Abstract: An apparatus and method for lubricating and injecting downhole equipment into a wellbore includes a blowout preventer, a spool for enclosing the downhole equipment, a pressure isolation window, and a hydraulic cylinder. The blowout preventer is positioned above a wellhead. The spool is positioned above the blowout preventer. The pressure isolation window is positioned above the spool. The hydraulic cylinder is positioned above the pressure isolation window. The hydraulic cylinder comprises a rod connected to the downhole equipment, and the hydraulic cylinder is used to lower the downhole equipment into the wellbore.

Abstract: A device for removing junk from a well by attaching to a tubing string a mill body with a removable milling core and lowering the assembly into a well. A movable collet and check valve are located in the milling core. The milling core can be separated from the mill body by dropping a ball bearing into the tubing and then feeding water under pressure into the tubing behind the ball bearing.
