Beschreibung
Zusammenfassung:	Methods include deploying a downhole tool into a wellbore with a conveyance apparatus by mounting a tool to a distal end of a spooled conveyance apparatus, routing the conveyance apparatus around a powered sheave assembly, which includes a plurality of grooves disposed on the outer surface of the sheave to accommodate the conveyance apparatus, and providing a power source for applying torque to the powered sheave. The powered sheave assembly then deploys the conveyance apparatus into the wellbore. In some cases a traction device may be disposed between the powered sheave and the wellbore to provide axial force in both directions. The conveyance apparatus is moved through a sealing apparatus, a blowout preventer, and a wellhead, with the powered sheave, after the routing the conveyance apparatus around a powered sheave.
