R & D
LedaFlow pursues research in co-operation with SINTEF. The goal is to ensure that the LedaFlow software has all the accuracy and features that are required to solve the challenges the oil companies have regarding multi-phase flow. KONGSBERG integrates the results from SINTEF into the LedaFlow software. This also involves development of apps so that trained users can access the advanced models that are in the core of LedaFlow. KONGSBERG and SINTEF work as an integrated team to take cutting edge research directly to the market. If you are interested in this or have ideas for what a good transient simulator tool like LedaFlow should contain please contact us and share your views.
Below, we will give a couple of examples of ongoing projects in LedaFlow Technologies and we will point out potentials for new projects we consider to launch.
Ongoing and completed R&D projects
- “The Ledaflow Wells Project”: Ledaflow Technologies initiated a R&D project in 2013 on vertical flows in risers and wells. To get the best results we needed better experimental data. A new experimental campaign was supported as an innovation project by The Research Council of Norway. The experiments were performed by SINTEF, and were completed in the autumn of 2015. The results from the experiments have already been used to develop model improvements. These are ready for commercial release in the LedaFlow 2.0 release in March 2016. We will continue to analyze the data and make more model updates based on this data set in the following LedaFlow releases.
- “1D Model improvements“: SINTEF and LedaFlow Technologies were able to access an extensive, high quality data set related to low liquid loading from Statoil. The data was used to initiate a model improvement project in late 2014. These improvements are included in the LedaFlow 2.0 release in March 2016 .
- “Solids transportation and deposition project“: In 2014 LedaFlow Technologies started a project to model wax and hydrates with SINTEF. This project had a high priority and we are proud to release the first set of models for Hydrates and Wax in the LedaFlow 2.0 release in March 2016. SINTEF and KONGSBERG have worked closely together to test the models to ensure they have high quality.
LedaFlow Technologies is proud to execute R&D activities in co-operation with SINTEF’s best researchers on multiphase flow. We find it motivating to see that our key people are awarded the prestigious price for outstanding research within SINTEF.
Upcoming and future research program
Below, are a couple of R&D projects alternatives that we are currently developing.
“Next generation 1D models”
is a new project initiative aimed at improving the models in LedaFlow, in order to increase the prediction accuracy of liquid amounts and pressure drop in oil and gas transport systems. The project will use experimental data from three-phase gas-oil-water flows in pipes. Good data on velocity profiles, local phase fractions and droplet sizes, will allow more rigorous and detailed closure laws. These will subsequently be implemented into LedaFlow. This will significantly improve the overall accuracy and the scaling abilities of LedaFlow – especially for three-phase flows.
is a concept based on operating within the hydrate domain while managing hydrate plug risk. This reduces the OPEX and CAPEX by decreasing the need to use traditional hydrate avoidance methods. The strategies used for hydrate management require control of the hydrate kinetics and hydrate wettability – factors deciding hydrate transportability. Pipeline hydrates can be characterized by an easily measurable parameter that reveals their tendency to plug or to be easily transported in the pipe. Solutions for controlled hydrate transport may be obtained by experimental tests, e.g. of a re-circulation scheme for seed hydrate particles. Wettability will also play an important role in hydrate adhesion to the pipe wall, and this can be studied experimentally.
