摘要： A method of anchoring tubing in a bore comprising: providing tubing having a section with outer surface portions defining a tubing profile, and configured to describe an outer diameter less than a first diameter. The tubing is located within a bore having an internal diameter equal to the first diameter and defining a bore profile. The tubing is then reconfigured such that the tubing profile engages with the bore profile, anchoring the tubing within the bore.

摘要： An apparatus and a method for expanding a downhole tubular. The apparatus includes a mandrel defining at least one curved support surface. The apparatus further includes an expansion member defining a curved bearing surface for contact with the support surface and corresponding to the mandrel support surface. The expansion member is movable relative to the mandrel, whereby the surfaces are in contact and movable over one another to move the expansion member from a smaller diameter first configuration towards a larger diameter second configuration.

摘要： A method of anchoring tubing in a bore comprises: providing first tubing having a section with a wall configured to provide outer surface portions describing a diameter less than a first diameter. The tubing is located within a bore comprising a first section having an internal diameter greater than the first diameter and a second section having an internal diameter corresponding to the first diameter, with the tubing section in the first section of the bore. The tubing section is then reconfigured such that the outer surface portions describe a tubing diameter greater than the first diameter. The tubing is then axially translated relative to the bore to locate the tubing section in the second section of the bore such that the outer surface portions are restrained to the first diameter by the bore, and the outer surface portions engage with the bore.

摘要： The present invention generally provides apparatus and methods for removing liquid from a well. In one embodiment, a cable and subsurface safety valve assembly is used with a downhole pumping system to remove water from the well. The cable and subsurface safety valve assembly allows the cable to run from surface to a pumping unit while maintaining safety valve integrity. In another aspect, the cable and subsurface safety valve assembly may be adapted for use with an existing production tubing.
