E-354 - Experimental Training for Core Analysis

5 days REE/CARC
Level
Proficiency
Audience
  • Reservoir engineers, petroleum engineers and experienced technicians involved in core analysis.
Purpose
  • This course provides a comprehensive and practical knowledge of how to carry out and interpret SCAL lab experiments.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • select methods for conventional and special core analysis,
  • explain and discuss the physical mechanisms behind core analysis and to describe experimental conditions.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Hands-on practice through real lab experiments carried out during the training.
  • CYDAR™ software is used to design and interpret the experiments and to perform additional exercises.

Introduction - Theory 1 day
  • Darcy's law, porosity, permeability.
  • Theory of multiphase flow (capillary pressure, relative permeability).
  • Description and preparation of the experiments that will be performed (principles, operating methodology).
Experiments 2 days
  • Porosity (Helium porosity, liquid saturation).
  • Permeability: steady-state with liquid, pulse-decay with gas.
  • Tracer test to characterize the heterogeneities.
  • Formation factor.
  • Relative permeability Kr: steady state and unsteady state method (water / oil).
Analysis & interpretation of experiments 2 days
  • Analysis of the experiments and discussion.
  • Generalities on data acquisition and data processing.
  • Notion of experimental errors and uncertainties.
  • Interpretation of Kr experiments by an analytical and numerical method with CYDAR™ software.
