A mechanistic model of gas-condensate flow in pores

M Jamiolahmady, A Danesh, D H Tehrani and D B Duncan


Abstract

Recent experimental results reported in the literature indicate that the relative permeability of gas-condensate systems increases with rate (velocity) at some conditions. To gain a better understanding of the nature of the flow and the prevailing mechanisms resulting in such behaviour, flow visualisation experiments have been performed, using high pressure micromodels. The observed flow behaviour at the pore level has been employed to develop a mechanistic model describing the coupled flow of gas and condensate phases. The results of the model simulating the observed simultaneous flow of gas and condensate pases have been compared with reported core experimental results. Most features of the reported rate effect are predictable by the developed single pore model, necertheless, its extension to include multiple pore interation is recommended.
