Abstract
Downhole tools comprising a body, wherein at least a portion of the body is degradable when exposed to a wellbore environment; and at least one oil-degradable sealing element composed of an oil-degradable elastomer, wherein the oil-degradable sealing element degrades in the wellbore environment. The oil-degradable elastomer is selected from the group consisting of an oil-degradable natural rubber, an oil-degradable synthetic rubber, and any combination thereof.
Claims28
A downhole tool comprising:
- a body, wherein at least a portion of the body is degradable when exposed to a wellbore environment;
- and
- at least one oil-degradable sealing element composed of an oil-degradable elastomer, wherein the oil-degradable sealing element degrades in the wellbore environment.
A method comprising:
- installing a downhole tool in a wellbore, wherein the downhole tool comprises a body and at least one oil-degradable sealing element composed of an oil-degradable elastomer, and
- wherein at least a portion of the body is degradable when exposed to the wellbore environment and the oil-degradable sealing element degrades in the wellbore environment;
- fluidly sealing two sections of the wellbore with the oil-degradable sealing element of the downhole tool, the oil-degradable sealing element capable of holding a differential pressure;
- performing a downhole operation;
- and
- degrading at least a portion of the oil-degradable sealing such that the oil-degradable sealing element no longer is capable of holding the differential pressure.

A system comprising:
- a wellbore;
- and
- a downhole tool capable of being disposed in the wellbore to fluidly seal two sections thereof, the downhole tool comprising a body and at least one oil-degradable sealing element composed of an oil-degradable elastomer and the oil-degradable sealing element is capable of holding a differential pressure,
- wherein at least a portion of the body is degradable when exposed to the wellbore environment and the oil-degradable sealing element degrades in the wellbore environment.
