The running string is secured to the existing tubular and the top of the string to be expanded is sealed around the supported running string. The pressure applied to the annular space above the seal drives the liner over the swage. A cement shoe is affixed to the lower end of the string that is expanded after becoming detached from the running string assembly. When the expanded liner bottoms on a support, generally the hole bottom, the cement is delivered through the shoe and the expansion of the top of the string into a recess of the string above continues.

| 20130056228 | Annular Seal for Expanded Pipe with One Way Flow Feature - The seal has a base ring that expands with the underlying supporting tubular. Extending from the base ring is a pleated structure with segments folded over each other so that the run in shape is small and up against the supporting tubular for run in. The pleated segments can have internal stiffeners that also add a bias radially outwardly when the structure is freed to move in that direction. A retaining band keeps the assembly retracted until tubular expansion defeats the band to allow the unitary structure to move out radially to the wellbore or surrounding tubular. The pleated portion unfolds and spans outwardly from the base ring to retain pressure differential in one direction while allowing fluid flow in the opposite direction. The assembly can be attached to a swage device so that pressure from above into the set seal can drive one or more swage members to expand a tubular. | 03-07-2013 |

| 20130284442 | Heat Treatment for Removal of Bauschinger Effect or to Accelerate Cement Curing - Materials are delivered within an expanded string before the string is subsequently compressively loaded such that the heat given off by the reaction of the delivered materials raises the fluid temperature in the recently expanded string to temperatures in a range of about 150-300 degrees Centigrade. The materials can be separated for delivery and then allowed to contact to initiate the reaction. Alternatively the materials can be delivered in separate conveyances for more immediate start of the exothermic reaction at the needed location or locations. To the extent there is curing cement about the expanded tubular, then the heat generated also reduces curing time to full setup of the sealing material. The applied heat counteracts or eliminates the Bauschinger effect. | 10-31-2013 |
