Background of the Invention
This invention relates generally to wellbore casings, and in particular to wellbore 5 casings that are formed using expandable tubing.
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 formatior; 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 10 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 annul) are provided between the outer surfaces of the casings and the borehole wall to 15 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, 20 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. The present invention is directed to overcoming one or more of the limitations of the existing procedures for forming wellbores.

As illustrated in Fig. 4, an alternate embodiment of a method 400 for forming 5 and/or repairing a wellbore casing, pipeline, or structural support includes the steps of:; (1) providing one or more tubular members in step 405; (2) applying a coating including a first part of a lubricant to the interior walls of the tubular members in step 410; (3) coupling the first and second tubular members in step 415; and (4) radially expanding I the tubular members into contact with the preexisting structure while also circulating; 10 fluidic materials into contact with the interior walls of the tubular members having a second part of the lubricant in step 420.
- r, a prefer,ed embodiment,,n step 44C, a coating jRC!UdinY a frst pa. of a lubricant is applied to the interior walls of the tubular members, 205 and 215. In a preferred embodiment, the first part of the lubricant forms a first part of a metallic soap.
In an preferred embodiment, the first part of the lubricant coating includes zinc 5 phosphate.
In a preferred embodiment, in step 420, a second part of the lubricant is circulated within a fluidic carrier into contact with the coating of the first part of the lubricant applied to the interior walls of the tubular members, 205 and 215. In a preferred embodiment, the first and second parts react to form a lubricating layer 10 between the interior walls of the tubular members, 205 and 215, and the exterior surface of the expansion cone. In this manner, a lubricating layer is provided in exact concentration, exactly when and where it is needed. Furthermore, because the second part of the lubricant is circulated in a carrier fluid, the dynamic interface between the I interior surfaces of the tubular members, 205 and 215, and the exterior surface of the 15 expansion cone 510 is also preferably provided with hydrodynamic lubrication. In a preferred embodiment, the first and second parts of the lubricant react to form a metallic soap. In a preferred embodiment, the second part of the lubricant is sodium, calcium and/or zinc stearate.
In several experimental exemplary embodiments of the methods 100 and 400, 20 the following observations were made regarding lubricant coatings for expandable tubular members: (1) boundary lubrication with a lubricant coating having high adhesion (high film/shear strength) to the expandable tubular is the single-most i important lubricanVlubrication process in the radial expansion process; 25 (2) hydrodynamic lubrication plays a secondary role in the lubrication process; (3) expandable tubular lubricant coating offers the more reliable and more effective form of boundary lubrication; (4) a liquid lubricant viscosity and/or film strength that provides effective, 30 consistent boundary lubrication typically limits the effectiveness of additives for the mud alone to provide the necessary lubrication while maintaining drilling fluid properties (rheology, toxicity); (5) consistent reductions of 20 to 25 percent in propagation force during the radial expansion process (compared to uncoated expandable tubular 35 control results) were obtained with the following dry film coatings: (1)
polytetrafluoroethylene (PTFE), (2j molybdenum disuifide, and 3) metallic soap (stearates), these results are for laboratory tests on one inch dry pipe, in the absence of any drilling fluid; (6) a 20 to 25 percent reduction in propagation force during the radial 5 expansion process was observed; (7) synthetic oil muds do not typically provide sufficient, reliable lubrication for uncoated pipe;; (8) the coefficient of friction for expandable tubular lubricant coatings remains essentially constant across a wide temperature range; 10 (9) the expected application range for expandable tubular casing expansion is between 40 OF and 400 OF, this range is well within the essentially constant range for coefficient of friction for good coatings; and (10) good extreme pressure Doundary lubricants have a characteristic of performing better (lower coefficients of friction) as the load increases, 15 coefficients of friction between 0. 02 and 0.08 are reported for some coatings. In a preferred embodiment, the optimum lubrication for in-situ expandable tubular radial expansion operations using the methods 100 and/or 400 includes a combination of lubrication techniques and lubricants. These can be summarized as 20 follows: (1) extreme pressure lubricants/lubrication techniques; and (2) hydrodynamic lubrication from the fluid in the pipe during expansion.
Extreme pressure lubrication is preferably provided by: (1) liquid extreme pressure lubricants added to the fluid (e.g., drilling fluid, etc) in contact with the internal surface of the expandable tubular during the radial expansion process, and/or (2) solid 25 lubricants added to the fluid added to, or contained within, the fluid in contact with the internal surface of the expandable tubular member during the radial expansion process, and/or (3) solid lubricants applied to the internal surface of the expandable tubular member to be radially expanded, and/or (4) combinations of (1), (2) and (3) above. 30 Liquid extreme pressure lubricant additives preferably work by chemically adhering to or being strongly attracted to the surface of the expandable tubular to be expanded. These types of liquid extreme pressure lubricant additives preferably form a film' on the surface of the expandable tubular member. The adhesive strength of this film is preferably greater than the shearing force along the internal surface of the 35 expandable tubular member during the radial expansion process. This adhesive force
is referred TO as film strength. rue film strer,gt,, can be,r,c,eased by Increasing the viscosity of the fluid. Common viscosifiers, such as polymeric additives, are preferably added to the fluid in contact with the internal surface of the expandable tubular member during the radial expansion process to increase lubrication. In a preferred 5 embodiment, these liquid extreme pressure lubricant additives include one or more of the following: polyacrylamide polymers, AMPS-acrylamide copolymers, modified cellulose derivatives such as, for example, hydroxyethylcellulose, carboxymethyl hydroxyethyl cellulose, polyvinyl alcohol polymers, polyvinyl acetate polymers, polyvinyl alcohol/vinyl acetate copolymers, polyvinyl pyrrolidone and copolymers including 10 polyolefins, latexes such as, for example, styrene butadiene latex, urethane latexes, styrene-maleic annhydride copolymers, viscosity index improvers for motor oils such as polyacrylate esters, block copolymers including styrene, isoprene butadiene and ethylene, ethylene acrylic acid copolymers.
In a preferred embodiment, extreme pressure lubrication is provided using solid 15 lubricants that are applied to the internal surface of the expandable tubular member.
These solid lubricants can be applied using various conventional methods of applying a film to a surface. In a preferred embodiment, these solid lubricants are applied in a manner that ensures that the solid lubricants remain on the surface of the expandable tubular member during installation and radial expansion of the expandable tubular 20 member.
