Abstract:
A setting tool for setting a well tool in a wellbore includes a setting mechanism which is operative to apply a setting force to set the well tool, and an orientation indicator which indicates an orientation of the setting tool. A method of setting a well tool and engaging an assembly with the well tool includes setting the well tool in a wellbore utilizing a setting tool which includes an orientation indicator, and then engaging the assembly with the well tool, thereby fixing an orientation of the assembly relative to the well tool. A method of azimuthally orienting a whipstock in a wellbore includes setting an anchor in the wellbore, the anchor including an alignment device, and indicating an azimuthal orientation of the alignment device relative to the wellbore. The anchor setting and azimuthal orientation indicating are performed using only a single trip into the wellbore.
