represented by double porosity theory. The function of shape factor is to define
the leakage term between the matrix block and fracture conduits. Different geometric
assumption of the double porosity medium resulted in different shape factors
and consequently the leakage term. The influence of various shape factors based
on different geometric assumptions on their matrix-fracture transfer rate has
been studied in this study. Comparison of different shape factor performance
is accomplished via the dimensionless pressure and time. This study proposed
a new relation that measures the impact of different shape factor in the consequence
flow rate in fractured reservoir. It was discovered that higher value of shape
factor contributes to higher rate of change of flow rate. This correlation can
aid in deciding the appropriate shape factor for modeling double porosity medium.]]>Almengor, J.G., G. Penuela, M.L. Wiggins, R.L. Brown, F. Civan and R.G. Hughes,20022002Barenblatt, G.I., I.P.
