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.

  • 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.
