An apparatus comprising:
- a downhole tool for a wellbore, the downhole tool having an elastomeric component comprising:
- an inside portion comprising a first elastomer;
- and
- an outside portion comprising a second elastomer different than the first elastomer, wherein the outside portion encloses the inside portion, and wherein the second elastomer is more chemically resistant than the first elastomer to fluids in the wellbore.
An apparatus comprising:
- a downhole tool for a wellbore, the wellbore configured to produce hydrocarbon, and the downhole tool having an elastomeric component comprising:
- an inside core enclosed by an outside cover, wherein the inside core comprises a first elastomer;
- and
- the outside cover comprising a second elastomer different than the first elastomer, wherein the second elastomer is more chemically resistant to fluids in the wellbore than is the first elastomer, and wherein elastomeric component comprises more of the first elastomer than the second elastomer.
A method of deploying a downhole tool into a wellbore, comprising:
- lowering the downhole tool into the wellbore, the downhole tool having an elastomeric component comprising:
- an inside core comprising a first elastomer;
- and
- an outside layer comprising a second elastomer different than the first elastomer, wherein the outside layer encloses the inside core, wherein the second elastomer is more chemically resistant than the first elastomer to fluids in the wellbore, and wherein the elastomeric component comprises more of the first elastomer than the second elastomer;
- and
- positioning the downhole tool at a target location in the wellbore.
