Problems solved by technology

Such a large borehole diameter involves increased costs due to heavy casing handling equipment, large drill bits and increased volumes of drilling fluid and drill cuttings.
Moreover, increased drilling rig time is involved due to required cement pumping, cement hardening, required equipment changes due to large variations in hole diameters drilled in the course of the well, and the large volume of cuttings drilled and removed.

Embodiment Construction

[0017] Referring initially to FIG. 1a, an embodiment of an apparatus and method for radially expanding a tubular member will now be described. As illustrated in FIG. 1a, a wellbore 100 is positioned in a subterranean formation 105. In an exemplary embodiment, the wellbore 100 may include a casing 110. The wellbore 100 may be positioned in any orientation from vertical to horizontal. Thus, in this application the direction “up”, “upper” or “upward” refers to the direction towards the surface termination of the wellbore and the direction “down”, “lower” or “downward” refers to the direction towards the bottom or end of the wellbore.

[0018] In order to extend the wellbore 100 into the subterranean formation 105, a drill string (not shown) is used in a well known manner to drill out material from the subterranean formation 105 to form the wellbore 100. The inside diameter of the wellbore 100 is greater than or equal to the outside diameter of the casing 110.
