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
