Background of the Invention [003] This invention relates generally to wellbore casings, and in particular to wellbore casings that are formed using expandable tubing.
[004] Conventionally, when a wellbore is created, a number of casings are installed in the borehole to prevent collapse of the borehole wall and to prevent undesired outflow of drilling fluid into the formation or inflow of fluid from the formation into the borehole. The borehole is drilled in intervals whereby a casing which is to be installed in a lower borehole interval is lowered through a previously installed casing of an upper borehole interval.
As a consequence of this procedure the casing of the lower interval is of smaller diameter than the casing of the upper interval. Thus, the casings are in a nested arrangement with casing diameters decreasing in downward direction. Cement annuli are provided between the outer surfaces of the casings and the borehole wall to seal the casings from the borehole wall. As a consequence of this nested arrangement a relatively large borehole diameter is required at the upper part of the wellbore. 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.
[005] Conventionally, at the surface end of the wellbore, a wellhead is formed that typically includes a surface casing, a number of production and/or drilling spools, valving, and a Christmas tree. Typically the wellhead further includes a concentric arrangement of casings including a production casing and one or more intermediate casings.
The casings are typically supported using load bearing slips positioned above the ground. The conventional design and construction of wellheads is expensive and complex.
[006] Conventionally, a wellbore casing cannot be formed during the drilling of a wellbore. Typically, the wellbore is drilled and then a wellbore casing is formed in the newly drilled section of the wellbore. This delays the completion of a well.
[007] The present invention is directed to overcoming one or more of the limitations of the existing procedures for forming wellbores and wellheads.

Detailed Description of the Illustrative Embodiments [0041] A self-lubricating expansion mandrel is provided. In a exemplary implementation, the self-lubricating expansion mandrel is used in conjunction with one or more methods for expanding tubular members. In this manner, the expansion of a plurality of tubular members coupled to one another using the self-lubricating expansion mandrel may be optimized.
[0042] Alternative embodiments of a self-lubricating expansion mandrel is also provided to form a self-lubricating expansion mandrel. In illustrative implementations, the self-lubricating expansion mandrel includes one or more circumferential grooves, one or more axial grooves, both circumferential and axial grooves, one or more patterns of grooves having circumferential and axial components of length and width, and/or surface textures for holding and providing a supply of grease, solid lubricant, thermo-sprayed coatings, fluoropolymer coatings, and/or self-lubricating films to surface of the self-lubricating expansion mandrel and to the interface between the tapered outer surface of the self-lubricating expansion mandrel and a tubular member during the radial expansion process. In this manner, the frictional forces created during the radial expansion process are reduced which results in a reduction in the required operating pressures for radially expanding the tubular member. The depth of the grooves, patterns, or textured surface is selected to facilitate maintaining the supply of lubrication through a period of the expansion process depending in part upon the type of lubrication whether grease, solid lubricant, thermo-sprayed coating, fluoropolymer coating or thin self-lubricating film.
[0043] In several alternative embodiments, the apparatus and methods are used to form and/or repair wellbore casings, pipelines, and/or structural supports.
[0044] Referring initially to FIGS. 1-4, embodiments of improved apparatus and method using a self-lubricating expansion mandrel for forming a wellbore casing within a subterranean formation will now be described.
[0045] FIG. 1 is a fragmentary cross-sectional view illustrating the placement of an embodiment of an apparatus for creating a casing within a new tubular member section of a well borehole, an expansion mandrel and the injection of a fluidic material into a new tubular section of the well borehole for hydraulicly moving the expansion mandrel through and thereby expanding the tubular member. As illustrated, a wellbore 100 is positioned in a subterranean formation 105. The wellbore 100 includes an existing cased section 110 having a tubular casing 115 and an annular outer layer of cement 120.
[0046] In order to extend the wellbore 100 into the subterranean formation 105, a drill string 125 is used in a well known manner to drill out material from the subterranean formation 105 to form a new section 130.
[0047] As illustrated, an apparatus 200 for forming a wellbore casing in a subterranean formation is then positioned in the new section 130 of the wellbore 100. The apparatus 200 includes an expansion mandrel 205, a tubular member 210, a shoe 215, a lower cup seal 220, an upper cup seal 225, a fluid passage 230, a fluid passage 235, a fluid passage 240, seals 245, and a support member 250.
[0048] The expansion mandrel 205 is coupled to and supported by the support member 250. The expansion mandrel 205 is preferably adapted to controllably expand in a radial direction. The expansion mandrel 205 may comprise any number of conventional commercially available expansion mandrels modified in accordance with the teachings of the present disclosure to form a self-lubricating expansion mandrel 205. In an illustrative embodiment, the expansion mandrel 205 comprises a hydraulic expansion tool as disclosed in U.S. Patent No. 5,348,095 modified in accordance with the teachings of the present disclosure.

