Claim:
A method of lowering a wireline tool on a wireline into a subsea well comprising: a) providing a rig having a riser extending from a rig floor, with the riser extending to a blowout preventer stack (BOP) on the sea floor; b) lowering a casing lubricator concentrically into the riser; c) concentrically lowering the wireline tool through the casing lubricator; d) suspending the wireline at the top of the casing lubricator; e) placing within an internal portion of a first drill pipe a stripping cable; f) connecting the stripping cable to the wireline suspended at the top of the lubricator; g) connecting the first drill pipe to said casing lubricator; h) lowering the casing lubricator and the first drill pipe; i) suspending the wireline at the top of the first drill pipe; j) disconnecting the wireline from the stripping cable; k) placing the stripping cable within an internal portion of a second drill pipe; l) connecting the stripping cable to the wireline suspended at the top of the first drill pipe; m) connecting the second drill pipe to the first drill pipe; n) lowering the second drill pipe; o) repeating steps i through n so that a drill string lubricator is lowered within the riser and until the casing lubricator is at an annular preventor located in the BOP stack with the drill string lubricator extending up to the rotary table on the drill floor; p) closing the annular preventer about the casing lubricator; q) rigging up a control head means at the top of the drill string lubricator.
