Specialist Reservoir Engineer

Role Overview

Specialist Reservoir Engineer at KBR. The Reservoir Engineer Specialist is responsible for leading the development, maintenance, and application of integrated static and dynamic reservoir simulation models to support field development decisions and ensure alignment with company governance requirements.

Role Purpose

Develop fit-for-purpose, history-matched dynamic simulation models that integrate multi-disciplinary data to support field development optimization, well placement, production forecasting, and ensure all technical outputs are decision-ready and defensible for governance endorsement.

Key Responsibilities

Model Development & Validation

• Develop fit-for-purpose, history-matched dynamic simulation models.
• Integrate multi-disciplinary data including geology, petrophysics, PVT, SCAL, pressure, and production data to ensure physics-consistent modelling.
• Perform data quality control and integration across seismic, SCAL, logs, and pressure datasets.
• Achieve robust history match across multiple data domains.
• Deliver audit-ready assumptions and uncertainty documentation.

Field Development & Production Support

• Support field development optimization, well placement, and production forecasting.
• Deliver production forecasts and development scenarios.
• Support field development strategy and FDP optimization targets.
• Develop sensitivity cases and scenario testing.
• Evaluate recovery mechanisms and production sustainability.

Uncertainty & Risk Quantification

• Conduct STOIIP uncertainty analysis and assessment.
• Develop P10, P50, and P90 ranges and risked production outlooks.
• Quantify uncertainty in reservoir behaviour and connectivity.
• Perform reservoir performance risk analysis.
• Deliver uncertainty reduction plans.

Technical Governance & Stakeholder Engagement

• Act as technical focal point for simulation-related deliverables in governance meetings and workshops.
• Deliver clear and defensible technical presentations.
• Prepare pre-validated, endorsement-ready technical packages.
• Ensure all model outputs are defensible, auditable, and technically justified.
• Present model re-evaluation results to stakeholders.
• Align multiple stakeholders across field development, production engineering, geology, and upstream teams.
• Interface with geology, petrophysics, production, and facilities teams.

Model Maintenance & Continuous Improvement

• Support management framework and continuous model updates using new data.
• Update models using new wells, pressure, and surveillance data.
• Maintain alignment with Integrated Reservoir Management and audit requirements.
• Support continuous updates, re-runs, and scenario testing.
• Own the model lifecycle from build through updates and application.

Operational Delivery

• Balance model complexity with practicality.
• Manage multiple parallel deliverables, workshops, committees, and support requests.
• Maintain responsiveness to urgent simulation requirements.
• Prioritize under pressure.
• Adhere to company policies, systems, processes, and procedures.

Compliance & Standards

• Comply with applicable HSE policies, procedures, controls, legislation, sustainability guidelines, international standards, best practices, and company codes of practice.
• Implement approved department policies, processes, systems, standards, and procedures in line with company and international standards.

Qualifications & Experience

• Demonstrated functional experience in integrated reservoir modelling, including static and dynamic simulation modelling.
• Expertise in 3D model building, initialization, history matching, and uncertainty handling.
• Advanced experience in dynamic simulation, forecasting development scenarios, sensitivity analysis, and uncertainty quantification.
• Field development planning integration experience, including production targets, recovery factors, well placement, and pressure maintenance.
• Proven experience in uncertainty, risk, and decision analysis, including STOIIP assessment and P10, P50, P90 scenario development.
• Background in development optimization and strategy design, including well placement optimization, injection strategy, VRR management, and recovery mechanism evaluation.
• Experience in governance and stakeholder interface, delivering technical presentations and approval packages.
• Cross-disciplinary collaboration experience with geology, drilling, facilities, and production teams.
• Exposure to business planning and economics, including production profiles for business planning and support for economic evaluations.

Skills & Competencies

• Static and dynamic reservoir simulation modelling.
• Advanced reservoir physics understanding, including SCAL workflows.
• Uncertainty quantification and risk analysis.
• Ability to translate complex subsurface behaviour into clear outputs.
• Coordinate effectively with multi-disciplinary teams.
• Ensure integration across static, dynamic, and development workflows.
• Deliver defensible technical presentations.
• Strong understanding of Integrated Reservoir Management requirements.

Additional Information

• Expected deliverables in first 6 to 12 months include: integrated static-dynamic simulation model, history-matched reservoir model, audit-ready documentation, endorsement-ready technical packages, production forecasts and development scenarios, sensitivity cases, STOIIP uncertainty analysis with P10, P50, P90 ranges, risked production outlooks, continuous model updates aligned with IRM requirements, and fully integrated and technically consistent subsurface models across cross-functional teams.
