ABSTRACT:
Conductor guides for use in drilling wells in an offshore body of water wherein the wells are positioned in close proximity one to the other. A first clamping member is removably attached to a well which includes a conductor or well head protruding therefrom. A conductor guide is spaced a predetermined distance from the clamping by means of a connecting beam that extends therebetween. The connecting beam is adjusted to properly position the conductor guide on the ocean floor at a fixed distance and directional relationship with the first conductor.
