Advanced Flow Assurance Engineer


Spring, TX, US

Company:  ExxonMobil

Job Summary


The Advanced Flow Assurance Engineer is responsible for the design of oil and gas production systems and assessment of their operability; including wells, flowlines and risers, production and injection facilities, and pipelines.  The Advanced Flow Assurance Engineer uses analytical and computational tools to predict the transient multiphase flow and thermal behavior of the production system and develops and documents functional requirements and operational strategies to prevent, mitigate, and remediate vulnerabilities associated with gas hydrate formation, wax deposition, and other solids.

Primary Job Functions


Advanced Flow Assurance Engineers conduct technical studies to assess system operability, including:

• Fluid characterization using a thermodynamic simulator to model the PVT behavior of produced fluids
• Steady-state, single-phase flow modeling to size gas and/or water injection systems and pipelines
• Steady-state, multiphase fluid modeling to design production systems, including functional requirements for artificial lift and/or thermal insulation
• Transient, multiphase fluid modeling to assess thermal and hydraulic transients during production rate changes, turndown, startup, shutdown, and blow-down; including flowline and riser slugging, cool-down, and warm-up.
• Use of modeling and/or laboratory analysis to predict and assess solid formation, deposition, bedding and/or blockage behavior for hydrates, sand, wax, scale, asphaltenes, and other solids.
• Assessment of erosion and/or corrosion to guide proper material selection, conducted in collaboration with Materials Engineers.

Job Requirements


• B.S. in Mechanical Engineering, Chemical Engineering, Petroleum Engieering, or Aerospace Engineering
• Willingness and ability to travel internationally
• Demonstrated work experience (A minimum of 5 years) as a flow assurance engineer on an oil or gas field development project or in oil or gas field and facility operations
• Formal training and demonstrated work experience in OLGA transient multiphase flow modeling
• Demonstrated work experience in development of multicomponent fluid characterizations using  a thermodynamic or process simulator, such as PVTSIM, HYSYS, or equivalent
• Strong verbal communication and writing skills


Preferred Knowledge, Skills or Abilities

• Advanced degree (M.S. / Ph.D.) in Mechanical Engineering or Chemical Engineering
• Demonstrated work experience as a lead flow assurance engineer on a capital project
• Demonstrated work experience in prediction of gas hydrate formation and development of operational strategies for hydrate blockage prevention
