... and thermodynamic wax models may affect the predictions of wax deposition rate and pigging frequency. The fluid flow models considered include the steady-state multiphase OLGAS® and Beggs-Brill model. The thermodynamic wax models of Coutinho and an ideal mixing approach will be compared. Real field cases...

... oil and coolant temperatures. The measured data were compared with computational simulations using both OLGA and WAXPRO, software developed by TUPDP. OLGA and WAXPRO are tuned using the flow loop data, thereby, lowering the uncertainty in predictions and increasing the project reliability...

... 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...

... (Exxsol D80) and a high (Nexbase 3080) viscosity oil and SF6 gas were compared with OLGA point-model simulations. Good agreement was found for Exxsol D80 pressure drop and holdup, although OLGA overpredicted slug flow. For Nexbase 3080 OLGA predicted slug flow for most data points observed as stratified...

... predictions using the OLGA2000 steady state code, OLGAS (version 3.02). Results from the model comparison indicate that the model under-predicts both water accumulation and frictional pressure drop, particularly at high inclinations. 1 INTRODUCTION In the oil and gas industry, multiphase flow occurs...
