A downhole tool for a wellbore in geothermal service, the downhole tool having a component comprising a blend of ethylene propylene diene monomer (EPDM) and silicone, wherein the blend is vulcanized.
A method comprising:
- preparing a component for a downhole tool for a wellbore in geothermal service, wherein the preparing comprises:
- blending ethylene propylene diene monomer (EPDM) and silicone to give a first blend;
- blending an additive with the first blend to give a second blend;
- molding the second blend to form the component;
- and
- vulcanizing the EPDM and the silicone in the second blend during molding the second blend to form the component.
3 more elements
A method of deploying a downhole tool into a geothermal wellbore, comprising:
- lowering the downhole tool into the geothermal wellbore, the downhole tool having a component comprising a blend of ethylene propylene diene monomer (EPDM) and silicone, wherein a weight ratio of the EPDM to the silicone is in a range of 5:95 to 40:60, and wherein the EPDM and the silicone are vulcanized;
- and
- positioning the downhole tool at a target location in the geothermal wellbore.
