ABSTRACT:
The invention is a method for installing a wireline inside a coiled tubing. A first piston is attached to one end of the wireline. A pump-through head with a removable packing and a fluid inlet is attached to one end of the coiled tubing. The wireline and first piston are inserted through the pump-through head. The removable packing is reinstalled. Fluid pressure is applied by a pump to the fluid inlet. A section of wireline has been pumped into the coiled tubing. The pump is stopped. The packing is removed. A second piston for suspending the wireline from contact with the tubing is installed on the wireline. The steps are repeated at spaced apart intervals along the wireline until the wireline is inserted in the coiled tubing.
