Abstract
A method of inserting tubing into a live well bore, includes attaching a resilient piston to a lower end of the tubing, lowering the piston into a passage at a well head to locate the piston in a position above a closure which prevents the escape of fluid from the well bore through the passage, sealing the passage around the tubing above the piston and opening a path of communication between the well bore below the closure and a portion of the passage above the piston to equalize the hydraulic pressure above the piston with that below the closure. The closure is then opened and fluid is pumped from a fluid reservoir into the passage above the piston to force the piston and the tubing downwardly in the well bore. Subsequently, the piston and the tubing are allowed to descend under gravity while fluid flows upwardly in the well bore past the piston by deformation of the piston by the pressure of the fluid.
