Abstract
A wellbore isolation device comprising: one or more materials, wherein the one or more materials degrade after contact with a fluid; and a non-metallic coating, wherein the coating covers the one or more materials of the wellbore isolation device, and wherein the coating partially or wholly degrades after contact with a wellbore fluid. A method of removing the wellbore isolation device comprising: degrading the coating via contact with a wellbore fluid; and contacting the portion of the wellbore isolation device with a fluid, wherein the portion of the wellbore isolation device comprises one or more materials that degrade after contact with the fluid.
Claims19
A method of removing a wellbore isolation device comprising:
- degrading at least a portion of a non-metallic coating via contact with a wellbore fluid, wherein the coating covers at least a portion of the wellbore isolation device prior to contact with the wellbore fluid, and the portion of the wellbore isolation device is exposed to the wellbore fluid after degradation of the coating;
- and
- contacting the portion of the wellbore isolation device with a fluid, wherein at least the portion of the wellbore isolation device comprises a one or more materials that degrade after contact with the fluid, wherein the one or more materials comprise a degradable metal alloy, wherein the one or more materials comprises at least one degradable metal selected from the group consisting of aluminum, magnesium, and any combination thereof.
A wellbore isolation device comprising:
- a one or more materials that degrade after contact with a fluid, wherein the one or more materials comprises a degradable metal alloy, wherein the one or more materials comprises at least one degradable metal selected from the group consisting of aluminum, magnesium, and any combination thereof;
- and
- a non-metallic coating that covers the one or more materials of the wellbore isolation device, wherein the coating partially or wholly degrades after contact with a wellbore fluid.
A system for use in a wellbore penetrating a subterranean formation, the system comprising:
- a wellbore isolation device located within the wellbore and comprising at least a portion that comprises a one or more materials that degrade after contact with a fluid, wherein the one or more materials comprise a degradable metal alloy, wherein the one or more materials comprises at least one degradable metal selected from the group consisting of aluminum, magnesium, and any combination thereof;
- and
- a non-metallic coating that covers the at least a portion of the wellbore isolation device, wherein the coating partially or wholly degrades after contact with a wellbore fluid.
