comments: Pulled free of fish, hung up with grapple at 139.4m through hanger. Troubleshoot to get through. 
Attempted to pull with max 10 ton overpull - no success. 
Pulled up slowly and rotate to the right - no success. Tried to rotate to the left and pull - no success.  
Pulled and pumped with 200l/min - 4 bar, pressure increased to 30bar when took weight at 139.4m. 
RIH and engaged spear inside 10 3/4in csg, pulled same through the hanger - ok. 
Rotated it 4.5 turns to the left (2-3k torq) to reposition casing fish inside the well. Landed fish in the well and released spear. 
Attempted to pull spear through hanger - no success. Pulled up total of 3,4m from top of csg stump at 141.9m

comments: Evaluated situation. Discussed w/ onshore organisation. Meanwhile manufacturing c-plate to be able to hang off weight of the inner string
Decided way forward: 
- pull csg fish on spear 
- release spear from fish
- instal string stab above spear
- engage spear on surface, RIH fish on spear
- release spear, POOH
