Abstract: An apparatus for handling tubular goods which includes an elongate tubular body having a peripheral sidewall and opposed ends. The peripheral sidewall has a plurality of axial slots arranged circumferentially around the tubular body parallel to an axis of the tubular body. An articulating coupling protrudes from at least one of the opposed ends. The articulated coupling includes an insert positioned within the tubular body with radial pins that engage the slots, the pins being axially movable along the slots. A gripping assembly is provided at one of the opposed ends for engaging a tubular good.

Abstract: A method of achieving a preferential flow distribution in a horizontal well bore. This method consists of the step of positioning in a horizontal wellbore a slotted liner having a plurality of slots which provide a flow area. The slot open flow area of the slotted liner varying along its length in accordance with a selected strategy of flow distribution. The preferred strategy being to create an overbalanced condition in the wellbore which promotes promote a higher flow at the toe portion than at the heel portion.

Abstract: A method of forming a metal-to-metal seal in high pressure applications with low contact stress. Firstly, providing a first elongate pressure containment member having a surface of revolution. Secondly, providing a second elongate pressure containment member having an exterior surface, an interior surface, a remote end, and a thin walled extension sleeve having a first end and a second end. The first end of the thin walled extension sleeve is conjoined with the second elongate pressure member at the remote end. The second elongate pressure containment member is of a greater thickness than the sleeve. Thirdly, coupling the first elongate pressure containment member and the second elongate pressure containment member with the sleeve positioned in close relation to the surface of revolution.
