ABSTRACT:
An apparatus and method for directing a first and a second object into a primary and a secondary borehole respectively from a main borehole communicating therewith at a borehole junction. The apparatus includes a deflector for positioning at the borehole junction to direct the first and second objects into the primary and secondary boreholes. A retainer holds the objects relative to each other such that when the first object is aligned to be directed into the primary borehole, the second object is aligned to be directed into the secondary borehole. A retainer orienting mechanism orients the retainer relative to the borehole junction so that the objects are aligned to be directed into the boreholes. The method includes positioning the deflector at the borehole junction and inserting the objects and the retainer into the main borehole. The retainer is oriented relative to the borehole junction so that the objects are aligned to be directed into their respective boreholes. The objects are then directed into the boreholes by bringing them into contact with the deflector.
