Abstract: Embodiments of the invention relate to an assembly for forming a cased well. The assembly may include an undercut drillable cementing shoe with a casing stri ng connection at a first end. The shoe includes external tubing that forms a second end of the shoe and has a first section defining an enlarged inner diameter relative to a second section of the external tubing. The assembly may also include an earth removal member coupled to the second end of the shoe. The first section of the shoe is disposed between the earth removal member and the second section of the shoe. In another embodiment, the assembly may include a casing string having a first portion with a larger inner diameter than a second portion. T he assembly may also include an earth removal member coupled to an end of the casing string. The first portion of the casing string is disposed between the earth removal member and the second portion of the casing string.

Abstract: A method for connecting or removing a tubular 122 from the top tubular 124 of a tubular string without interrupting drilling or the circulation of fluid through the tubular string. The method comprises the steps of independently operating a rotary drive 130 and a top drive 120 to continuously provide rotational and axial movement of the string in the wellbore 105 and threadably connecting or disconnecting the tubulars by operating both drives at different relative speeds. The threaded ends of the tubulars are mated within a fluid circulating device 140 so as to circulate the fluid continuously through the string either from the circulation device 140 when the tubulars are disconnected or through the uppermost tubular 122 whilst the tubulars are connected. Also disclosed is a rotary drive mechanism (figure 3) comprising an hydraulically operated axial displacement piston (fig.3, 300) and a slip (fig.3, 132) assembly for preventing rotational and axial movement between the piston and the tubular 124 therein.

Abstract: A wellbore mill (10) has been invented that, in certain aspects, has a body (12) having a top and a bottom and, optionally, a fluid flow channel (20) extending therethrough from top to bottom with, optionally, one or more flui d jetting ports (22) in fluid communication with the fluid flow channel, milli ng apparatus (21, 23, 26) on the body including a plurality of milling inserts (26, 28), each insert mechanically secured in a corresponding recess (25) in the body, said mechanical securement sufficient for effective milling in a wellbore. A wellbore milling method for milling an opening in a selected tubular of a tubular string in a wellbore has been invented that includes installing and using such a mill.

Abstract: The present invention relates methods and apparatus for lining a wellbore. In one aspect, a drilling assembly having an earth removal member and a wellbore lining conduit is manipulated to advance into the earth. The drilling assembly includes a first fluid flow path and a second fluid flow path. Fluid is flowed through the first fluid flow path, and at least a portion of which may return through the second fluid flow path. In one embodiment, the drilling assembly is provided with a third fluid path. After drilling has been completed, wellbore lining conduit may be cemented in the wellbore.
