  • Patent number: 6298915
    Abstract: A stinger is fabricated with an orientating key. The stinger is lowered into a wellbore and remains atop a downhole assembly. The angular orientation of stinger with respect to the downhole assemble is also adjustable prior to entering the wellbore. The stinger acts as a guide for coupling an alignment skirt. The alignment skirt is fabricated with an alignment slot for receiving the orientation key. The alignment skirt is lowered onto the stinger and, as inclines on the skirt engage the orientation key, the alignment skirt is rotated until the alignment slot receives the orientation key. The alignment skirt and stinger are then fully coupled. The angular orientation of the orientation key can be determined by coupling an alignment skirt to the stinger, where a directional tool is affixed to the alignment skirt and performs a directional survey.
