In today’s world, increasing demand of energy has forced Petroleum Companies to search
different ways to increase their production. Therefore, Petroleum companies test wells which
take longer time and they try to find out the most economic production scenarios to increase
the oil/gas production of the wells. As a result, modelling the reservoir as realistic as possible,
determining the performance of reservoirs and the productivity of wells are more important. In
this work, we present productivity index equations for vertical and horizontal wells, productivity
in homogeneous, isotropic or anisotropic closed reservoirs and couple them with a tank model
for performance prediction. By using the model developed during the course of this work, we
compare the results for different well and reservoir types. The results show that the models
presented in this work provide a simple, yet quite accurate performance predictions for vertical
and horizontal wells producing in isotropic/anisotropic single or double porosity reservoirs.
