Decision support method for early-phase design of offshore hydrocarbon fields using model-based optimization
Gonzalez Rengifo, Diana Carolina; Stanko, Milan; Hoffmann, Arnaud (Journal article; Peer reviewed, 2019)This paper presents the development of a method to provide decision support in the feasibility studies and concept planning phases of oil and gas field development. The objective in developing the methodology was to provide ... -
Experiments and modelling of near-horizontal bubbly flow
Kjølaas, Jørn; Gonzalez Rengifo, Diana Carolina; Johansen, Krister Flåten; Schümann, Heiner (Peer reviewed; Journal article, 2023)This work aims to establish a fast and robust mechanistic model framework for predicting phase fraction profiles in bubbly flows. The main motivation is that the associated closure laws can in the future be used as a basis ... -
Modelling of dispersed oil/water flow in a near-horizontal pipe
Kjølaas, Jørn; Schümann, Heiner; Gonzalez Rengifo, Diana Carolina; Johansen, Stein Tore (Journal article; Peer reviewed, 2022)A gravity-diffusion model was implemented for predicting water concentration profiles in dispersed oil-continuous oil–water flows. In this model, the measured droplet size distributions were used instead of a droplet size ... -
Pipe flow experiments of unstable oil-water dispersions with three different oil viscosities: Flow pattern, pressure drop and droplet size measurements
Gonzalez Rengifo, Diana Carolina; Schümann, Heiner; Kjølaas, Jørn (Peer reviewed; Journal article, 2022)The transport of oil-water dispersions in petroleum production pipelines is difficult to predict and requires special attention since it affects the performance of the entire system. For future field developments it is ...
