E-222 - Fundamentals of Facies Analysis & Rock-Typing

  • Geologists, geophysicists and reservoir engineers involved in integrated reservoir studies.
  • This course provides participants with an integrated approach to facies analysis and rock-typing combining logs, core description, and laboratory petrophysical data.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • identify electrofacies from logs.
  • identify log signatures and facies association,
  • define rock-types with petrophysical data (logs and laboratory data),
  • define Petrofacies from various relationships like Reservoir Quality Index, Winland R35 for net pay determination and other poro-perm transforms.
  • No prerequisites for this course.
Ways and means
  • Interactive presentations, practical exercises and hands-on activities.