[0052] The shoe 215 illustrated in Fig. 1, includes one or more through and side outlet ports in fluidic communication with the fluid passage 240. In this manner, the shoe 215 optimally injects hardenable fluidic sealing material into the region outside the shoe 215 and tubular member 210.

In this manner, the fluid passage 240 can be optimally sealed off by introducing a plug, dart and/or ball sealing elements into the fluid passage 230.
[0054] In the illustrative embodiment depicted, a lower cup seal 220 is coupled to and supported by a support member 250.

[0056] The fluid passage 230 permits fluidic materials to be transported to and from the interior region of the tubular member 210 below the self-lubricating expansion mandrel 205. The fluid passage 230 is coupled to and positioned within the support member 250 and the self-lubricating expansion mandrel 205.

order to optimally fill the annular region between the self-lubricating expansion mandrel and the tubular section so that the tapered or expansion conical surface of the mandrel is forced against the inside diameter of the tubular section to thereby expand the tubular member to the size of the maximum diameter of the self-lubricating expansion mandrel.
[0059] Pumping the fluid hydraulically forces the exterior tapered or conical surface of the self-lubricating expansion mandrel into direct sliding contact with the ID of the tubular member as the material of the tubular member is plastically deformed beyond the elastic limit of the tubular member thereby permanently deforming the tubular member to a larger diameter, significant pressure and heat are generated at the interface between the tubular member and the surface of the self-lubricating expansion mandrel.
The use of a self-lubricating expansion mandrel reduces the friction and facilitates the prevention of galling as a result of instantaneous surface to surface "welding" and subsequent relative movement that can occur when two metals slide under high pressure without lubrication.
[0060] The self-lubricating expansion mandrel provides grooves or troughs in a textured surface that are below the surface to surface interface contact area of the expansion mandrel.
these troughs or grooves are filled with grease or with materials that are solid under normal heat and pressure conditions and that act as lubricants under high temperature and pressure conditions. Being solid or having a very high viscosity such as with grease, allows the lubricant to be retained within the groove or trough the relative motion and extreme pressure between the mandrel and the tubular member cause small quantities of the material to move between the interface contacting surfaces to act as a lubricant. The grooves or troughs act as relative low pressure areas on the interface surface so that a substantial quantity of the lubricant continues to be retained during the expansion. Only small quantities are required to avoid metal to metal contact at the solid lubricant until interface.
[0061] The self-lubricating expansion mandrel 205 preferably has a substantially annular cross section.
The outside diameter of the self-lubricating expansion mandrel 205 is preferably tapered from a minimum diameter to a maximum diameter to provide a cone shape expansion surface.

The maximum and minimum outside diameters of the expansion cone 928 may range, for example, from about 1 to 47 inches. In a preferred embodiment, the maximum and minimum outside diameters of the self-lubricating expansion mandrel range from about 3.5 to 19 in order to optimally provide expansion of generally available oilfield tubular members.
[0062] The self-lubricating expansion mandrel 205 may be fabricated from any number of conventional commercially available materials such as, for example, ceramic, tool steel, titanium or low alloy steel. In a preferred embodiment, the self-lubricating expansion mandrel 205 is fabricated from tool steel in order to optimally provide high strength and abrasion resistance. The surface hardness of the outer surface of the self-lubricating expansion mandrel may range, for example, from about 50 Rockwell C to 70 Rockwell C.

