Abstract
This chapter deals with the basic equations for the flow of liquid through porous media along with solutions of interest for various boundary conditions and reservoir geometry. These solutions are required in the design and interpretation of flow and pressure tests. The applicable equations for liquid flow are presented in this section, including pressure transient behavior with dimensionless pressure solutions for the specific conditions. Some important dimensionless functions are presented and references to others are provided. The dimensionless pressure approach provides a way to calculate pressure response and to develop techniques for analyzing transient tests in a variety of systems. This book describes steady-state, pseudo-steady-state, and unsteady state flow equations including oil radial diffusivity equation, basic oil flow equations, and various dimensional flow geometries. This chapter discusses the basic flow theory for oil well testing and analysis techniques. A general equation is used for transient pressure behavior with dimensionless pressure solutions desired. This chapter also presents unsteady-state pressure distribution calculations in directional oil wells.
