ABSTRACT:
Method and assembly for conducting wireline operations in a deep, subsea location. The method includes providing a rig on the surface of a body of water, having a riser extending from the rig floor to the sea floor; an annular preventer positioned on the end of the riser on the sea floor; a plurality of blowout presenters positioned below the riser to prevent a blowout into the riser; and, a wireline subsea blowout preventer control head. A lubricator is lowered into the riser, with the control head attached thereto, and wherein the wireline tool is disposed within the control head. The lubricator is position within the annular preventer. Wireline operations may then be conducted. If a blowout occurs during wireline operations, any pressure would be prevented from entering the riser, and would be contained by the control head.
