Has anyone in the community fished and recovered severed tubing open water from a vessel using its Active Heave Compensated crane wire. (Or slickline or E-line)
The top of the fish would be in good condition and mechanically severed by E-line across the tube. The 5-1/2" tubing itself would be up to 600m long, with the water depth similar to that. The TOF should be just below the wellhead and will have a control line for the SSSV associated with it.
We're interested in the success or otherwise of the operation and what tooling was used, eg: overshot, spear, etc.
The intention is to have pulled the tubing hanger with the tree.
Thanx, Gordon and Alex for responding. We’re well aware of the weights here, and I had mentioned slick-line and E-line merely to see if anyone had experience of the methodology. Certainly agree that a spear looks to be best candidate but we’re still interested in more information from the community for the spear assembly and techniques used.
Elevators could be good insurance policy if we are able to pull the fish up from the wellhead.
This horizontal tree only has a concentric production bore. The well would have been re-entered through a Baker Hughes RLIW stack, slickline drift run to HUD, HOS set over the SSSV, and a series of varied cement barriers set with assistance of punches and tubing plugs. The tubing would be severed at 600m BSB (prefer this to be shallower) by E-line mechanical cutter and again just below the hanger which unfortunately means it is still below the wellhead datum so has to be fished.
You're correct about tubing recovery and this is a major player in RLWI vessel selection in terms of moonpool and deck space.
