Abstract: A method for underdisplacing fracture proppant in a well bore. The method can include providing a set retainer having a passage configured to receive a wiper plug. The method may also include installing the set retainer in the well bore and injecting a proppant-laden fluid into the well bore, through the passage of the set retainer and through a perforation to create the fracture. The method may include providing a wiper plug configured to be received in the passage of the set retainer. The method may also include inserting the wiper plug into the well bore and allowing the wiper plug to wipe a portion of the proppant-laden fluid past the set retainer and into the fracture. Additionally, the method may include allowing the set retainer to receive the wiper plug.

Abstract: The functionality of a downhole tubular expansion tool is switched by: -providing the unexpanded tubular with an oversized section (7) having a larger internal width than other (non-oversized) sections of the unexpanded tubular (6);-providing the expansion tool with a control sub (1) comprising a trigger assembly (2) that is pushed outward within the oversized section and thereby switches the functionality of the tool, for example by contracting or expanding a collapsible expansion cone and/or opening a valve.

Abstract: In an assembly for lowering and expanding a tubular element in a borehole on an expansion string, at least part of the weight of the tubular element is transmitted to the expansion string via an internal upset and support means protruding from an outer surface of the expansion string below the internal upset.
