E-244C - Geological Characterization & Modeling - Integrated Workshop Certification

10 days GRE/IRCM
Level
Proficiency
Audience
  • Experienced geoscientists and reservoir engineers involved in multidisciplinary teams, willing to widen their knowledge in reservoir characterization and modeling
Purpose
  • To provide a comprehensive, practical knowledge of reservoir characterization & modeling workflow, via hands-on activities and case studies with the aim of bridging the gap between static geological characterization and reservoir dynamic behavior
Learning Objectives
  • To provide a clear understanding of techniques and challenges related to reservoir modeling (focus on reservoir properties)
  • To build required competencies for reservoir geoscientists to analyze a specific dataset and construct a reliable static model
  • To emphasize reservoir modeling main goal: reduce subsurface uncertainties (reduce risk and optimize investments)
Ways and means
  • Interactive lectures, videos, practical exercises and hands-on activities with the aim of producing a reservoir model using dedicated software for rock typing (EasyTrace) and geomodeling (Petrel)
