| titleOfInvention | Improved well sealing material and method of producing a plug |
| abstract | Bismuth-based alloys and the use of plugs made from such alloys to seal wells as well as the plugs themselves are provided. There is provided an alloy of bismuth, tin, and antimony comprising at least about 50% by weight bismuth, about 30 to about 35% by weight tin, and about 1.8 to about 2.8% by weight antimony; and an alloy of bismuth and silver comprising about 91 to about 97% by weight bismuth and about 3 to about 9% by weight silver. There is also provided a method for producing a plug comprising an alloy of bismuth, tin, and antimony; and a method for producing a plug comprising an alloy of bismuth and silver; wherein a length of a well is filled with the molten alloy and the molten alloy is allowed to solidify. |
