E-242C - Advanced Facies Analysis & Rock-Typing Certification

5 days
GRE/ROCKTYPE
Sessions
This course is not scheduled.
Who should attend?

Audience

    • Experienced geoscientists and reservoir engineers involved in multidisciplinary teams, willing to widen their knowledge in reservoir characterization.

Level

  • Advanced
  • This course develops an integrated approach to rock-type determination combining raw logs, interpreted logs from petrophysical evaluation, core description, and laboratory petrophysical data (routine core analysis and special core analysis). It details the quality control and processing which are necessary before the integration of such data. Interpretation techniques allowing a consistent integration of these different sources of data are developed based on probabilistic classification schemes. Various means to ensure the consistency between lithofacies and petrophysical rock-types incorporating SCAL data are discussed. Alternative approaches for rock-type determination based on specific porosity/permeability models are also presented. Eventually it is shown how the full rock-typing scheme is validated through the modeling of initial water saturation.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • understand the meaning of rock types and their contribution to reservoir modeling,
  • recognize log signatures (electrofacies) and tie them to core facies,
  • learn various porosity-permeability models and their use in rock-typing,
  • define rock types with petrophysical data (logs and laboratory data),
  • perform initial water saturation modeling as a QC of rock types.
