Abstract
Slugging involves a fluctuation of gas phase in pockets and liquid phase surges. As a result, the flow is uneven, and its presence is undesirable. It is common to have severe slugging in the co-current flow of gas-liquid multiphase stream in pipeline-riser systems, which manifests as a substantial fluctuation in flow rate and pressure. It might harm topsides equipment used in processing the multiphase stream. Severe slugging, a type of slugging that typically takes place at the base of the riser column, results in huge amplitudes in the pressure variation within the riser column, which harms equipment that is installed topside. Also, severe slugging can give rise to 50% drop in production ; causing a significant problem for the oil and gas industry.In order to better predict it, its properties (slug frequency, length, translational velocity, and liquid holdup), there is an urgent need to better understand the mechanism of severe slugging and ability to model the scenario properly . This study aggregated recent research works on the various severe slugging mitigation techniques and provided a table for comparison of the technical challenges associated with the key severe slugging mitigation techniques especially in deepwater oil field scenarios. The table of comparison could serve as a preliminary design guide at Pre-FEED design stage in deepwater oil field development. This review study also highlighted the conditions leading to severe slugging formation in deepwater oil field scenarios and made recommendations for further studies.
