4. The toolstring assembly (1) of any of the above claims, said toolstring (1) further comprising - a wear bushing retrieval tool (10) arranged for retrieving a wear bushing (111) in the well, and - drill pipe space-out sections (20) arranged below said retrieval tool (10).
5. The toolstring assembly (1) of any of the above claims, said casing spear tool (30) having - spear slips (32) arranged for engaging and holding the inner face of a casing, - a central bore (31) for the passage of fluids and one or more balls (45, 35, 65) - a ball seat (33) in a moveable ball seat sleeve (34) arranged for receiving a ball (35, 45) and for being sheared out and moved in order to release a slips actuating mechanism (36), said slips actuating mechanism arranged for engaging said slips (32) with an inner wall of said casing (130), said slips (32) arranged for being forced into lifting engagement with said inner wall of said casing (130) by axially pulling said casing spear tool (30) via said drill pipe string (0).
6. The toolstring (1) of claim 5, said slips (32) arranged for releasing from said inner wall of said casing (130) by downward movement of said drill pipe string (0) relative to said wall of said casing (130).
7. The toolstring assembly (1) of claim 6, said slips (32) arranged for releasing subsequent to a left-hand (LH) rotation of the drill pipe string (0) relative to the casing spear tool in combination with said downward movement of said drill pipe string (0).
8. The toolstring assembly (1) of any of the preceding claims, said casing spear tool (30) comprising - a rotatable mandrel (310) with said central bore (31), said mandrel (310) rotatable by said drill pipe string (0) and for transferring torque, in that - said rotatable mandrel (310) torque coupled in its upper end to said drill pipe string (0), - said rotatable mandrel (310) torque coupled in its lower end to the casing cutter tool (40) - an upper swivel (39U) and a lower swivel (39L) allowing said mandrel (310) to rotate relative to a barrel (311) carrying said expanded slips (32).
9. The toolstring assembly (1) of any of the preceding claims, said casing perforation punching tool (1) - comprising hydraulically operated punch knife activation mechanism (53) arranged for forcing out extendable knives (52) for cutting slits through the casing (130) wall.
10. The toolstring assembly (1) of claim 9, wherein said hydraulically operated punch knife activation mechanism (53) is activated by drill pipe string pressure set up after said ball (65) has been landed in said ball seat (64) in said wash tool (60).
11. The toolstring assembly (1) of any of the preceding claims, said casing perforation punching tool (50) - comprising a hydraulically actuated perforation gun (54) arranged to shoot, one by one in a sequential and controlled mode, and punch one hole at a time, in said casing (130).
12. A method for retrieving a casing (130) from a well (100), comprising the steps of: - assembling a casing retrieval toolstring assembly (1) of any of the preceding claims 1-14 - running said casing retrieval toolstring assembly (1) into a well on said drill pipe string (0) until said casing wall perforation punching tool (50) is near below a 9 5/8" casing (130) hanger depth, - set said punching tool (50) to a punching mode, - make said punching tool (50) punch a reference circulation hole (P0) for preparing a return circulation path from the casing annulus (131) near below said casing (130) hanger (131) depth - run-in-hole said tool string (1) with said punching tool (50) to a first, expected "estimated" free casing depth (EFCD) in said casing (130), where said casing (130) annulus (132) is freely fluid communicating upwardly to said reference circulation hole (P0); - repeat the following steps until NO fluid communication back from a test circulation hole (PI, P2, P3. ... ) until no fluid communication up to said reference circulation hole (P0) is confirmed: - make said a first, second, third, .... test circulation hole (PI, P2, P3, ..); - for each test circulation hole pull up for said perforation wash tool (60) to cover said test circulation hole (PI, P2, P3, ...) and exert a fluid pressure via said wash tool (60) through said test circuation hole (PI, P2, P3, ..) to test for fluid communication back through said reference circulation hole (P0), - assume an Actual Free Casing Depth (AFCD) to reside between said present reference circulation hole and the preceding reference circulation hole, - pulling said punch tool (50) back to the preceding reference circulation hole (PI, P2, P3, ...) wherein communication was established, - using said perforation punch tool (50), sequentially punch perforations for washing through said casing throughout said casing down to Casing Cutting Target Depth, - pull slowly out said perforated sections below Free Casing Depth and wash the debris filled annulus (134) about said 9 5/8 casing (130) until satisfactory return of flushed out annulus material, - run said toolstring assembly (1) down until said casing cutter tool (40) is at the casing cutter target depth (CCTD), - circulate in a cutter activation ball (45), set said casing spear (30) to stabilize said cutter tool (30) at CCTD, activate said cutter tool (30) and rotate until it severs said casing (130) at CCTD, - using said casing spear tool (30). excert axial pull on said drill pipe string (0) to test for free casing while at CCTD, - release said spear (30) from said CCTD depth and pull up to near a top of said severed, free casing (130'), - pull said severed casing (130') out of hole.
13. The method of claim 12, when no fluid communication up to said reference circulation hole (P0) is confirmed: - pull up from halfway from the last confirmed communication and the first confirmed no-communication perforations (PI, P2, P3, ...) and make one or more intermediate test perforations to refine the definition of the actual Free Casing Depth (AFCD).
