..., however, can lead to wasted CAPEX and/or OPEX, and may not work for economically challenged/ marginal projects. To address this problem, we have built a large-scale flow loop (4" pipe ID, and 120 ft long test section) for testing wax deposition. A variety of experiments were performed changing...

... ABSTRACT An experimental two-phase flow campaign with a viscous oil (100 cP) was conducted in the Large Scale 8" loop at the SINTEF Multiphase Flow Laboratory. The loop consisted of three main test sections, with pipe inclinations 0, 0.5 and 90 degrees, and with approximate lengths of 380 m...

Experimental results indicated that slug length in the vertical and lateral sections of a well present values...

... Abstract Pressure gradients of concurrent upward air-water flow have been measured in a 25.4mm internal diameter vertical test section over a range of superficial air and liquid velocities. Several sub-regimes of annular flow (pulse/disturbance wave, ripple wave, partial wetting, and rivulet...
