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： A downhole apparatus (10; 10′) for reducing rotational and linear friction between a downhole tool (100; 100′) and/or a downhole tool string and the wall of a wellbore (B) includes an annular body portion (12; 12′) configured for location on a mandrel (102; 102′) of the downhole tool (102; 102′) and one or more rib portions (16; 16′) extending radially from the annular body portion (12; 12′), and configured to engage a wall of the wellbore (B), the annular body portion (12; 12′) and the one or more rib portions (16; 16′) are integrally formed. The annular body portion (12; 12′) is elastically reconfigurable between a first configuration in which the annular body portion (12; 12′) defines a first inner diameter and a second configuration in which the annular body portion (12; 12′) defines a second inner diameter configuration, the second inner diameter being larger than the first inner diameter. The annular body portion (12; 12′) is elastically or plastically reconfigurable between the second configuration and a third configuration in which the annular body portion (12; 12′) defines a third inner diameter, the third inner diameter being smaller than the second inner diameter.
