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.
