Description
Contenu

The textbook is addressed to students of applied geosciences and petroleum engineering.

Subject are the fundamental techniques of well logging/borehole geophysics and the interpretation of measured data (formation evaluation). Examples with an exercise part (sandstone reservoir, shaly sand interpretation, complex mineralogy of a carbonate reservoir) help to understand the different methods and algorithms.

The user will learn

  • reservoir properties (porosity, saturation, fluids, permeability, capillary pressure),
  • the physical background of well logging methods and the response with respect to reservoir characterization (physical principle, primary information from logs),
  • rules for optimal log combinations, basic equations and models, fundamental techniques of log interpretation.