The pressure 84 in the separate pressure line may be controlled to increase or decrease the amount of grease 71 delivered to the tapered surface 72 and to overcome pressures as might be created at the interface of the tapered surface 72 of the mandrel and the tubular member 210 when the self lubricating expansion mandre1205 is acting to expand the tubular members 210.
[0075] FIG. 12 is a fragmentary cross-sectional view of one alternative embodiment of a self lubricating expansion mandrel having a grease delivery mechanism 90, and a groove 12 and a textured surface pattern 16 for receiving, retaining and providing grease to the tapered surface 92 of a self-lubricating expansion mandrel 205 according to certain aspects of the invention. The combination of grease delivery mechanism 90, groove 12 at the leading edge 94 of the tapered surface 92 and the textured pattern 16 extending from the groove 12 toward the trailing edge 96 of the tapered surface of the self-lubricating expansion mandrel 205 facilitates movement of lubrication to the area on the tapered surface where the clearance between tubular and mandrel is minimum and expansion contact forces are found to by the greatest, thereby reducing friction and reducing seizing or galling.
[0076] The lubrication of the interface between an self-lubricating expansion mandrel and a tubular member during the radial expansion process will now be described. During the radial expansion process, a self-lubricating expansion mandrel radially expands a tubular member by moving in an axial direction relative to the tubular member The interface between the outer surface of the tapered portion of the expansion cone and the inner surface of the tubular member includes a leading edge portion and a trailing edge portion.
[0077] During the radial expansion process, the leading edge portion is lubricated by the presence of lubrication provided on the surface of the expansion cone. However, because the radial clearance between the expansion cone and the tubular member in the trailing edge portion during the radial expansion process is typically extremely small, and the operating contact pressures between the tubular member and the self-lubricating expansion mandrel are extremely high, the quantity of lubricating fluid provided to the trailing edge portion is typically greatly reduced. In typical radial expansion operations, this reduction in lubrication in the trailing edge portion increases the forces required to radially expand the tubular member.
However the retained solid lubrication continues to provide a small quantity of lubrication to keep the metal to metal interface separated and to reduce the friction.
[0078] An improved self-lubricating expansion mandrel may be useful for permitting a wellbore casing to be formed in a subterranean formation by placing a tubular member and a self-lubricating expansion mandrel in a new section of a wellbore, and then extruding the tubular member off of the self-lubricating expansion mandrel by pressurizing an interior portion of the tubular member.

In this manner, a tie-back liner is produced. The apparatus and method further permits adjacent tubular members in the wellbore to be joined using an overlapping joint that prevents fluid and/or gas passage. The apparatus and method further permits a new tubular member to be supported by an existing tubular member by expanding the new tubular member into engagement with the existing tubular member.

[0082] An improved self-lubricating expansion mandrel may be useful for permitting a wellhead to be formed including a number of expandable tubular members positioned in a concentric arrangement. The wellhead preferably includes an outer casing that supports a plurality of concentric casings using contact pressure between the inner casings and the outer casing.
[0083] An improved self-lubricating expansion mandrel may be useful for permitting for forming a mono-diameter well casing. The apparatus and method permit the creation of a well casing in a wellbore having a substantially constant internal diameter. In this manner, the operation of an oil or gas well is greatly simplified.
[0084] An improved self-lubricating expansion mandrel may be useful for isolating one or more subterranean zones from one or more other subterranean zones is also provided.

(0085] An improved self-lubricating expansion mandrel may be useful for forming a wellbore casing while the wellbore is drilled is also provided. In this manner, a wellbore casing can be formed simultaneous with the drilling out of a new section of the wellbore. Such an apparatus and method may be used in combination with one or more of the apparatus and methods disclosed in the present disclosure for forming wellbore casings using expandable tubulars. Alternatively, the method and apparatus can be used to create a pipeline or tunnel in a time efficient manner.
[0086] Although illustrative embodiments of the invention have been shown and described, a wide range of modification, changes and substitution is contemplated in the foregoing disclosure. In some instances, some features of the present invention may be employed without a corresponding use of the other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
