About The Position

EPAM is seeking an Experienced Reservoir Simulation Engineer to join its Energy practice (Energy Competency, Subsurface & Wells) in Houston, Texas. The role focuses on hands-on work with complex reservoir simulation models, including building, refactoring, converting, and quality-assuring dynamic models. The engineer will work directly with asset and subsurface teams to ensure models are technically robust and fit for use. Practical experience with CMG, Eclipse, or Intersect is required; experience with Intersect and migration between simulators is particularly valuable.

The position calls for a reservoir simulation specialist who can analyze existing complex models, understand their structure and behavior, rebuild or refactor them as needed, migrate them between simulation platforms, and demonstrate that the resulting models perform correctly.

Requirements

• Bachelor's or Master's degree in Petroleum Engineering, Reservoir Engineering, or a related discipline.
• Significant professional experience in reservoir simulation and dynamic reservoir modeling.
• Strong hands-on experience with at least one of CMG, Eclipse, or Intersect.
• Experience building, modifying, and troubleshooting complex reservoir simulation models.
• Strong understanding of reservoir simulation fundamentals, initialization, history matching, PVT, SCAL, and well modeling.
• Strong analytical, problem-solving, and technical communication skills.
• Houston-based, with the ability to work closely with local teams.

Nice To Haves

• Hands-on Intersect experience.
• Experience with two or more of CMG, Eclipse, and Intersect.
• Experience converting or migrating reservoir models between simulators.
• Experience with large, complex full-field models.
• Experience improving simulation performance, numerical stability, or model maintainability.

Responsibilities

• Build and refactor reservoir simulation models, including model setup, initialization, and configuration.
• Review existing simulation models and improve their structure, quality, robustness, and performance.
• Convert and migrate models between CMG, Eclipse, and/or Intersect, validating results after conversion.
• Troubleshoot model issues involving initialization, convergence, numerical stability, and simulation performance.
• Perform model QA/QC and identify inconsistencies in model configuration, data, and results.
• Support history matching and run simulation cases to confirm model behavior.
• Work closely with subsurface and asset teams to understand existing models, assumptions, and requirements.
• Document model changes, assumptions, validation results, and technical issues.
