E-321 - Fundamentals of Reservoir Geology

15 days REE/RESGEOL
Level
Proficiency
Audience
  • Newly-hired or 2-3 years experienced reservoir engineers willing to deepen their knowledge in reservoir geology: geoscientists, petroleum engineers and production engineers moving towards reservoir engineering.
Purpose
  • This course provides a thorough understanding of reservoir geology, covering concepts as well as data reviewing and modeling.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • describe and explain main concepts of Reservoir Geology, especially petrophysical concepts, used in the description of the reservoir, and the way the data are measured,
  • deduce major reservoir properties from log interpretation and compare to core measurements,
  • define rock-types, determine electro-facies and derive K-Phi relationship,
  • integrate cores, logs and well tests data for reservoir modeling,
  • apply the workflow for building a reservoir model using dedicated software,
  • identify and assesse the uncertainties in order to reduce the risk and optimize the investments.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Interactive lectures, exercises.
  • Hands-on practice using software dedicated to reservoir modeling (EasyTrace™ and PETREL™).
