- the disclosures herein relate generally to expandable tubulars and more particularly to an expandable tubular lubrication.
- Tubular members are typically expanded by forcing expansion devices through them along their lengths, which requires a large amount of force. Efforts to reduce the amount of force necessary to expand the tubular member have involved supplying lubrication between the expansion device and the inner surface of the tubular member. Present techniques includes lubricating the inner surface of the tubular member along with supplying oil between the expansion device and the inner surface by way of a oil delivery mechanism coupled to the expansion device. These oil delivery systems increase the complexity and cost of the process.
- a lubricant comprising a lubricating substrate and a plurality of capsules in the lubricating substrate, the plurality of capsules containing a lubricating material.
- an expandable tubular member comprising a tubular member comprising an inner surface, a lubricating substrate coupled to the inner surface, and a plurality of capsules in the lubricating substrate, the plurality of capsules containing a lubricating material.
- an expandable tubular member comprising a tubular member comprising an inner surface and a means for selectively releasing a lubricating material adjacent the inner surface, the means for selectively releasing a lubricating material coupled to the inner surface.
- a method for lubricating an expandable tubular member comprising providing an expandable tubular member comprising an inner surface, coupling a lubricating substrate to the inner surface, the lubricating substrate comprising a plurality of capsules containing a lubricating material, and selectively releasing the lubricating material adjacent the inner surface.
- a lubricant comprising a dry film lubricant and a plurality of microcapsules dispersed throughout the dry film lubricant and each comprising a semi-hard shelled material containing an oil, the semihard shelled material operable to open under pressure and release the oil.
- an expandable tubular member comprising a tubular member comprising an inner surface, a dry film lubricant coupled to the inner surface, and a plurality of microcapsules dispersed through the dry film lubricant and each comprising a semi-hard shelled material containing an oil, the semi-hard shelled material operable to open under pressure and release the oil.
- an expandable tubular member comprising a tubular member comprising an inner surface, a means for reducing friction on the inner surface coupled to the inner surface, and a means for selectively releasing a lubricating material in the means for reducing friction on the inner surface.
- a method for expanding an expandable tubular member comprising providing an expandable tubular member comprising an inner surface, applying a film of lubricant that dries to the inner surface, the film of lubricant comprising a plurality of microcapsules, the plurality of microcapsules each comprising a semi-hard shelled material containing an oil, positioning the expandable tubular member in a well bore, expanding the expandable tubular member by moving an expansion device through the expandable tubular member, opening the semihard shelled material to release the oil between the expansion device and the inner surface as the expansion device moves through the expandable tubular member.

- a spherical lubricating material delivery capsule 100 is illustrated and includes a shell 102 which defines a substantially spherical cavity 102a within the shell 102.
- a lubricating material 104 is contained within the shell 102 in cavity 102a.
- the shell 102 includes a semi-hard shell material such as, for example, a wax, a polymer, a resin, or a variety of other equivalent materials known in the art.
