Oil and gas reservoirs are tested by performing a shut-in test. A new down-hole shut-in valve has been installed in a multiphase flow loop and the pressure drop over the valve has been investigated for single phase and two phase flows. The flow path through the valve is a 3 meter long narrow channel, partially annular and partially circular, with several minor losses. CFD simulations of single phase liquid flow correspond well with experimental data. Two-phase pressure loss estimates based on common two-phase pressure loss multipliers are compared with experimental data. The absolute average percent error was 20–30% for some of the correlations.
