Level : Proficiency

Course Content

  • INTRODUCTION TO UPSCALING

      • Objectives of upscaling.
      • Why upscaling?
      • Aggregation rate, up-layering, heterogeneities, geological features.
      • Properties to upscale: porosity, net-to-gross, rock types, saturation, permeability.
  • UPSCALING METHODS

      • Algebraic methods: Cardwell and Parsons.
      • Numerical methods: flow based method.
      • Criteria to choose the upscaling method.
  • VALIDATION

      • Static validation: volumes, histograms.
      • Dynamic validation: volumes, simulation results on fine and coarse grids, well transmissivity.
  • UPSCALING WORKSHOP: REAL CASE STUDY

      • Geological model: heterogeneities.
      • Facies proportion curves analysis.
      • Up-layering definition: choice of the most appropriate up-layering.
      • Zone division and zone mapping.
      • Scale-up properties methodology: choice of the most appropriate method.
      • Volume calculation: static validation.
      • Dynamic validation: simulation and comparisons with the fine model.
      • Synthesis and wrap-up.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • recognize the techniques and challenges related to upscaling (properties, methods, validation),
  • build required competencies to analyze reservoir heterogeneities in order to define the aggregation rate,
  • apply the workflow for generating an upscaled grid using dedicated software Petrel™ and Eclipse™,
  • validate the upscaled grid (static and dynamic models).

Ways & Means

  • Interactive presentations, hands-on real case study using software dedicated for reservoir modeling: Petrel™ and Eclipse™.
