- Oil leaks from abandoned deep sea water wells create major environmental impacts. BiSN-UK has devised a new technology for sealing oil wells using heat from a thermite alloy to melt a bismuth alloy that flows between a plug and the well bore before solidifying into a pressure resistant seal. This paper describes how the phase change and flow of the bismuth alloy were simulated using an explicit/implicit finite element methods and validated with experimental data. The proven numerical methods were used by BiSN-UK to verify the geometrical and chemical parameters of the bridge-plug to be used prior to deployment.
