Abstract: A method of sealing a well having a casing wall comprises transporting a camera into the casing wall making a visual recording by visually recording perforations, microfractures or other breach type damages of the wall and vertical location thereof on the wall. Selecting a vertical location for sealing the well, the vertical location being determined from the visual recording. Transporting an expandable sealing device being made of an expandable metal and a hydraulic cylinder attached to the sealing device by a shear pin into the well. Expanding the sealing device to engage the casing wall such that a gas seal is made between the sealing device and the casing wall, the sealing device being expanded through engagement by the hydraulic cylinder.

Abstract: An assembly for a thermoplastic preform for securing body part is provided. The thermoplastic preform is deformable when heated to a softening temperature by an external heating source and hardens when cooled below the softening temperature. The assembly includes the thermoplastic preform and a protective cover surrounding the thermoplastic preform. The thermoplastic preform is sealed within the protective cover. The protective cover is heat resistant up to a temperature that exceeds the softening temperature for the thermoplastic preform. The protective cover transfers heat from the external heating source to the thermoplastic preform and prevents airborne and waterborne bacteria from contacting the thermoplastic preform.
