Course Facts

Course Code:
4 days
3.2 Continuing Education Units
32 Professional Development Hours
Certificate Issued Upon Completion


This course addresses the fundamental core properties of interest to reservoir engineers, including: core characterisation; coring requirements for reservoir engineering purposes; measuring / assessing the effect of variations in porosity, fluid saturation, relative permeability, interfacial tension and capillary pressure and applying the resultant data reservoir analysis. There is some flexibility in the subjects covered during the course, based on participant experiences and interests. 

Duration and Training Method

Four-day, classroom based, with worked examples, hands-on exercises and practical discussion. Participants will have an opportunity to discuss their own data. Includes a visit to the ‘state of the art’ Heriot Watt core analysis laboratories.

  Participants will learn to:

  1. Charaterising the fundamentals of taking, analysing and assessing reservoir core material.
  2. Validating and synthesising the results of core analysis.
  3. Applications of core analysis data, production and injection estimates, reserve estimation using core data.
  4. Integrating the results of core analysis and other data into reservoir models.

There is some flexibility in the subjects covered during the course, based on participant experiences and interests, but some of the key areas that will be covered include:

• Core properties and characterisation
– including understanding the effect of rock mineralogy and depositional environment on the absolute value and lateral variations in porosity, fluid saturation and permeability.

• Core properties measurement techniques, corrections and laboratory artefacts.

• Coring requirements and techniques, core sampling and preservation.

• Initial reservoir conditions including the effects of surface kinetics, interfacial tension, wettability and capillary rise.

• Special core analysis techniques, capillary pressure theory and impacts on static multiphase fluid distribution and multiphase flow and displacement, two-phase and three-phase relative permeability measurements and correlations.• Understanding options for core relative permeability measurements, such as X-rays, steady and unsteady state flow experiments.

• Validating results, correcting for such factors as hysterisis and end effects; and combining data from several sources for application in two and three phase reservoir models.

• Relationship of core analysis and special core analysis. Dynamic reservoir conditions, including initial fluid saturations and the eff ect of relative permeability and residual saturations.

Who should attend

The course is designed for Petroleum Engineers and Geoscientists who need to understand what core analysis techniques are available and how analysis results can be used.

Prerequisites and linking courses

A basic understanding of core analysis methods and familiarity with basic petrophysical and reservoir engineering principles are helpful, but not essential. There are no formal prerequisites for this class.There are no formal linked classes to this one, however there are a number of classes on the Nautilus portfolio that compliment this class in relation to Fundamental Analysis, such as N934 (PVT) and N964 (Initialisation Strategies for Reservoir Simulation).
