Abstract
An improved tubing exit whipstock and tools for installing and retrieving the whipstock are provided for directing movement of well tools from a first wellbore to a second wellbore extending therefrom. The tubing exit whipstock may include a generally cylindrical deflector body with a longitudinal passageway extending therethrough. The deflector body may also include a tapered surface for deflecting well tools from the first wellbore to the second wellbore. In one embodiment of the present invention, a mechanical connector may be provided for attaching the deflector body to an orienting and locking device to releasably install the whipstock at a selected downhole location. In another embodiment, a first fishing neck profile may be provided within the longitudinal passageway to provide means for releasably coupling the deflector body with a running tool for installing the tubing exit whipstock at a selected downhole location within the first wellbore. In yet another embodiment, the fishing neck may provide means for releasably coupling the deflector body with a pulling tool for removing the tubing exit whipstock from the selected downhole location within the first wellbore.
