Bottom hole completion system for an intermittent plunger

A retrievable bottom hole anchor comprising:

• (a) a hollow cylindrical mandrel having a lower end and an upper end having a cone, said upper end adapted to accept a wireline running or pulling tool;
• (b) a J-slot sub engaging the lower end of the mandrel, said sub defining a patterned slot having a running position, a pre-set position, a set position, and a retrieving position;
• (c) a slip assembly comprising:
• i. a lower housing having an upper end comprising a slip cage and a lower end comprising a housing, concentrically disposed around the J-slot sub;
• ii. means for frictionally engaging the tubing;
• iii. at least one pin disposed between the lower housing and the J-slot sub, which pin engages the slot defined by the J-slot sub;
• iv. at least two slip arms each having an upper end and lower end, wherein the lower end is retained by the slip cage and the upper end comprises a tubing engaging slip, said slip arms moveable between a retracted position and an extended position wherein each said dog disposed to slide over the cone when the slip assembly is actuated;
• (d) wherein the mandrel and J-slot sub is moveable relative to the slip assembly between a running position where the pin is located in the running position in the slot and the slip arms are in the retracted position, a set position where the pin is located in the set position in the slot and the slips arms are in the extended position, a pre-set position intermediate the running position and the set position, and a retrieving position where the pin is located in the retrieving position in the slot and the slips arms are retracted;
• (e) and wherein the anchor may move between the running, set and extended positions by lifting and dropping the J-slot sub relative to the pin.
