Abstract
A support device for tubular equipment, such as a liner inside a well, and methods for using the support device, the support device including two elements attached to each other. The two elements are: a) a cylindrical sleeve, made of ductile metal and having an external diameter slightly less than an inner diameter of the well or of a casing inserted into the well; and b) a set of tabs made of hard metal, which are spaced apart from each other and integral with the cylindrical sleeve. The tabs extend downwards from the cylindrical sleeve and an outer wall of the tabs is fitted with a series of notched formations, such as teeth, whereas an inner wall of the tabs has a conical form, the apex of which is turned down.
