Abstract:
1. A mobile snubbing system for manipulating tubulars into and out of a wellhead through a wellhead axis comprising: a snubbing unit having a snubbing axis, a top end and a bottom end adapted to connect to the wellhead; a mobile transport platform for delivering the snubbing unit to the wellhead, the platform having a front end and a rear end and an open side; a frame having a first end mounted pivotally at the rear end of the platform and a second end, the frame being pivotally actuated from the platform and operable between a first shipping position, wherein the snubbing unit is supported by the frame with the snubbing axis generally horizontal, and a second operational position, wherein the frame is pivotally erected about the first end of the frame for aligning the snubbing axis of the snubbing unit with the wellhead axis of the wellhead for connection thereto; and a pipe handler having a boom pivotally mounted at a first end of the boom adjacent the rear end of the platform wherein when the frame is in its second operational position, the boom is operable between a first platform position substantially parallel to the platform for loading and off-loading tubulars at the open side, and a second snubbing position, wherein the boom is pivotally erected for loading and off-loading tubulars at the top end of the snubbing unit.
