Principal Reservoir Simulation Engineer

Primary purpose: This position provides reservoir simulation engineering expertise for carbon sequestration projects during both feasibility and development phases. It operates within a multidisciplinary subsurface sequestration development team.

Essential duties and responsibilities: Conduct dynamic reservoir simulation studies for CCS projects and gas storage, including building and refining models to describe physical processes and optimize injection/operation conditions for permit applications. Collaborate with multidisciplinary teams to integrate well and reservoir data, forecast reservoir performance, support operational and subsurface development planning, and optimize asset development strategies. Apply fundamental reservoir engineering and simulation skills in reservoir characterization, opportunity assessment, and injection/production optimization. Interact with geoscientists, facilities engineers, petrophysicists, drilling, and production engineers to incorporate data into reservoir models. Identify key uncertainties and recommend risk mitigation strategies. Enhance reservoir descriptions through fluid analysis, core evaluation, well testing interpretation, and performance analysis, integrating findings into simulation models. Generate reports and visualizations to communicate field performance to management and peers. Demonstrate strong leadership, communication, and interpersonal skills, effectively managing multidisciplinary teams. Collaborate professionally with colleagues, maintaining tact, courtesy, and clarity in communication. Maintain dependable attendance and high-performance levels, working non-traditional hours as needed. Prioritize safety for personnel, assets, and the public. Perform other duties as assigned, including routine and special projects. Minimum requirements: Education: Bachelor’s degree from an accredited institution in Engineering is required. (Master’s / PHD is preferred).

Preferred Qualifications/ Experience: Experience with INTERSECT is a must. Past experience with Eclipse in CCS applications is a plus. Experience with Petrel RE workflows, Pipesim/nodal analysis, pressure transient testing is required. Experience in CO₂ EOR, core analysis, petrophysics, and programming languages (preferred but not mandatory). Competencies, Skills & Abilities: Minimum of 7 years’ reservoir simulation experience; candidates with less experience may be considered if they demonstrate exceptional skills or relevant expertise. Proven experience in reservoir simulation 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. Self-motivated, organized, and capable of managing multiple tasks under strict deadlines. Autonomous problem-solving skills, with the ability to seek guidance when necessary. Ability to work effectively in a team, follow directions, adhere to schedules, and pay attention to detail. Position level will be commensurate with experience and skills. Certifications, Licenses & Registrations: Valid driver’s license with a satisfactory driving record for travel purposes Physical Demands: Ability to sit, stand, walk, drive, and perform tasks requiring fine motor skills. Capable of lifting up to 25 lbs. occasionally. Visual and auditory acuity necessary for detailed work and communication. Work primarily in an office environment, with some travel to field sites. Working Conditions: Must pass a drug screen and background check prior to employment. Primarily office-based, with occasional fieldwork and travel. Flexibility to work after hours, nights, weekends, or holidays as needed. Supervisory Responsibility: None Other Responsibilities: This description reflects the general nature of the position. Additional duties may be assigned as needed. Equal Opportunity Statement: Tallgrass is an equal-opportunity employer.
