Abstract
The present invention discloses the use of nonmetallic, finely divided polymeric or natural fibers in anti-seize thread compound formulations for use on rotary shouldered, oilfield tubular good or tapered threaded connections. The addition of such fibers into formulas that do not contain metallic powders or flakes (typically utilized to provide the anti-galling properties) provides a measurable improvement in the galling and seize resistance properties. Therefore, the incorporation of such fibers provides a film strength improvement in environmentally responsible thread compound compositions, which previously would not provide the level of galling resistance to perform in severe applications such as oilfield directional or geothermal drilling.
