This text investigates the fundamental physical properties of reservoir rocks and fluids required to quantify hydrocarbon reserves and predict flow behavior. The authors, established experts in petroleum engineering, synthesize decades of laboratory data and theoretical fluid mechanics to provide a rigorous framework for reservoir characterization. The book establishes the mathematical and physical basis for understanding how porous media interact with oil, gas, and water under varying pressure and temperature conditions.

Industry professionals and academics frequently cite this work as a foundational text for understanding the physical behavior of reservoir systems. It is widely regarded as a standard reference for students and engineers seeking a deep technical understanding of fluid-rock interactions.
