Job purpose

• Provide technical leadership in reservoir engineering and dynamic reservoir simulation to support subsurface development, reservoir management, reserves maturation, production optimization, and field development planning by:
• 1. Conducting integrated reservoir engineering workflows encompassing well test design/interpretation, advanced production diagnostics including decline curve analysis, material balance, and rate-transient analysis.
• 2. Monitoring, reviewing, and providing technical guidance for subsurface surveillance activities, including well performance tracking, fluid sampling programs, well testing operations, and completion/workover activities.
• 3. Directing PVT and SCAL laboratory experiments from design through application, managing and QC-ing existing lab datasets, performing PVT data analysis, and developing fit-for-purpose Equations of State models and Black Oil Tables for use in simulation and production engineering workflows.
• 4. Leading the construction, initialization, history matching, and production forecasting of dynamic reservoir simulation models, ensuring that models are fit-for-purpose and technically robust, to support field development decisions, reservoir management, and reserves maturation. 5)
• Contributing to field development planning and reservoir management strategy development, including the identification, evaluation, and maturation of IOR/EOR opportunities from initial screening and feasibility assessment through pilot design and potential full-field implementation. 6)
• Manage annual reserves certification in compliance with company standards and recognized industry guidelines.
• 7. Working in collaboratively with multidisciplinary teams, including geoscience, drilling, production engineering, facilities, and economics.
• The position will act in accordance with the Group’s Mission, Vision, Values & Strategies, as well as, policies, guidelines and standards, supported by an IT Technology platform, HSE standards, Omani’s government & other legal justification’s, and best international practices in consonance with national objectives.

Main tasks and responsibilities

• Provide technical guidance and support to help achieve the company’s performance objectives.
• Support management and the reservoir team in maintaining high technical standards and consistent reservoir engineering best practices.
• Support reserves maturation, production optimization, and field development planning.
• Evaluate well/reservoir performance and Recommend production improvement opportunities.
• Conduct PTA, RTA, material balance calculation, MDT interpretation, and DCA as required.
• Monitor wells performance, pressure trends, fluid sampling, well testing, and workover activities.
• Recommend reservoir surveillance and data acquisition programs.
• Integrate pressure, production, PVT, SCAL, and surveillance data into reservoir studies and models.
• Evaluate IOR/EOR opportunities from screening to pilot design and potential full-field implementation.
• Lead and support dynamic reservoir model construction, initialization, history matching, and forecasting.
• Provide technical guidance and assurance for reservoir engineering studies and models.
• Manage annual reserves certification in line with company standards and industry guidelines.
• Coach and mentor early career reservoir engineers.
