Abstract
A downhole sealing device, a well system employing a downhole sealing device, and a method for sealing within a wellbore. The downhole sealing device, in one aspect, includes one or more downhole sealing features, and an elastomeric element comprising a thiourethane/acrylate polymer coupled to the one or more downhole sealing features. In at least one aspect, the elastomeric element is operable to be compressed in a downhole application against a tubular as a seal.
Claims29
A downhole sealing device, comprising:
- one or more downhole sealing features;
- and
- an elastomeric element comprising a thiourethane/acrylate polymer coupled to the one or more downhole sealing features, the elastomeric element operable to be compressed in a downhole application against a tubular, wherein the elastomeric element is a 3D printed element manufactured using a VAT resin formed using a liquid mixture including:
- a crosslinking component;
- at least one monomer and/or oligomer;
- and
- a chain transfer agent comprising at least one of a thiol, a secondary alcohol, and/or a tertiary amine, wherein the resin is configured to react by exposure to light to form a cured solid material.
A well system, comprising:
- a wellbore located in a subterranean formation;
- and
- a downhole sealing device positioned within the wellbore, the downhole sealing device including:
- one or more downhole sealing features;
- and
- an elastomeric element comprising a thiourethane/acrylate polymer coupled to the one or more downhole sealing features, the elastomeric element operable to be compressed against a surface in the wellbore, wherein the elastomeric element is a 3D printed element manufactured using a VAT resin formed using a liquid mixture including:
- a crosslinking component;
- at least one monomer and/or oligomer;
- and
- a chain transfer agent comprising at least one of a thiol, a secondary alcohol, and/or a tertiary amine, wherein the resin is configured to react by exposure to light to form a cured solid material.
A method for sealing within a wellbore, comprising:
- positioning a downhole sealing device within a wellbore located within a subterranean formation, the downhole sealing device including:
- one or more downhole sealing features;
- and
- an elastomeric element comprising a thiourethane/acrylate polymer coupled to the one or more downhole sealing features, wherein the elastomeric element is a 3D printed element manufactured using a VAT resin formed using a liquid mixture including:
- a crosslinking component;
- at least one monomer and/or oligomer;
- and
- a chain transfer agent comprising at least one of a thiol, a secondary alcohol, and/or a tertiary amine, wherein the resin is configured to react by exposure to light to form a cured solid material;
- and
- subjecting the elastomeric element to an axial compressive force, the axial compressive force compressing the elastomeric element against a surface in the wellbore.
