Abstract

Permeability distribution of the rock is of utmost importance while creating a dynamic reservoir model. However, in the absence of any continuous permeability log, the input for this purpose either comes from well test or from core information or from some popular porosity-dependent transform. While the information from well test is on a large scale, the one from core is on a very small scale. Hence neither of these two gives the permeability at an intermediate scale. On the other hand, the porosity-based transforms do not take into consideration the pore size and its distribution, which play an equally important role while deciding the permeability of dynamically connected pores
