Abstract
Abstract Material is supported on rotatable reel means with one end extending therefrom for connection with a well string for a well bore. Movable means support the portion of material extending between the reel means and well string. Means lower and raise the movable means whereby some of the supported material may be selectively moved into the well bore or removed therefrom along with the well string, if desired, without rotating the reel means on which it is supported during the lowering or removing procedure. Means rotate the reel support means to selectively pay out additional material for movement into the well bore or to reeve material removed from the well bore thereon. Control and actuating means effect operation of the various means as desired. Means support the well string and the material to enable the lowering of the well string and material into, and removal thereof, from the well bore.
