Kongsberg Oil & Gas Technologies has released ‘LedaFlow’, the fruit of a decade long collaboration between Total, ConocoPhillips and Norway’s Sintef R&D unit. Kongsberg UK MD Mike Topp said, ‘Ledaflow was developed to fulfill market demand for improved dynamic multiphase flow simulation, particularly in offshore production from complex, deepwater and Arctic environments with multiphase transport and long tie-backs.’
LedaFlow adds fine grained physico-chemical dynamic modeling of flowline behavior to Kongberg’s K-Spice dynamic process simulator. K-Spice is an integrated asset modeling solution that is used to design and monitor the complete facility from wells, flowlines, subsea processing, risers, onshore & offshore processing to export. LedaFlow models water and oil dispersions and gas bubbles in liquid phase. It also allows for modeling of 3-phase flows with solid particles such as sand and hydrates.
LedaFlow has been calibrated in extensive field trials at Sintef’s multiphase flow laboratory in Trondheim, Norway. Here, Sintef’s ‘Tilda’ test data set was augmented with new experimental data on novel geometries and configurations. These include up to 12” diameter flowlines operating at 90 bars and different combinations of multi-phase flow of gas, oil, water and particulate matter in transport. Consortium partners ConocoPhillips and Total have also validated LedaFlow against data from their operated fields covering gas/condensate and oil dominated systems and a range of pipe diameters.
Kongsberg’s simulator clients include BP, which used the toolset in an operator training simulator for its Angolan Greater Plutonio development and Statoil, which has built a dynamic production model for its Snøhvit field in the Barents Sea. In all, 80 Konsberg simulation solutions have been implemented world-wide. More from www.oilit.com/links/1005_4.
