Abstract:
A plug for Plug and Abandonment (P&A) operations and methods of use are described. The plug comprises a bismuth-based alloy and resin, allowing for sealing of an oil well using two different mechanisms with a shorter plug.

Claim (Index 1):
A method of plugging a well during plug and abandonment operations, comprising:\n a) deploying a first tool downhole to remove or open or perforate both an inner tubular and exterior casing at a section of well to be plugged; b) deploying a second tool downhole having an optional base, a sleeve erected thereon for holding a heater, a heater and an alloy, wherein said alloy is stored above said base and around an outside of said sleeve; c) heating said eutectic alloy with said heater to form a molten alloy; d) allowing said molten alloy to expand and solidify to form a cast-in-place metal plug that fills at least part of said section of well to be plugged; e) optionally adding additional eutectic alloy to said well and repeating steps c-d until a predetermined height of cast-in-place metal plug is formed; f) removing said heater but not said sleeve; g) deploying or pouring a resin downhole on top of said cast-in-place metal plug; and, h) curing said resin to form a resin plug, wherein said cured resin adheres to said cast-in-place metal plug, further wherein the cure resin covers said cast-in-place metal plug and said sleeve of said second tool; and i) wherein said cast-in-place metal plug and said resin plug together form a single two-material plug.
