In geothermal reservoirs, water and steam can flow simultaneously through the porous and permeable medium which the reservoirs consist of. This paper assesses the effects of both the initial condition of the fluid and of its flow direction on the relative permeabilities for a steady, one-dimensional two-phase flow of water and steam. The results show that for different types of relative permeability relations, these conditions can have a significant effect. Even when the mass fractions and conditions are identical for horizontal and vertical flow, the water saturation and consequently the relative permeabilities can vary significantly with flow direction and initial condition of the fluid. It emphasizes the importance of conducting further research in this area due to potential discrepancies between commonly used relations and actual flow behavior. Additionally, the paper describes a large-scale experiment being performed in a laboratory in Iceland, with the anticipated outcome of improved flow relations that can inform advanced modeling tools.
