A packer system for a wellbore. The system includes a base packing element mounted to an inner surface of a first tubular and an actuator which actuates the base packing element in a radially inward direction. The system further includes a first trigger element disposed at the inner surface of the first tubular and operatively connected with the actuator, and a second trigger element disposed at an outer surface of a second tubular. The second tubular is displaceable in an axial direction with respect to the first tubular, wherein, upon displacing the second tubular at a predetermined position within the first tubular: the second trigger element engages with the first trigger element; and the first trigger element causes the actuator to actuate the base packing element in a radially inward direction, to bridge a space between the first tubular and second tubulars. Also disclosed and described is a related method.

A backup including a gage ring having frustoconical surface and a groove in the frustoconical surface, a segment having a nose engaged with the groove, the segment having an overlap finger and a finger receptor, a wedge ring in contact with the segment, and a retainer member disposed to retain the segment. The downhole tool further comprising a second backup also adjacent the element and spaced from the first backup by the element. A borehole system including a borehole in a subsurface formation, a string dispose within the borehole, a backup disposed within or as a part of the string. A borehole system including a borehole in a subsurface formation, a string dispose within the borehole, a tool disposed within or as a part of the string.

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.

This disclosure may generally relate to additive manufacturing operations and, more particularly, to systems and methods for three dimensional (3D) printing a sealing element. Specifically, examples of the present disclosure may be implemented to manufacture a sealing element which may be disposed in a wellbore to seal off a portion of a well.
