In an exemplary embodiment, the lubricating substrate 200 dries and adheres to the inner surface 304 of expandable tubular member 300, resulting in the capsules 100 being held adjacent the inner surface 304.
[00030] Referring now to Figs. 4a and 4e, the method 400 proceeds to step 406 where a conventional expansion device 406a is positioned in the expandable tubular member 300. The expandable tubular member 300 may be positioned in a well bore 406b and the expansion device 300 may be positioned in the passageway 302 of the expandable tubular member 300 and in engagement with the lubricating substrate 200 and the inner surface 304 of the expandable tubular member 300. The expansion device 406a has an increasing diameter along its length such that a front end of the expansion device has a diameter substantially equal to the inner diameter A of the expandable tubular member 300 and the
rear end has a diameter B which is greater than the diameter A. In several exemplary embodiments, the expansion device may include any number of conventional expansion devices in which the device engages the inner surface of the tubular member during expansion such as, for example, rotary expansion devices or other equivalent expansion devices known in the art.
[00031] Referring now to Figs. 4a, 4e, and 4f, the method 400 proceeds to step 408 where the expansion device 406a is moved axially in a direction C through the expandable tubular member 300. As the expansion device 406a moves through the expandable tubular member 300, engagement of the expansion device 406a and the inner surface 304 causes the expandable tubular member 300 to expand from the inner diameter A to an inner diameter substantially equal to the diameter B of expansion device 406a. During expansion of the expandable tubular member 300 by the expansion device 406a, the lubricating substrate 200 reduces friction between the expansion device 406a and the expandable tubular member 300. In addition, as the expansion device 406a expands the expandable tubular member 300, the capsules 100 are ruptured between the expansion device 406a and the inner surface 304 and opened, releasing the lubricating material 104 between the expansion device 406a and the inner surface 304. As the expansion device 406a continues through the passageway 302 in expandable tubular member 300, the lubricating material 104 is allowed to flow in front of the expansion device 406a and between the expansion device 406a and the inner surface 304. As a result, the lubricating material 104 is selectively released to provide additional lubrication for the expandable tubular member 300. [00032] When selecting a lubricating material 104 for the method 400 for lubricating the interface between the expansion device 406 and the expandable tubular member 300 during the expansion process, the lubricating material 104 may be any media that may assist in reducing the friction between the expansion device 406a and the expandable tubular member 300, including any fluidic material. Several factors may be considered, including the coefficient of friction between the expansion device 406a and the expandable tubular member 300, the size and complexity of the expansion device 406a, and the length of the expandable tubular member 300. The lubricating material 104 may include wet lubricants and/or solid lubricants. It is expected that the lubricating material 104 typically needs to withstand at least 5000 psi of pressure.
[00033] In an exemplary embodiment, the lubricating material 104 for the method 400 for lubricating the interface between the expansion device 406 and the expandable tubular member 300 during the expansion process may include, for example, conventional commercial lubricants (natural and synthetic), working hydraulic fluid mud currently used in expandable tubular systems, and working hydraulic fluid mud blended with solid lubricants to
improve lubricity. In an exemplary embodiment, a lithium based (non-synthetic) multipurpose grease combined with a solid lubricant may be used as the lubricant. In an exemplary embodiment, a grease lubricant for this application may be composed of a solid lubricant in a moderately high temperature resistant thickener. In an exemplary embodiment, the lubricant may have at least 10% Graphite or 10% Molybdenum Disulfide in a thickener with a dropping point above 350-400F. In an exemplary embodiment, lubricating material 104 used in method 400 may include any or all of the following:
[00034] Exemplary embodiments of the lubricating material 104 for the method 400 for lubricating the interface between the expansion device 406 and the expandable tubular member 300 during the expansion process may consist of the following component in the weight percentages indicated:
[00035] The lubricating material 104 may optionally contain various other additives, or mixture thereof, in order to improve the basic properties. In an exemplary embodiment, these further additives may include other antioxidants, metal deactivators, viscosity improvers, extreme-pressure additives, pour-point depressants, antifoam agents, dispersants, detergents, corrosion inhibitors, emulsifiers, demulsifiers and friction modifiers.
