ABSTRACT OF THE DISCLOSURE An orientatable adjustable bent sub having a tubular member with a first end offset to a primary axis. An adjustment sleeve, with a first end offset to a primary axis, telescopically receives the first end of the tubular member. By rotation of the adjustment sleeve the offset portion of the adjustment sleeve is adjusted in relation to the offset portion of the tubular member to produce a bend of desired magnitude. The adjustment sleeve is axially moveable between an engaged position and a disengaged position. In the disengaged position the adjustment sleeve is rotatable in relation to the tubular member permitting an adjustment to be made. An orientation sleeve telescopically receives the second end of the tubular member. By rotation of the tubular member within the orientation sleeve the bend created by the positioning of the offset portion of the adjustment sleeve in relation to the offset portion of the tubular member is orientated in a desired direction. The orientation sleeve is axially moveable between an engaged position and a disengaged position. In the disengaged position the orientation sleeve is rotatable in relation to the tubular member permitting an adjustment to be made.
