ABSTRACT:
An adjustable conductor guide assembly for a sub-sea well which includes an outer ring supported on an inner guide with the axes of the ring and guide being laterally offset so that rotation of the outer ring on its support changes the position of the axis of inner guide. The improved method of aligning a conductor guide with a sub-sea well head includes the steps of supporting the conductor guide assembly on a platform installed over the well head, lowering a tool through the guide and rotating the conductor guide assembly to align the axis of the guide as close as possible with the well head, locking the conductor guide assembly in its set position and retrieving the tool. The improved tool includes a body fo passing through the guide, means for engaging the conductor guide assembly to lift and rotate such assembly, means for limiting the amount of angular movement during rotation and a string on which the body is mounted.
