... 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...

... in this study. The LAGL technique uses a liquid-gas mixture to unload wells and initiate gas-lift, rather than the industry standard practice of installing multiple unloading mandrels and valves. The intent of the modelling presented in this work is to validate experimentally and to analyse some of the key...

... with active by-pass control has been designed, fabricated and subsequently tested on a laboratory scale. The experimental setup consists of a 52 mm diameter pipe with a length of 62 meter. The working fluid is air. The speed controlled pig has an adjustable by-pass valve which can provide the right amount...

.... The upstream section is modelled in a single LedaFlow model. The wellhead is modelled using a valve where the valve position is set using a conductance table. The well section of the model has a temperature boundary condition with an imposed temperature gradient based on the region ground properties. 494 © BHR...

... 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 and liquid by manipulating the opening of the control valve.

The density wave instability, on the other hand, is relatively unexplored. The goal of the present research was to understand the mechanism that causes the density-wave...
