• Monitor daily production data, pressures, temperatures, and well operating parameters across the field.
• Perform well and reservoir surveillance through analysis of PI trends, water cut evolution, and pressure behaviour.
• Identify abnormal trends, underperforming wells, sand production, and water breakthroughs, and provide early warnings to operations teams.
• Monitor and optimise water injection performance, including tracking injection rates, pressures, voidage replacement ratio (VRR), and waterflood sweep efficiency. Recommend adjustments to ensure balanced reservoir support and mitigate breakthrough risks.
• Maintain and update field monitoring dashboards and surveillance systems (e.g., PI systems, real-time data platforms).
• Recommend development plans, such as well placements, workovers, and EOR/IOR strategies.
• Collaborate with geologists, petrophysicists, and drilling engineers to design optimal field development plans.
• Monitor field performance and identify opportunities to enhance production.
• Present technical findings and recommendations to management and multidisciplinary teams.
• Ensure data quality and maintain reservoir engineering databases and models.
• Support production optimisation by recommending choke adjustments, artificial lift tuning, and remedial actions.
