Condensation and flow experiments were conducted at subsurface conditions in a glass micromodel using reservoir fluids with and without the hydrogen sulfide component. It has been noted that the formation of the condensing phase as well as modes of condensate flow are similar for both fluids. Furthermore, an additional condensate transport mechanism, termed lamella Row, was observed with the sour fluid. It has been concluded that core Row experiments conducted with sweet reservoir fluid should reproduce the flow of sour fluid to a large extent.
