... in the industry, on an extended set of field data from a large gas-condensate pipeline with three-phase flow. A steep escarpment strongly influences the dynamics of pipeline pressure, and liquid content and outlet rates; production rates span the region of transition between separated and slug flow regimes. ‘Out...

... ABSTRACT Low liquid loading conditions in wet gas pipelines are challenging to characterize due to a lack of high quality field data and potential for multiple numerical holdup solutions. Recently, experimental and modelling activities have been conducted to improve the accuracy of multiphase...

... Abstract This paper presents a comparison between field data from a West Africa deep offshore field operated by TOTAL and software available for design engineering. Multiphase flow simulations have been performed for several production loops to evaluate the software ability to reproduce steady...

Therefore, understanding the accuracy and capability of these models, validating and improving them against the field data are of great importance for the daily operations support and future project design. This study evaluated the accuracy of a transient multiphase flow simulator in modeling...

... ABSTRACT The present work investigates the ability of the available 1D multi-phase flow simulators MAST [1] and OLGA [2] to reproduce measured field data on the offshore Heidrun oil field located in the North Sea. The production is tied back from two subsea templates through two 5km long 10...

... ABSTRACT Two commercial multiphase pipe flow simulators, OLGA®5.3 and LedaFlow®, have been tested on laboratory and field data. Regarding the laboratory data, the results are comparable, however, two weak points have been identified: an overprediction of the liquid hold-up in stratified flow...

... hydrodynamic slugs are generated in upward inclined sections, where transition from stratified to slug flow occurs, referred to a flow map, and grow large in the downstream stratified section. The field data are attempted to be reproduced by means of dynamic simulations. The discrepancies between the data...
