Two-Phase Flow

Two-Phase Flow

A condition that is attained in production wells associated with high temperature (>200°C) geothermal reservoirs, wherein the flowing fluid comprises a mixture of steam and water. As the two-phase fluid depressurizes in the well, it expands causing it to accelerate upwards, negating the need for a pump to produce fluid.
