What is a reservoir engineer?

The responsibilities of a reservoir engineer, also known as a petroleum or pipeline engineer, focus on optimizing the fluid flow of petroleum oil and gas through reservoirs. Your duties are to identify and evaluate each oil and gas reserve using special tools and equipment, continuously monitor and optimize the reserve during the drilling process, and analyze the flow mechanics of each reserve to ensure efficiency. Although reservoir engineers can complete some work off-site using computer models of reservoirs and frac sites, you typically travel to different job sites as needed and work long hours as projects develop.

What does a reservoir engineer do?

A Reservoir Engineer is a specialized professional in the oil and gas industry who evaluates oil and gas reservoirs to maximize extraction and recovery. They use advanced computer modeling, data analysis, and field studies to estimate reserves, plan production strategies, and monitor reservoir performance. Their work involves collaborating with geologists, drilling engineers, and production teams to ensure efficient and sustainable extraction. Reservoir Engineers also help determine the economic viability of projects and suggest enhanced recovery techniques when necessary.

What are the key skills and qualifications needed to thrive as a reservoir engineer, and why are they important?

To thrive as a Reservoir Engineer, you need a solid background in petroleum engineering, geology, and fluid mechanics, typically supported by a bachelor's degree in engineering or a related field. Proficiency in reservoir simulation software (e.g., Eclipse, Petrel) and understanding of data analysis tools are crucial, along with relevant certifications such as SPE membership. Strong analytical thinking, problem-solving skills, and effective communication help engineers work collaboratively and make data-driven decisions. These skills are vital for optimizing hydrocarbon recovery, maximizing reservoir performance, and ensuring the economic success of oil and gas projects.

What are some common challenges reservoir engineers face when working on multidisciplinary teams?

Reservoir Engineers often collaborate with geologists, production engineers, and drilling teams to maximize oil and gas recovery. One common challenge is aligning differing technical perspectives and priorities, especially when balancing short-term production targets with long-term reservoir management. Effective communication and a solid understanding of each discipline’s objectives are critical to ensure project success. Building strong relationships and staying adaptable can help Reservoir Engineers integrate diverse viewpoints and drive optimal solutions.

What is the difference between Reservoir Engineer vs Petroleum Engineer?

AspectReservoir EngineerPetroleum Engineer
Required CredentialsBachelor's degree in petroleum engineering, geology, or related field; often professional engineering licenseBachelor's degree in petroleum engineering or related field; often professional engineering license
Work EnvironmentFocuses on subsurface reservoir analysis, modeling, and simulationDesigns and implements drilling, completion, and production processes
Industry UsagePrimarily in exploration and production companies, focusing on reservoir managementInvolved across exploration, drilling, and production phases in oil and gas industry

Reservoir Engineers and Petroleum Engineers share similar educational backgrounds and work within the oil and gas industry. Reservoir Engineers specialize in analyzing subsurface reservoirs to optimize extraction, while Petroleum Engineers focus on designing and implementing drilling and production operations. Both roles are essential for efficient resource development and often collaborate closely.

Job description

CURRENT EMPLOYEES - Please apply using "Jobs Hub" in Workday. This career site is for external applicants only.

The Senior Reservoir Engineer is a recognized technical authority responsible for leading advanced reservoir engineering evaluations and shaping development strategy for unconventional assets. This role requires deep, hands on expertise in shale reservoir engineering, including RTA, PVT, DFIT, CPG interpretation, fracture modeling and reservoir simulation, complemented by modern analytics, including machine leaning, SQL-based data workflows, and visualization platforms (e.g., Spotfire). This engineer operates with a high degree of autonomy, influences asset level decisions, and provides technical mentorship across reservoir engineering teams.


Job Responsibilities:

Include but are not limited to

  • Serve as a technical authority for unconventional reservoir engineering, providing guidance on well performance, spacing, and development optimization.
  • Lead advanced RTA and diagnostics to evaluate DSU optimization, interference, depletion, and completion effectiveness.
  • Perform and oversee PVT, pressure, DFIT, and fracture data analysis to characterize reservoir properties, stress regimes, and fracture behavior.
  • Apply fracture modeling, reservoir simulation, and forecasting to support completion design, spacing decisions, and development planning.
  • Leverage advanced analytics, machine learning, SQL, and structured data workflows to identify performance drivers and screen opportunities across large datasets.
  • Develop and maintain Spotfire dashboards and analytical tools to support surveillance, diagnostics, and assetlevel decision making.
  • Provide economic evaluation and clear technical recommendations, collaborate crossfunctionally, and mentor reservoir engineers while communicating insights to leadership.

Required Qualifications:

  • Bachelor's degree in Petroleum Engineering or a related engineering discipline.
  • 10+ years of reservoir engineering experience, including at least 5 years focused on unconventional reservoirs.
  • Demonstrated technical mastery of RTA, PVT, DFIT, CPG, fracture modeling, and reservoir simulation.
  • Strong analytical capability with handson experience working with production, pressure, and completion data.
  • Proven ability to independently evaluate complex reservoir problems and influence development decisions.
