Petrophysics: Theory and Practice of Measuring Reservoir Rock and Fluid Transport Properties, Fifth Edition is a seminal text on the field that delivers information for reservoir engineers, production engineers, and geoscience students who need to understand rock-fluid interactions in order to maximize reservoir performance and minimize emissions and environmental impacts. This new edition lays a foundation to petroleum geology, including an overview of pre- and post- carbon emission concerns, porosity and permeability, formation resistivity and water saturation, capillary pressure, wettability, applications of Darcy's Law, naturally fractured reservoirs, stress effects on reservoir rock, reservoir characterization and well logs, and more. Each chapter synthesizes relevant theory, studies and advances, methods, procedures, calculations, definitions, exercises and assignments designed to reinforce learning.
