Abstract: A wellbore tubular handling system and method for moving tubulars into a wellhead. The wellbore tubular handling system includes a service rig including a transport chassis, a mast pivotally connected to the transport chassis and moveable between a storage position and an erected position and a block supported on the mast; an upper snubbing unit pivotally connected to the mast, the upper snubbing unit including a first driving ram and a second driving ram, each including a mounted end and an outboard end, each of the first driving ram and the second driving ram being connected at the pivotal connection to the mast adjacent their mounted ends and a travelling snubbing slip assembly mounted to the outboard ends of the first driving ram and the second driving ram and being drivable toward and away from the mounted ends by the first driving ram and the second driving ram; and a stationary snubbing slip assembly configured for connection to the wellhead.
