Complex interpretation of various petrophysical data increasingly applies theoretical models. In this course we study some of the fundamental concepts (Bound models, inclusion models for isotropic and anisotropic media, capillary models, Gassmann model) with respect of the physical assumptions, the conditions and restrictions of an application. For the models excel-worksheets are prepared in order to work with experimental data and discuss practical aspects of implementation in interpretation workflows.
This interactive training course will feature
A brief refreshing presentation of petrophysical key properties (e.g. porosity, saturation) and their correlation with measured parameters (e.g. resistivity, wave velocities)
Systematic presentation of fundamental model concepts (simple averaging models, Hashin bounds, sphere pack models, capillary models, inclusion models) and their assumptions and conditions for application)
Demonstration of various models (using practical excel exercises); application on real data sets
Calculation of selected interpretation charts and templates
Discussion of preferred possibilities of implementation in practical algorithms
Course Level: Foundation Instructor: Jürgen Schön
Designed for you, if you are...
A geophysicist/petrophysicist, geologist, petroleum or reservoir engineer involved in geophysical data interpretation directed on rock properties
Working on development of interpretation algorithms and techniques for conventional or unconventional rock types/reservoirs
Interested in a physical background in petrophysics and development of model based algorithm
How we build your confidence
This course will give a presentation of fundamental model concepts and the formulation of final equations using prepared Microsoft Excel-worksheets. You will then discuss the function of the individual input parameters with respect to an integrated rock characterisation. On real data sets different models are applied and evaluated.
The course is based on the textbook and implemented Excel worksheets written by the instructor: Physical Properties of Rocks – Fundamentals and Principles of Petrophysics, 2nd Edition, Schön, J.H., 2015, Elsevier B.V., Amsterdam.
This textbook gives the detailed description, primary references and some additional aspects of application and implementation in interpretation techniques. Textbook and all Excel worksheets are part of the course material for each participant.
