    • A device and a method for a field expansion. A support core (30) is inserted into the device by a field expansion apparatus.

The device comprises an elastomeric tubing (10) and an adapter (40). The elastomeric tubing (10) has a forward end opposite a rearward end and an axial bore extending therethrough configured to receive the support core (30). The adapter (40) has a step portion (41) defined by a radial outer surface (42) and a flat surface (43) radially outwardly extending from the radial outer surface (42), and an axial bore (44) extending therethrough. The axial bore (44) has a diameter substantially the same as the diameter of the axial bore (12) of the elastomeric tubing (10). The adapter (40) is positioned substantially coaxially with the elastomeric tubing (10) between the pressure applying means (20) and the elastomeric tubing (10) such that, in response to inserting the support core (30) from the rearward end into the elastomeric tubing (10), the flat surface of the adapter (40) is pushed against the flat surface of the pressure applying means (20) by the elastomeric tubing (10); the interface between a rearward end of the adapter (40) and the forward end of the elastomeric tubing (10) is of high friction so that the adapter (40) and the elastomeric tubing (10) expand radially in unison, and the radial outer surface of the adapter (40) exerts a radially outward pressure against the radially expandable inner surface of the pressure applying means (20). device and method for field expansiondevice and method for field expansion

    • A device for contracting a pre-expanded polymer material comprises a base comprising a thermally conductive material. The device further comprises a heat transfer body coupled to the base, where the heat transfer body comprises a thermally conductive material, and where the heat transfer body includes a trough configured to receive and transfer heat to a pre-expanded polymer material disposed in the trough. Through the use of the activating/contacting device, a field technician can utilize a portable oven as a heat source, and avoid the need to use a conventional hot air gun or heat ring. In addition, the activating/contacting device can rapidly contract the heat shrink material over an optical fiber cable and connector portion, e.g., in about 2-20 seconds.

    • A method of manufacturing a wall thickness program onto an elastomeric tubular component, such as an expandable bladder and/or cover element, for incorporation into a packing device for use in a subterranean well includes steps of contouring upon a surface a diametrical configuration defining a wall thickness program for the tubular component. The diametrical configuration is transferred from the surface onto at least one of the walls of the tubular component as a wall thickness program whereby the transfer diametrical configuration conforms substantially as a mirror image of the program on the contoured surface. An elongated mandrel may be provided as the surface onto which the diametrical configuration of the wall thickness program is contoured, such as by machining. Thereafter, the elastomeric tubular component may be prepared on the mandrel, such as by wrapping elastomeric ribbon in layers therearound as the mandrel is manipulated. Extrusion abating heat shrinkable tape may be applied around the uncured elastomer and the elastomer on the mandrel cured under heat to transfer the diametrical configuration from the mandrel onto the tubular component. Alternatively, the diametrical configuration of the elastomeric tubular component may be machined along a constant outer diameter of a blank elastomeric tubular component.
