Abstract

An apparatus is provided for securement onto one end of a continuous length of remedial tubing introducable into a subterranean well and concentrically insertable through production tubing previously positioned within said well, said remedial tubing having a pre-determined tensile strength. In one embodiment, the apparatus comprises inner and outer cylindrical housing members having an opening for receipt of the remedial tubing. A first element on one of the housings has a first tapered surface decreasing in internal diameter from a first end away from the opening to a second end toward the opening. Gripping means are provided and are housed within the surface and have a second tapered surface in companion contoured relationship with the first tapered surface for engagement with the remedial tubing and movable along the first tapered surface, whereby tensile load applied through the remedial tubing and the decrease of the diameter of the first and second tapered surfaces will urge the gripping means into further radially axial engagement with the remedial tubing the housing and the gripping means having a tensile strength in excess of the tensile strength of the remedial tubing. A method of utilization of the device is also disclosed, as well as an apparatus and method for completing a substantially horizontal or deviated section of a subterranean well.
