... liquid content remains close to the low liquid content equilibrium. This work studies an undulated 120-mile long and 32-inch ID gas pipeline operated at a relatively low flowrate, corresponding to gas velocities below the critical velocity. A transient multiphase flow simulator is used to model...

For simulations of hydrate-forming oil-dominated flows in an experimental flow loop, the hydrate cut, subcooling, slurry viscosity and water...

... The use of sphering for liquid management is widely employed on gas condensate export pipelines. Field data for routine ‘undersized’ sphering operations of a 20" gas condensate pipeline was analysed, and OLGA (v2015.1.1 & v2017.1.0) simulations set up to try and match the displaced surge...

... DATA COMPARISON The experiments are simulated using the OLGA-S HD 2016.1 point model. Two key uncertainties need to be addressed when comparing these simulations against the measurements. First, the simulations are based on the stated mixture velocities rather than those obtained by integrating...

... Turbulent Poiseuille flow of two immiscible liquid layers inside a rectangular channel has been performed adopting a Direct Numerical Simulation of wall bounded flow, coupled with the Phase Field Model (PFM). A thin liquid layer flows on top of a thick liquid layer, their thickness ratio is h 1/h 2 = 1/9...

..., and the other riser accumulates liquid. This unequal split is unwanted from the operational point of view, as it leads to a larger pressure drop over the risers and liquid accumulation in one riser. The instability is also studied in a design study of a gas-condensate field with 1D simulations. It is shown...

Therefore, it appears that the presence of a small amount of liquid in this geometry reduces the peak value of measured erosion. Computational Fluid Dynamics (CFD) simulations are also...

Wax deposition was observed in two wells while no wax deposition was seen in other wells in the same field. To understand the underlying mechanisms 18 different production scenarios were simulated using...
