While I'm on a roll have another issue to throw out to you guys.
On a Wyomong horizontal well we were in the process of hanging off a 7" 29# P-110 LTC x 4-1/2" 11.6# P-110 DWCC liner system with swell packers/sleeves and the hanger started slipping. We set the liner on bottom and attempted to test the liner top packer - it did not test. We set a bridge plug above the assembly and moved the drilling rig off. We've since moved a work over in for some diagnostic work.
To make a long story short we ran casing inspection logs down to the liner top in the 7", and inside through the packer/hanger assembly down to fresh 4-1/2" casing. It seems that we have 20' of 8-3/4" open hole exposed above the liner hanger, and the PBR on top of the liner is partially collapsed. Looks as though we have a 7" part or we backed off a few joints and it fell in the rat hole.
We still have full bore access to fresh 4-1/2" casing below the liner system.
Looking for recommendations on how to repair same as inexpensive as possible yet provide a properly stimulated well. Planning a 16 stage frac at surface frac pressures below 7,500 psi. The largest ball we have to drop to open all 16 sleeves is 3.5".
