  • Publication number: 20130217602
    Abstract: Adding a lubricant having a metal stearate and polytetrafluoroethylene (PTFE) to a downhole fluid may lubricate a first surface once the downhole fluid has been circulated within a subterranean reservoir wellbore. Friction, torque, and/or drag may be reduced when the lubricated first surface contacts a second surface. The first surface may be or include, but is not limited to a wellbore casing, a drill string, a pipe, a formation, a drill bit, a metal surface within a mud motor, formation evaluation tool, at least one drilling tool, and combinations thereof. One or both of the first and second surfaces may be metal. The downhole fluid may be or include, but is not limited to, a drilling fluid, a completion fluid, a fracturing fluid, a drill-in fluid, a workover fluid, and combinations thereof.

  • Patent number: 8476201
    Abstract: Invert emulsion drilling fluids that have extended emulsion stability and reduced sag potential are described herein. The drilling fluids comprise an invert emulsion, a weighting agent, and a plurality of colloidal particles. The invert emulsion comprises an oleaginous fluid continuous phase, an aqueous fluid internal phase, and a surfactant. At least a portion of the plurality of colloidal particles interact with the surfactant to form an associative supporting structure that inhibits sag of the weighting agent. In some embodiments, the weighting agent comprises barite particles, particularly barite particles that are less than about 45 ?m in size. Methods for placing the invert emulsion drilling fluids in a subterranean formation via a wellbore are also disclosed.

  • Patent number: 8413745
    Abstract: Water-based drilling mud lubricants using a blend of fatty acid polyamine salts and fatty acid esters give synergistically better lubricity results than either component used separately. For example, the blends with different ratios of fatty acid diethylenetriamine salt and fatty acid methyl ester demonstrate much better lubricity in water-based drilling fluids than those where only fatty acid diethylenetriamine salt or fatty acid methyl ester are separately used. The amines in fatty acid amine salt might also include other polyamines, such as butanediamine pentamethylenediamine, spermidine, spermine, propylene diamine and propylene polyamines. The fatty acid esters might also include fatty acid ethyl ester, fatty acid glycerol ester and fatty acid trimethylolpropane ester. The carbon numbers of the fatty acids used to make the components in the lubricant blend may range from C4 to C28.
