to forecast performance and support operational and subsurface development planning and asset strategy. The engineer also identifies uncertainties and mitigation strategies, enhances reservoir descriptions using fluid analysis, core evaluation, well-test interpretation, and performance analysis, and communicates field performance through reports and visualizations. The position requires leadership and effective collaboration across disciplines, prioritizes safety, and may involve non-traditional hours and field travel. The position level is commensurate with experience and skills.

Requirements

Bachelor’s degree in Engineering from an accredited institution.
At least 7 years of reservoir simulation experience; candidates with less experience may be considered if they demonstrate exceptional skills or relevant expertise.
Experience with INTERSECT.
Experience with Petrel RE workflows, Pipesim/nodal analysis, and pressure transient testing.
Proven reservoir simulation experience for CCS projects, including model construction, updating, and history matching.
Working knowledge of CCS operations, project management, and regulatory compliance.
Proficiency in basic engineering principles.
Valid driver’s license and satisfactory driving record for travel purposes.
Ability to manage multiple tasks under strict deadlines, solve problems autonomously, work effectively in a team, follow directions and schedules, and pay attention to detail.
Ability to sit, stand, walk, drive, perform fine motor tasks, and occasionally lift up to 25 lbs.
Visual and auditory acuity necessary for detailed work and communication.
Must pass a drug screen and background check before employment.
