Abstract:
Multiphase flow through horizontal/inclined pipeline network is the most commonly
encountered fluid flow in upstream oil and gas industry. Multiphase flow is highly
complicated and unpredictable especially during pigging operations. Tremendous changes
in the flow regimes due to flow and terrain induced slugs and phase separation makes the
flow phenomenon highly complex to predict without rigorous theoretical/empirical
modeling. Effective removal of wax and accumulated water from pipelines without
production loss and process upset is the real challenge for Production Engineers. Software
simulation models and empirical equations based on experimental results helps engineers
to assess the risk involved and choose the most suitable pigging solution for multiphase
pipeline cleaning operations
