LedaFlow validation
The validation of the LedaFlow® results against field and experimental data has been paramount in the development. The key for the development of LedaFlow was therefore access to new large scale experimental data to compare the results with. Continuously during the development of LedaFlow, results have been compared with the complete set of available experimental data and compared with available field data from the LedaFlow partners ConocoPhillips and TOTAL.
The latest results and conclusions about the validation of LedaFlow can be found in the following two papers:
ABSTRACT
Two commercial multiphase pipe flow simulators, OLGA® 5.3 and LedaFlow® 1.0 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 and a relative error up to 70% on the pressure-gradient in
intermittent flow. Two field cases, one oil-dominated and the other gas-dominated, have
been tested. The predictions show very good agreement with the available field
measurements of pressure drop and temperature. In the gas-condensate case, similar
turndown and liquid accumulation curves are obtained. |

Each new version of LedaFlow is compared against a large set of experimental and field data to verify the impact of code changes when implementing new versions.
