摘要

A method of performing an operation in a wellbore comprising: introducing a tool into the wellbore, wherein the tool comprises: (A) a mandrel comprising a port; and (B) a plug, wherein the plug is located within the port, and wherein the plug comprises at least a first material, wherein the first material partially or wholly dissolves via corrosion; introducing a cement composition into an annulus located between the outside of the tool at least at the location of the port and the inside of the wellbore; and causing or allowing at least a portion of the first material to dissolve, wherein the step of causing or allowing is performed after the step of introducing the cement composition.
