In oil/water flows with very low water rates, the steady-state water fraction jumps discontinuously from a low value to a high value when the oil rate falls below the critical value. This jump is understood to be connected to the existence of multiple solutions, and generally takes place when the...

A comprehensive three-phase flow campaign, funded by Equinor as part of the Tanzania gas field development project [1] [2] [3], was carried out in the SINTEF Large Scale Loop at Tiller in 2017-2018. The experiments were conducted in a 94 meter long 8" pipe, with 2.5° inclination at 60 bar nominal...

At high gas rates, even small amounts of liquid can have a significant impact on the pressure drop, and this is important to model accurately when designing wet gas transport systems. In order to gain an improved understanding of this matter, several sets of two- and three-phase experiments in low...

As presented earlier at the OFCS [1], a specific Cold Flow concept has been developed and tested under high-pressure laboratory conditions, building on the realisation that precipitation phenomena in multiphase production flows may be controlled through use of a recirculation seeding and cooling...
