<p>Well productivity is one of primary concerns in field development and provides the basis for field development strategy. The primary focus of this book is to derive productivity formulae for oil wells in anisotropic reservoirs using straightforward mathematical techniques. Pressure transient analysis methods presented in this book are based on analytical solutions of the various forms of flow equation. It is the authors' opinion that the distinct advantage of the analytical methods is in their simplicity and the ability to identify correctly the main physical features of a given system. The analytical approach should be considered as an initial and necessary step by which the system is identified and first estimates of parameters are obtained. This book is arranged so that it can be used as an engineering mathematics textbook for graduate students in petroleum engineering, and can help the students have a complete understanding how mathematics can solve complex problems in reservoir engineering. This book is also a reference book for research scientists in petroleum industry and practicing reservoir engineers.</p>

<p>Well productivity is one of primary concerns in field development and provides the basis for field development strategy.Petroleum engineers often relate the productivity evaluation to the long-time performance behavior of a well, that is, the behavior during pseudo-steady state or steady state flow. This book examines the production performance of oil wells with constant flow rates in different shapes of anisotropic reservoirs, a library of new productivity equations is provided. Wells may be located arbitrarily in an anisotropic reservoir, several combinations of closed and/or constant pressure boundary conditions are considered at vertical and lateral reservoir boundaries. The effects of permeability anisotropy on well performance are discussed. Convenient algorithms to calculate shape factor and pseudo skin factor due to partial penetration are provided. Comparison of different drive mechanisms is presented. Influence of reservoir boundaries on the well responses is investigated. The proposed equations in this book can be used to determine the economical feasibility of drilling a well.</p>
