Subsea Flow Assurance Engineering


At GATE, we take subsea flow assurance engineering and modeling to operations. By using a systems engineering approach, GATE addresses the challenges from modeling to development of operational strategies to optimize flow assurance engineering in the production system.

Flow Assurance Modeling is a key aspect of engineering design work, especially in deepwater oil and gas developments. Several issues impact the flow of oil and gas from the sandface (near wellbore area) to the platform and through the export systems including slugging, hydrate management and formation, scale formation, wax buildup, corrosion, erosion, asphaltene deposition and gel formation.

At GATE, Flow Assurance engineering and modeling is designed to assist in project decision making, especially in the following areas:

  • Multiphase Flow Modeling Steady-State and Transient Modeling

    • Line Sizing and Thermohydraulics Studies

    • Shut-In, Start-Up, Restart, Ramp-Up/Down, Gas Lift

  • Production and Reservoir Engineering

    • Fluid Characterization (Oil, Gas, and Water), Production Profiles, Reservoir Pressure Behavior, Field Architecture Selection and Well Configurations and Optimization

  • Rigorous Choke Modeling

  • Chemical Systems

    • Chemical Injection Systems, Chemical Qualifications and Screening, and Umbilical Requirements

    • Integrating Production Chemistry to Flow Assurance Related Issues

  • Materials Engineering

    • Materials Selection and Requirements

  • Production Chemistry

    • Fluid Compatibilities, Emulsion Treatments, Foaming Control and Produced Water Treatment

  • Integrity Assurance

    • Corrosion Modeling, Erosion Modeling, Scale Modeling, and Souring Modeling

  • Operations and Procedure Development

    • Operating Guidelines and Specialized Procedures based on Steady‐state & Transient Flow Modeling
