A novel lateral connector receptacle or LCR is provided which functions to (1) provide means for running a lower completion into a well; (2) provide means for orienting a retrievable whipstock assembly and/or scoophead diverter; and (3) provides means for attaching an upper completion to a lower completion. The LCR includes an upper section having a latch thread and smooth seal bore which respectively threadably attaches to, and mates with seals from, an orientation anchor. A middle section of the LCR includes an orientation lug for mating with the orientation anchor and providing a fixed reference point to the retrievable whipstock and/or scoophead/diverter assembly; and a lower section includes an inner mating (e.g., profiled) surface for attachment to an appropriate run-in tool. Preferably, the LCR includes three cylindrical, threadably mated subs (which respectively include the (1) latch thread and seal bore; (2) the orientation anchor lug and (3) the profiled connecting surfaces) and a fourth bottom sub. The LCR combines all of the aforementioned features providing a novel tool which allows for the ability to stack infinite laterals in a single well.
