Slugging flow is a condition caused by a liquid obstruction at the riser base. It exhibits cyclic
behaviour. The cycle consists of a protracted time of no gas production at the riser's top …

Severe slugging poses an enormous threat to the safe operation of high-pressure long
petroleum pipelines. However, most published studies are conducted in short pipelines …

Real-time optimization with persistent parameter adaptation (ropa) is an rto approach, where
the steady-state model parameters are updated dynamically using transient measurements …

The level of flow assurance for gas-liquid two-phase pipeline-riser system in offshore oil and
gas fields will be significantly improved once the transition to undesirable flow patterns can …

In order to develop the transition models for undesirable two-phase flow regimes in a
pipeline-riser system in offshore oil and gas production systems, the relation between the …

As an offshore oil well ages, it is common for the production system to face multiphase flow
problems such as limit cycles. This phenomenon, known as slugging in the jargon of the oil …

Severe slugging produces huge fluctuations of pressure and flow rate, which is often
eliminated by choking because of its easy operation and good performance. However, most …

The dynamic behavior of an offshore oil production plant obtained through an anti-slug
scheme based on a feedback PI control was studied. Three different SISO control scenarios …

The accurate measurement of mass flow rate is of vital importance with respect to production
control in gas or oil fields equipped with chokes. A theoretical model to predict the flow …

The limit cycle is an unexceptional problem in the oil industry that may cause significant
losses in production. Also called slug flow or slugging, the unsteady flow can be handled by …
