  Jr. Reservoir Simulation Engineer

  Worked on two full-field 3D dynamic reservoir modeling studies for different KKKS, involving contrasting reservoir characteristics and fluid types (volatile oil and retrograde condensate). Projects included both black oil and compositional modeling, utilizing Petrel RE-Eclipse and tNavigator for model construction, history matching, and production forecasting. Responsibilities included:• Performed quality control on static models before dynamic modelling process, ensuring proper grid sizing, fault modeling, and alignment of zone horizon with well zone-markers.• Validated volumetric calculations and checked model stability by reviewing barriers between zones of interest.• Analyzed PVT data (CCE, DL, and separator test) and built black oil and compositional fluid models for retrograde condensate and volatile oil reservoirs.• Conducted Decline Curve Analysis (DCA) for a field with 100+ wells and 42 tanks, evaluating future production performance.• Analyzed Drill Stem Test (DST) data to assist petrophysicists in fluid contact evaluation.• Initialized reservoir models by ensuring in-place volumes were accurately matched across key zones.• Successfully completed history matching for both black oil and retrograde condensate reservoirs.• Proposed workover candidates based on well log analysis and reservoir simulation results.• Applied and evaluated HCPV and SOI (Simulation Opportunity Index) post history matching to determine optimal infill well locations for production forecasting.• Prepared and delivered technical reports to clients and regulatory authorities.
