Abstract: The invention is directed at a junction assembly adapted for insertion in a borehole and a system and a method for providing a junction in a borehole. The junction assembly is comprised of a primary conduit and a lateral conduit. The primary conduit has an upper end, a lower end, and defines a primary conduit bore extending through the primary conduit from the upper end to the lower end. The lateral conduit is connected with the primary conduit at a conduit junction located between the upper end of the primary conduit and the lower end of the primary conduit, wherein the lateral conduit extends within the primary conduit bore from the conduit junction towards the upper end of the primary conduit.

Abstract: A method and apparatus for slotting a pipe including a clamping system comprising a clamping surface adapted to engage at least about 50 percent of the pipe circumference and at least about 50 percent of the pipe length in a clamped position and which defines a longitudinal clamping gap oriented to permit the slotting of the pipe therethrough. A first perforating mechanism moves a cutting head comprising a plurality of cutters toward and away from the clamping gap such that the cutters perforate the pipe wall. A second independently operable longitudinal cutting mechanism moves the cutting head along the clamping gap to further cut the pipe wall by the cutters to form a plurality of discrete slots. A third indexing mechanism rotates the pipe about its longitudinal axis in an unclamped position to vary the location of contact between the cutters and the pipe wall about the pipe circumference.
