A method and apparatus are provided for introduction into a subterranean well on a continuous length of remedial tubing which is concentrically insertable through production tubing previously positioned within the well, the production tubing carrying at least one longitudinally manipulatable member. The apparatus comprises a cylindrical tubular housing having a fluid passageway therethrough communicable with the interior of the remedial tubing for transmission of fluid from within the remedial tubing, through the apparatus, and within an auxiliary apparatus carryable within the well by the remedial tubing, and positionable in the well in proximity to one of the longitudinally manipulatable members. The apparatus also comprises means selectively co-engagable with the longitudinally manipulatable member for moving the manipulatable member to manipulated position. Hammer means are positionable on the apparatus above the selectively co-engagable means and sealingly engagable around the interior of the longitudinally manipulatable member to prevent transmission thereacross of fluid in an annular area between the exterior of the apparatus and the interior of the longitudinally manipulatable member, to the top of the well. The apparatus is activated to move the longitudinally manipulatable member to manipulated position by either hydraulic and/or mechanical tubing manipulating force.
