L51612 Seagull Shoreline System Flow Test-1987

A flow test was performed on the Seagull Shoreline System (SSS) and Enron's associated gas gathering system. The purpose of the flow test was to obtain field pressure drop and holdup data from a large diameter gas condensate pipeline. The validity of various two-phase correlations either proposed in the open literature or under development is generally established based upon comparison with field and/or laboratory measurements. Since accessible large diameter data is limited, most of these comparisons have been made with small diameter pipes. The application of the resulting correlations to actual large diameter pipelines has proven less than satisfactory in many cases particularly as regards holdup prediction. The objective of the flow test was to gather data in the mid-velocity range from a large diameter two-phase gas-condensate pipeline. The data, in particular pressure drop and holdup, will supplement the current PRCI data bank, which is used for correlation development and will add to the knowledge of two-phase flow in pipelines. This report presents the data along with its interpretation. In addition, comparisons are made with calculated results using PHE's two-phase flow computer program and associated correlations.
