This fifth part of a work on naturally fractured reservoirs deals with the predictions of secondary oil recovery. It is stated that a conventional material balance is valuable to predict the secondary oil recovery from naturally fractured reservoirs, provided that curves of relative permeability of the matrix-fracture system are used. A graph of the recovery factor vs. pressure as a function of the conformation factor can be used to estimate the oil recovery. As the value of the conformation factor decreases, the oil recovery also decreases. Another way to calculate the secondary oil recovery is through the use of equations which include the effect of the vertical efficiency in naturally fractured reservirs. Several graphic solutions to determine the oil recovery due to imbibition in these kind of reservoirs have been published. Those graphic solutions, as well as the equations to predict the secondary oil recovery in naturally fractured reservoirs, are presented.
