... ABSTRACT This paper presents a new method for severe slugging mitigation in pipeline-riser systems. It describes the use of an injectable venturi coupled to the pipeline-riser system upstream of the choke valve before the topside test separator for severe slug attenuation and system stability...

The modelling results are validated with data from a field-scale test well, with a total vertical depth of 880 m (2,880 ft.). From...

... frequently. The most recent technology in Shell for slug control is the Smart Choke. This technology consists of a single control valve that is installed between the riser top and the first stage separator. It is an active slug control device, and, therefore, continuous acting on changes in the flow of gas...
