ABSTRACT:
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 ported member for selective transmission of fluid between the exterior and the interior thereof, with each of the ported members receiving means which are movable in each of opening and closing directions for opening and closing the respective ported 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 said well by said remedial tubing, and positionable in said well in proximity to one of said ported members. The apparatus also comprises means selectively co-engagable with the opening and closing means for moving the opening and closing means in only one of opening and closing directions.
