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.
