TorcExpander

Non explosive mechanical expansion for collapsed tubulars

Description

Configured together with the TorcDesperado Linear Actuator and the Electric Manipulation Tool (EMT) the TorcExpander is used to mechanically deform a collapsed tubular by swaging it open. The expansion segments on the TorcExpander can be engineered to fit the geometry of the collapsed tubular and are axially acitvated by the EMT and TorcDesperado and travels relatively to a cone in order to deform the tubular back towards it original shape. As this operation is controlled from surface by operating the EMT it also provides control wih respect to the mechanical position of the expansion segments. After the deformation has been made and expanded to the desired diameter the tool is retracted and reposisioned for another expansion.

 

The pads on the TorcExpander is designed to enter a collapse and force it open

Mutliple tool configurations

The TorcExpander has many different areas of use. Aside of the standard collapse expansion pads there are other options to consider.

  • Slim pads for smaller entry
  • Circular option with multiple expansion segments
  • Dimple only for centralization/standoff

 In short the business end of the TorcExpander can easily be engineered to fit the required geometry in the well bore.
