CFD modeling of gas-liquid cylindrical cyclones

The Gas-Liquid Cylindrical Cyclone (GLCC) is one of the main alternative of conventional vessel-type separators of a two-phase gas-liquid mixture, since it is more compact, simple and has a lower footprint. The main objective of this study is to use CFD modelling, in  STAR-CCM+® software using VOF model, in order to evaluate the effect of geometrical modifications in the reduction of LCO and GCU.

Slug flow study along different well trajectories

Gas-liquid slug flow is one of the most common multiphase flow patterns in oil and gas production. This has a dynamic behavior that can be predicted using the slug frequency and slug length. Based on the values of these parameters, different operational problems can be observed such as poor reservoir inflow, additional downstream/upstream equipment requirements and increase operational costs. Previous studies have established relations between these parameters and operating conditions such as liquid/gas flow rate, inclination angle and pipe diameters in horizontal pipes.
