Investigating the properties of bismuth alloys in well completion and well plugging

This  PhD research work focuses on the investigation of alternative - to cement - materials for P&A operations. Bismuth alloys seem to be promising materials for this area and therefore research is needed to support this claim. Investigation of the properties of the alloy, the effect of temperature and pressure on the alloy's microstructure and the interaction between the BiSn alloy, the casing steel and the surroundings/formations, are some of the topics of this Ph.D. work.
