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.
