  • Patent number: 11898403
    Abstract: A leak-resistant pipe connection has an annular seal bulge on a pin end of the connection and a tapered seal area adjacent a secondary box shoulder of a box end of the connection. The annular seal bulge is coined on contact with the tapered seal area on initial make-up of the connection which provides a metal-to-metal seal that is very resistant to high-pressure fluid leakage even after the connection is subjected to extreme shear and tensile stresses.

  • Patent number: 9493993
    Abstract: A work string for completing long lateral well bores is assembled using small diameter drill pipe having a nigh make-up torque for a curved section and lateral bore of a well. A larger diameter drill pipe is used in the vertical section of the well to facilitate pushing the small diameter drill pipe through the long lateral bore.
