Foundations of Petrophysics (PPH01)

    Description

    The main objectives of this course are to understand:
    • The petrophysical properties and corresponding logging methods
    • The fundamentals of log interpretation and formation evaluation
    • The link between petrophysics and seismic reservoir

    The course presents in a first part the fundamentals of physical rock properties (pore space properties, permeability, density, electrical, acoustic, nuclear and mechanical properties, NMR physics) based on experimental data and theoretical rock model concepts). In a second part the physical principle of most applied logging methods are presented and in a third part relationships between the different properties are applied on techniques in well logging/formation evaluation and some seismic interpretation topics (AVO). Methods are trained at real log examples for sandstone and carbonate reservoir formations.

    Course Level: Basic
    Instructor: Jürgen Schön

    Designed for you, if you are...

    • A member of E&P staff with limited background in petrophysics and formation evaluation
    • A beginner in log interpretation and petrophysical interpretation of seismic data

    How we build your confidence

    • You will refresh your knowledge about the basic reservoir properties (porosity, saturation, permeability)
    • You will learn the fundamentals of logging methods (physical principle, measured parameter) and petrophysical principles of data interpretation
    • We compile algorithms related to typical cases of formation evaluation (sandstone reservoir and carbonate reservoir)
    • We develop your knowledge using real log examples, take a `quick-look` first interpretations and manually calculate levels of reservoir parameters (pocket calculator, excel-sheet)

    Please note: The course is not a training course on specialist software but delivers many of the frequently used algorithms of such programs.

    The benefits from attending

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

    • The position of petrophysics in the workflow of reservoir evaluation and characterisation
    • The physical reservoir properties (porosity, saturation, fluids, permeability, capillary pressure) required for clastic and carbonate rock evaluation
    • The physical background of well logging methods and the response with respect to reservoir characterisation (physical principle and primary information from logging methods)
    • Rules for an optimal log combination
    • Basic equations and models for log interpretation
    • The fundamental techniques of log interpretation - a quick-look interpretation
