Fundamentals in Petrophysical Log Interpretation: Theory and Practice (PPH23)


    This course represents the fundaments of logging techniques and petrophysical models. It focuses on intuitive log reading and a mindful petrophysical setup. It supports your understanding of logging response in rough conditions as well as the awareness that models are helpful, but can also lead to incorrect interpretation. This course strengthens your confidence in log reading which helps in interpretation, reviewing or simply integrating logs in your daily work.

    This course is designed to give you a basic knowledge in the three main pillars in petrophysical log interpretation, which are:

    • The bits and bytes of wireline logs (data acquired)
    • Data integration (core, log, geological data)
    • Petrophysical theory and application

    When attending this course it is likely that you already had a petrophysical course at university or you already got in contact with wireline logs at your daily work. Maybe you got challenged by the question what those logs really mean in terms of vertical or horizontal resolution, what their significance or informative value is or how this can be translated into rock properties. Step by step, you will focus on specific physical properties and learn, what they tell us from the formation. You will learn the theoretical fundamentals for petrophysical log interpretation, the correct application for the reservoir present and about the uncertainty of the calculations. You will learn that the classical workflow needs back loops and data-integration to get reasonable results. During that investigation you will understand how logging techniques, borehole conditions or other external circumstances will influence your interpretation and how you can avoid pitfalls.

    Course Level: Foundation
    Duration: 5 days
    Instructor: Claudia Steiner-Luckabauer

    Designed for you, if you are...

    • A petrophysicist, geologist, reservoir engineer, geophysicist or someone in need of a basic understanding of petrophysical log interpretation

    How we build your confidence

    The course is structured in sequences of theory and practical exercises in which the discussed theories will be applied on real data.
    This course is based on real world examples. Such examples are not perfect and will be matter of discussion, as it will be also in the real working world. During this course you will learn how to apply accepted industry standard equations, what they are created for and in which circumstances they can be used.

    The benefits from attending

    By the end of the course you will feel confident in your understanding of:

    • The different definitions of terms to enhance understanding between people which leads directly to the definition of several petrophysical properties
    • 'Intuitive' log reading and qualitative log interpretation
    • The difference between deterministic and probabilistic log interpretation
    • The importance of data integration and integration of disciplines
    • How to perform qualitative log interpretation from data quality control to the calculation of porosity, water saturation and permeability
