This project will study the fundamentals of rate-dependent, mass transfer between gas and oil in porous media, using network modelling. An understanding of the pore-scale mechanisms of mass transfer in the presence of pore-scale heterogeneity will enable the development of improved, large-scale models of compositional processes in hydrocarbon reservoirs. These processes include miscible and near miscible gas injection, improved simulation of which is one of the key technologies (identified in Foresight) that have the potential to meet the Energy Foresight target to increase yields from existing hydrocarbon reservoirs . It is clear that large scale, finite difference simulations make incorrect assumptions about the small scale flow physics. However, to date, no attempt has been made to predict numerically the phase behaviour associated with miscible/near miscible flow on the pore-scale, although network modelling has been used successfully to predict immiscible displacement behaviour for two and three-phase flow. The aims of this work are to- develop a better understanding of miscroscopic sweep efficiency during miscible/near-miscible gas-oil displacements in porous media- obtain a better quantification of physical diffusion and dispersion in heterogeneous porous media- improve the bulk description of miscible and near-miscible flow by developing effective flow properties from pore-scale simulation
