Senior Flow Assurance Well Performance Engineering Services

Position: Senior Flow Assurance /Well performance Engineer 
Location: 6-12 months France (Residential) , with relocation to Luanda for asset start-up and operations (Residential)
Start date : ASAP
Duration : 12 month renewable contract 
  Role Overview This role supports field operations through technical expertise in flow assurance and well performance. It involves preparing operational procedures, supporting start-up and ramp-up activities, and optimizing production and injection systems. The engineer will also lead simulation studies, maintain monitoring tools, and ensure well integrity and performance.

Key Responsibilities Well Performance

• Prepare start-up procedures and ramp-up strategies for production, water, and gas injection wells.
• Develop and deploy tools for well monitoring and analysis (e.g., DOF, GAP/PROSPER).
• Perform prognosis and update well potentials based on tests and network constraints.
• Validate well potentials and production targets in collaboration with reservoir and drilling teams.
• Support production/injection optimization and contribute to annual production budgets.
• Ensure well integrity and accurate production/injection data.
• Diagnose underperforming wells and propose corrective actions.
• Provide input for well interventions and quantify expected outcomes.
• Maintain confidentiality and ensure compliance with internal rules and standards.

Flow Assurance

• Provide operational and technical support through flow assurance studies.
• Prepare documentation for start-up and operations (e.g., hydrate prevention, pigging procedures).
• Address flow issues related to deposits (e.g., sand, asphaltenes) with production chemistry teams.
• Develop and maintain flow assurance monitoring tools (e.g., OLGA, LEDA, OCW).
• Optimize methanol consumption and monitor subsea system performance.
• Lead simulation studies for production optimization and facility modifications.
• Share best practices across assets and maintain flow assurance dossiers.

HSE & Compliance

• Promote a strong HSE culture and ensure adherence to safety and environmental standards.
• Support environmental management and energy efficiency initiatives.
• Ensure technical compliance with safety barriers and facility modifications.

Qualifications & Experience

• Education: Engineering degree or equivalent.
