Abstract:
In a borehole comprising a main borehole, a primary borehole, a secondary borehole and a borehole junction, wherein the main borehole communicates with both the primary borehole and the secondary borehole at the borehole junction, an apparatus for use in directing a first object into the primary borehole from the main borehole and directing a second object into the secondary borehole from the main borehole, the apparatus comprising:(a) a deflector for positioning in the borehole at the borehole junction in order to direct the second object into the secondary borehole from the main borehole and in order to facilitate the direction of the first object into the primary borehole;(b) a retainer for inserting into the main borehole to hold the first object and the second object relative to each other such that when the first object is aligned to be directed into the primary borehole the second object is also aligned to be directed into the secondary borehole; and(c) a retainer orienting mechanism for orienting the retainer relative to the borehole junction so that the first object is aligned to be directed into the primary borehole and the second object is aligned to be directed into the secondary borehole.
