Abstract:
A method of centralising tubing (10) in a wellbore comprises either providing one or more expandable elements (14) between a tubing and a surrounding casing (12) located in a wellbore and expanding the expandable elements against the casing so as to cause the tubing to centre within the casing; or expanding one or more portions (20) of a tubing against a surrounding casing located in a wellbore so as to cause the tubing to centre within the casing.
