Abstract
A downhole tool comprising a body and a sealing element, wherein the sealing element is composed of a composite material comprising a rubber and a degradable acrylate-based polymer, and wherein at least a portion of the degradable acrylate-based polymer degrades when exposed to an aqueous fluid in a wellbore environment.
Claims20
A downhole tool comprising:
- a body;
- and
- a sealing element,
- wherein the sealing element is composed of a composite material comprising a rubber and a degradable acrylate-based polymer, and
- wherein at least a portion of the degradable acrylate-based polymer degrades when exposed to an aqueous fluid in a wellbore environment.
2 more elements
A method comprising:
- providing a downhole tool comprising a body and a sealing element, the sealing element being composed of a composite material comprising a rubber and a degradable acrylate-based polymer, and
- wherein at least a portion of the degradable acrylate-based polymer degrades when exposed to an aqueous fluid in a wellbore environment;
- installing the downhole tool in a wellbore;
- isolating a portion of the wellbore with the sealing element, the sealing element capable of holding a differential pressure;
- performing a downhole operation;
- and
- degrading at least a portion of the degradable acrylate-based polymer due to exposure to an aqueous fluid in the wellbore environment.
