Abstract: A suspension nut for use in a wellhead assembly of an oil and/or gas well is provided. The nut includes a lower body portion threaded for connection to the wellhead assembly. It also includes an upper body portion adapted to support equipment in the well. The upper body portion is spaced from a surface of the wellhead assembly in the absence of force applied thereto when the lower body portion is connected to the wellhead assembly. The upper body portion is adapted to be forced into abutment with the surface in reaction to the weight of equipment supported by the upper body portion.

Abstract: Methods and apparatus for effecting a fluid-tight seal between a surface of an oil and/or gas well tubing or casing and a wellhead member are provided, wherein the surface has been unprepared to form the seal. The wellhead member is positioned circumferentially about a stub of the tubing or casing. A metal-to-metal fluid-tight sealing means of the wellhead member is positioned adjacent the unprepared surface of the tubing or casing. The sealing means has at least one metallic projection positioned to extend toward the unprepared surface of the tubing or casing. The metallic projection is forced into the unprepared surface of the tubing or casing thus to form a seal therebetween.

Abstract: A communication joint for use in a well is disclosed. The communication joint includes a one-piece tubular body having an exterior surface adapted to form a slidable fluid seal with a wellhead member of the well. The tubular body includes first and second fluid conduits extending axially along and positioned in the tubular body, each conduit providing a fluid passageway independent of the other fluid conduit. Preferably, the first and second fluid conduits extend axially above and below the exterior surface of the body.
