Job Description

Accountabilities. Snr. Reservoir Engineer with experience in integrated reservoir studies and reservoir management of oilfields to optimize field development plans. Perform and provide technical supervision of the reservoir simulation modelling aspect, reservoir / well performance data analysis, reservoir surveillance program, infill and workover well programs and reservoir management activities.  Stewards and formulates detailed/integrated development plans for both developed and undeveloped hydrocarbon resources. The incumbent will mentor and coach less experienced Omani staff.

  • Job activities.  
  • Constructs and updates dynamic black oil and compositional reservoir models for field development planning.
  • Carries out the annual reserves review and generates long-term forecasts for business planning and drilling/workover schedule.
  • Identifies opportunities for maximising HC recoveries by evaluating well results and contributing to well planning, formation evaluation and WRM plans / activities during all stages of the field life-cycle, from appraisal strategy planning through early and mature field (re)development, to field or segment scale and well and reservoir optimisation.
  • Identifies and recommends target reservoirs/reservoir layers and determine well-reservoir contacts for new/replacement vertical/deviated/horizontal drill projects into to optimize field development.
  • Stewards and contributes to the well proposals/prognosis.
  • Stewards and participates in preparing detailed integrated development plans for undeveloped hydrocarbon resources.
  • Participates in Field annual reviews.
  • Supervises and recommends the acquisition of Reservoir Eng data and QA/QC Reservoir Eng data, maintaining Reservoir Eng databases.
  • Develops and prepares post-drill Reservoir Eng reports including integration of interpreted Reservoir Eng data with Geological & Petrophysical evaluations.
  • Manages the reservoir engineering data of the fields according to company standards.
  • Team member of a multi-disciplinary team. Participate in discipline activities in order to enhance sustainable production reservoir engineering capabilities.
  • QA/QC geological data and maintain reservoir engineering databases including real time data links.
  • Provides on-the-job coaching and development of Omani staff.
