Abstract
Systems and methods are described for drilling a new secondary wellbore from a primary wellbore in which a production string is already deployed. The production string is severed below a desired kick-off location for the new secondary wellbore and the upstream portion of the production string is withdrawn from the primary wellbore, thereby exposing an end of the remaining production string. A lateral orientation device (LOD) is mounted on the exposed end of the production string. The LOD includes a shoulder for seating on the exposed end, anchoring mechanism(s) to secure the LOD to adjacent tubular(s), and seals to sealingly engage adjacent tubulars. The LOD may include a contoured surface for orientation of a tool, such as a whipstock, which may be utilized to drill a new wellbore. Alternatively, a work string may be coupled with the LOD to perform pumping operations in the wellbore below the LOD.
