Advanced Petrophysics and Formation Evaluation

Book now button

Course overview

The course is primarily intended for junior petrophysical staff to augment the skills that they should have already acquired during basic training. The course is also suitable for participants from other disciplines, who wish to have more insight into more advanced petrophysical analysis methods. Such participants should be familiar with basic petrophysical principles and will typically have 2 to 5 years or more working experience in a geoscience or reservoir engineering function.

The course is designed for:

    • The main emphasis during the course is on practical application rather than extensive discussion around the theoretical background.
    • The importance of the interaction between seismology, geology, petrophysics and reservoir engineering will be emphasised and illustrated.
    • All of the topics covered will be accompanied by a relevant exercise, which will be carried out using pre-programmed Excel spreadsheets that mimic the functionality of commercial log interpretation software. All participants will need to provide their own laptop with Excel (v2010 or later).
      • Exploration Geologists
      • Production Geologists
      • Well-site Geologists
      • Operations Geologists
      • Well Data Managers
      • Geophysicists
      • Petrophysicists
      • Geotechnicians
      • Others who use log data on a daily basis

Learning objectives

    • To undergo a basic review of the logging tools as well as the measurements made by the logging tools, and the transformation of the measured data into useful reservoir parameters such as Porosity, Permeability, and Water saturation for hydrocarbon reserves estimations
    • To understand the link and/or relation between Petrophysics and seismic interpretation, seismic reservoir characterisation and static reservoir modelling
