Abstract
Downhole tools including a body, wherein at least a portion of the body is degradable when exposed to a wellbore environment; and at least one degradable sealing element comprising a cast degradable elastomer, wherein at least a portion of the cast degradable sealing element degrades when exposed to the wellbore environment.
Claims27
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 degradable sealing element disposed on the body, the at least one degradable sealing element comprising a thermoset cast degradable elastomer, wherein at least a portion of the thermoset cast degradable sealing element degrades when exposed to the wellbore environment.
A method comprising:
- installing a downhole tool in a wellbore, wherein the downhole tool comprises a body and at least one degradable sealing element comprising a thermoset cast degradable elastomer disposed on the body, and
- wherein at least a portion of the body and the degradable sealing element are degradable when exposed to a wellbore environment;
- fluidly sealing two sections of the wellbore with the degradable sealing element of the downhole tool, the degradable sealing element capable of holding a differential pressure;
- performing a downhole operation;
- and
- degrading at least a portion of the degradable sealing element such that the 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 degradable sealing element disposed on the body, the at least one degradable sealing element comprising a thermoset cast degradable elastomer and the degradable sealing element capable of holding a differential pressure,
- wherein at least a portion of the body and at least a portion of the degradable sealing element are degradable when exposed to a wellbore environment.
