ABSTRACT:
Apparatus and methods are provided for achieving a lateral wellbore connection in a subterranean well. In one described embodiment, a deflection device is rotatably attached to one orienting member and conveyed into a cementing shoe positioned in a parent wellbore of the well, wherein the orienting member is engaged with another, complementarily shaped, orienting member. The deflection device is then rotated to face toward the lateral wellbore-to-be-drilled and a force is applied to the deflection device, thereby fixing its rotational orientation relative to the orienting members. Cutting tools are deflected off of the deflection device to cut outward through the cementing shoe to form the lateral wellbore.
